...Module 10 Compression Members Version 2 CE IIT, Kharagpur Lesson 27 Slender Columns Version 2 CE IIT, Kharagpur Instructional Objectives: At the end of this lesson, the student should be able to: • • • • • • • • define a slender column, give three reasons for its increasing importance and popularity, explain the behaviour of slender columns loaded concentrically, explain the behaviour of braced and unbraced single column or a part of rigid frame, bent in single or double curvatures, roles and importance of additional moments due to P- Δ effect and moments due to minimum eccentricities in slender columns, identify a column if sway or nonsway type, understand the additional moment method for the design of slender columns, apply the equations or use the appropriate tables or charts of SP-16 for the complete design of slender columns as recommended by IS 456. 11.27.1 Introduction Slender and short are the two types of columns classified on the basis of slenderness ratios as mentioned in sec.10.21.5 of Lesson 21. Columns having both lex/D and ley/b less than twelve are designated as short and otherwise, they are slender, where lex and ley are the effective lengths with respect to major and minor axes, respectively; and D and b are the depth and width of rectangular columns, respectively. Short columns are frequently used in concrete structures, the design of such columns has been explained in Lessons 22 to 26, loaded concentrically or eccentrically about one or both...

...Failure Failure is an act or instance of a fault or manifesting the lack of success. Most people have the connotation that the concept of failure is bad or a sign of weakness however, I believe that abundance of adversity can cause a person great strength. It’s how a person address a situation, which results in lack of success. A person either learns from a setback and education themselves on how to better the outcome or do nothing, and in result face failure. I had an experience last year of failure, I had failed three of my college classes, and that impact on how I failed, the way others seen me, the way I felt, and what had learned taught me a valuable lesson.In the beginning of my junior year, I had the opportunity to take college courses. At first I was not bothered by the idea of taking on a harder task, however balancing my education and extra-curricular activities comes as a hardship to me. As I took three college courses, participating in band as a Dancer, and also being a junior in high school, my time management skills were at default. In result, I failed my three...

...effective organizational leaders share. Without these characteristics, initiatives and change can fail. Leaders can take many different steps to help keep projects from failing. Leaders need to be self-aware of how their actions are perceived by those they manage (Moment, 2007). Employees will sometimes mirror the behavior of managers. Aghdaei (2008) talks about the philosophy of “shadow of a leader,” where the leader demonstrates the wanted behavior (p. 16). Leaders should model hard work for employees (Weiss, 2000). Aghdaei (2008) states that “when you repeatedly demonstrate meaningful, positive behavior, people are motivated to follow” (p. 16). Leaders must have enthusiasm for their work so that it spreads to those whom they supervise. That involves leaders believing in the company in which they work. “The ability to inspire loyalty and build relationships is a key component of leadership” (Newcomb, 2005, p. 35). “The CEO who wants to be a true leader must be the most vivid example of the culture at work. Only then can the CEO inspire passion in the rest of the team” (Hesselbein, Goldsmith, & Somerville, 2002, p. 124). To get the best out of workers, leaders need to be able to motivate them (Moment, 2007). Leaders should look to all of their employees for new ideas and solutions (Hesselbein, Goldsmith, & Somerville, 2002). Leaders should also “cultivate, champion, and then support” new ideas and “provide an environment for the development and expression of...

...“When we give ourselves permission to fail, we, at the same time, give ourselves permission to excel.” This a quote from Eloise Ristad that has stuck with me throughout my life. It is a quote that has gotten me pass the failures that I have had. Of course failure can be fundamental to later success but that is not what is felt in the moment. Sometimes these moments can be devastating and hard to get past but with realizing that comes a great opportunity to progress and learn. It was my junior year of high school and I was trying out for next year’s cheerleading season. I had been cheering since I was in junior high school and even before then for club teams. This was my fifth consecutive year of trying out for Troy’s team and I was especially...

...people who do not have the courage to take risks do not accomplish anything in life. I would add to that and say that people who do not have the courage to take more than one risk will never become a true success or a champion in life. Muhammad Ali had the courage to rise up despite criticism. He also had the courage to train hard, keep going despite his failures in his life, speak up for what he believed in, and stand up for what he believed in. The fact is that courage was a centerpiece in his life. But, you will find that courage plays a big part in every champion's life. Everyone who comes out a winner had to have the courage to start going after something they wanted in the beginning. It's uncomfortable for everyone to start, and there is always a fear that you won't be good enough, but eventual winners gather up the courage to take the first step despite their fears. And when failure comes around - and it always does - champions needed to gather up more courage to keep going after their dreams. They have to believe in themselves despite the failure. They had to keep trying even though their efforts resulted in failure...

...successes and failures? How much of Apple's success can be linked directly back to its culture? How do the actions of Apple apply to the TCOs? The best way I can most effetely answer these questions is to start with the second question, How much of Apple's success can be linked directly back to its culture? I think that a Apples success can be significantly linked directly back to its culture. This question is easily supported by what happened when Apple hired John Sculley as their President and CEO in 1983 and pressured Steve Jobs to resign in 1985. During this period of time Sculley brought a corporate culture from Pepsi into Apple which was a significant change from what the company had been used to with Jobs leading the company. During the time that Sculley was at the realm Apple saw significant failures in which I will outline when answering the next question and he changed business models which adversely affected Apple to the extent that some say he almost drove Apple into the ground for good. After Jobs return in 1997 he immediately started driving the businesses culture in a completely different direction in which he focused on the experience his products gave the user and went on to inspire others in the company to be creative and come up with innovations that changed the world forever. I’ve taken events from an article I found called, “30 pivotal moments in Apple’s history” (Linzmayer, 2006) and segmented what they feel to be the 30 most pivotal moments in Apples...

...I saw myself grimacing while in a half split because I couldn’t push myself level with the ground. I saw my fingers crooked and my arms bent at odd angles. I saw my forehead scrunched with concentration as I tried to perform a full pirouette. The images blurred as my misery overwhelmed me and tears stung my eyes. Yet, that day I forgot to also consider that dancing filled me with joy. Yes, I was only half decent at ballet, but I was eleven years old and had time to improve. My dancing career so far was not a clear and accurate representation of the future. Unfortunately though, I deemed myself a failure at dancing and abandoned...

Mom said I’ve earned another shot up at University Park. Dad is still being stubborn, but he’ll come around eventually. I haven’t been this happy since high school.” “Seems like it. You better make the most of it.” “I will. I have to.” “If you don’t mind me asking…where were you the past year?” “Lost.” “What do you mean?” “I wish I knew.” “You know—I went to Penn State too—was there for 8 years and 3 degrees. I knew many of the most talented and brilliant people there. Professors, students, and—“ “You were one of them.” “—and you are too. You’re just as talented as any of them, including me.” “I know Mark, I agree with you.” “Then…can I ask you something?” “Is that rhetorical?” “How badly do you want to succeed?” “As badly as you did…as badly as you still do.” “Then why were you struggling so much? “Because I just wasn’t…me.” “For how long?” “—the past two years.” “So…help me understand what you’re talking about?” “You already know everything that’s happened with me...it’s all been in our conversations; little bits here—small pieces there.

...faced with their judgment day and presented with an account of their lives. Everyman is a man wealthy materialistically, while Faustus is wealthy in arts such as logic, medicine, law, and divinity. Everyman represents the men in society who are fixed in their material lives and lose sight of Christ. He befriends men who abandon him while on a pilgrimage to Christ, learning that what he once valued, his wealth, is useless to him when he has to account for his lack of good deeds. Faustus unlimited intelligence, yet he is dissatisfied with his gift; he would prefer experiment with black magic. Faustus gives his soul to the devil in exchange for the power to perform black magic, but he is ultimately damned to hell because of his decision and failure to recognize his fault. Faustus and Everyman fail to recognize Christ and their afterlife is left at stake. On the road to salvation, death serves as a groundbreaking event in the life of mortal men. Throughout their quest, Everyman and Faustus struggle to prove themselves worthy of greater afterlife through misusage of their mortal lives. Everyman is approached by the devil with a pilgrimage which he must partake, one where he will not come back alive. He seeks help in that those who befriend and abandon him during his lifetime such as: beauty, goods, and knowledge cannot help him on his journey. Good Deeds is the only character that could assist everyman, but Good Deeds is outweighed by sin, and is ultimately unable to help Everyman....

...Is it good to foster a culture that reinforces failure? (Chapter 8) The fact that failure is something that most businesses have a difficult time accepting, does not mean it is not a blessing in disguise. In this reading selection, the reader can understand more thoroughly the importance of accepting failure in a product’s life cycle and its silver lining for companies. It takes a very skilled leader-manager to recognize the benefits of failure. Whether a failure costs a company almost everything it has, or it is done inexpensively, it is one of the most vital components of a company’s growth. To be innovative in a world where products become obsolete in almost the same moment they are invented, failure needs to be looked at through the perspective of, “How can we benefit from this not working?” Many companies take even more risk by presenting the fact that failure with new products is likely when presenting to potential investors. It is extremely important to do so because many will not take that concept into consideration when analyzing a new product, it may even be overlooked altogether. Some may take the viewpoint that speaking of failure before a new project is initiated would be detrimental to the product, and furthermore, the company’s success. However, failure needs to be recognized as part of the risk-taking, innovation process. It allows a company to understand its customers and their needs on a much greater scale. It also provides what needs to be reinvented...

...Reliability Evaluation of Bangladesh Power System Using Cumulant Method Nahid-Al-Masood Department of Electrical and Electronic Engineering Bangladesh University of Engineering and Technology Dhaka, Bangladesh E-mail: nahid@eee.buet.ac.bd S. Ahmad1, G.A.K.Biswas, A.U.Elahi, N.M.Zakaria Department of Electrical and Electronic Engineering BRAC University Dhaka, Bangladesh E-mail: 1 shahriar.me@gmail.com Abstract—In recent years, power systems are frequently operating under highly stressed and unpredictable conditions because of not only the market-oriented reform of power systems but also the integration of various renewable energy sources. The uncertain factors resulting from the market constraints and the inherent randomness of renewable energy set higher requirements on the reliability of electric networks. This paper presents the reliability assessment of Bangladesh Power System (BPS). Reliability index, loss of load probability (LOLP) of BPS is evaluated using cumulant method. The rationale for using the cumulant method is to take advantage of its computational efficiency. BPS has sixty one generators and a total installed capacity of 5275 MW. The maximum demand of BPS is about 5000 MW. The relevant data of the generators and hourly load profiles are collected from the National Load Dispatch Center (NLDC) of Bangladesh and reliability index ‘LOLP’ is assessed. The simulation results show that the LOLP of BPS is 2.06%. Keywords—cumulant method, convolution...

...What is leadership moment? Moments that defines us. In life and in leadership, we experience moments and events that define who we are - as leaders and human beings. What we do, what we say, and the distinctions we make during these defining moments impact and define who we are and what we value and stand for - in our mind and in the mind of others. Defining moments occur periodically through life and through a leader’s career, often times unrecognizable as being “defining” until sometime later on. What makes certain moments in our leadership career defining? What impact do these moments have on defining who we are as leaders? How do those around us react to how we behave during a defining leadership moment? As a leader, why should I be concerned with a moment or experience in the past? What difference do these defining leadership moments in our past make anyway? Defining leadership moments are also moments or experiences where your words, behaviors or decisions - how you handle yourself in a given situation - creates an impression that helps to define your leadership in the minds of others. How you are distinguished by others as a result of these defining leadership moments contributes to your leadership legacy in action. It is the impact your actions have on others that create the distinctions that contribute to your leadership legacy.

...simply states that you must not “try” to do something, either you do it or you don’t. In order to accomplish your goal. you must commit to it with your whole heart and banish all possibilities of failure that can render you unsuccessful. Committing to something completely and totally is the only way in which you can say that you have truly "tried." His philosophy connects with the world because many people use this saying to help boost them past their “wall of failure”. It encourages them to do rather than try and give a un-whole-hearted effort. Another philosophy of Yoda is, “ Clear your mind of questions, be still.” This philosophy states that one must remove any doubts of the future. Today’s mindset extends to people believing that the future holds the power. However to influence the future, one must live in the present to dictate what will happen in the future. By following this saying, we can gain a greater understanding of the universe. By removing the doubts we have of the future we are able to not be afraid of what the future holds in store for us, the unknown. While the unknown or uncertainty is a scary thing to face, one must pass this obstacle to wholeheartedly attain their goals. Living in the moment allows us to be more connected with the world, because in reality the moment is all we really have. The future merely exists in the future as we wait for it to pass by.

...“Success is somebody else’s failure. Success is the American Dream we can keep dreaming because most people in most places, including the thirty million of ourselves, live wide awake in the terrible reality of poverty.” LeGuin essentially claims that in order for one to succeed, another must fail; however, success stems from one’s own failure. LeGuin mentions the American Dream, which, for years, has been perceived by most as the hope of success and prosperity. Closely akin to this is the American Spirit. Since the early settlement of Jamestown, Virginia, we Americans have done nothing less than to keep our heads held high and do whatever it takes to achieve success. As concluded by Claudia O’Keefe in The Traveling Bra Salesman’s Lesson, “Only when we admit that the future awaits us can we embrace a more inclusive and thrilling successor…” O’Keefe reminds us how important it is to live for the future – not necessarily the moment. It is exactly this that the American Spirit adheres to, as remarked by President Barack Obama in his Independence Day address on July 4, 2009: “…It is what has always led us, as a people, not to wilt or cower at a difficult moment, but to face down any trial and rise to any challenge…” This has been exactly how we, as Americans, have conducted ourselves since the settling of Jamestown, Virginia in 1607. We make our mistakes, do our due diligence, and make success a reality. In this way, success stems from, and is one’s own failure – not another’s. In the...
