Engineering reports Adapted from: Braham M, Jaspart JP. Is it safe to design a building structure with simple joints, when they are known to exhibit a semi-rigid behaviour? Journal of Constructional Steel Research, 60, 2004, 713-723. Annotated model Executive Summary This report evaluates the assumption that joints which display semiPurpose rigid behaviour can be modelled as frictionless pinned joints in building design calculations. The idealisation is evaluated by Method comparing computer simulations

Good Posture * Keeps bones and joints in the correct alignment so that muscles are being used properly. * Helps decrease the abnormal wearing of joint surfaces that could result in arthritis. * Decreases the stress on the ligaments holding the joints of the spine together. * Prevents the spine from becoming fixed in abnormal positions. * Prevents fatigue because muscles are being used more efficiently, allowing the body to use less energy. * Prevents strain or overuse problems

mobility of the joints on which they are performed. These exercises reduce stiffness and will prevent or at least slow down the freezing of your joints as the disease progresses and you move less often. Range of motion is the term that is used to describe the amount of movement you have at each joint. Every joint in the body has a "normal" range of motion. Joints maintain their normal range of motion by being moved. It is therefore very important to move all your joints every day. Stiff joints can cause

Osteoarthritis? Osteoarthritis (or OA for short) is the most common type of arthritis and is associated with joint pain and reduced range of motion and quality of life. It is a vast, chronic condition which affects the weight bearing joints and involves biomechanical, morphologic and biochemical alterations of the matrix and cells of the bone. Common symptoms are pain in the affected joint area and loss of mobility however, structural changes may occur without any accompanying symptoms. In itself

The knee is the largest joint in the human body, it is also one of the most stressed and complex. This makes it easy for injuries to happen. An estimated 6,664,324 knee injuries were presented to ER’s from 1999 through 2008, equaling 2.29 knee injuries per 1,000 individuals. The biggest age group with knee injuries during that time was 15-25 year olds. Knee injuries are so common because of how complex the knee is. The knee is formed by three bones, the patella the tibia and the femur. In

are the second most common injuries that occur at the knee joint according to the Journal of Orthopaedic & Sports Physical Therapy.1 Most often these structures are injured during planting and rotation movements, with the medial meniscus vulnerable with an external rotation motion and the lateral meniscus vulnerable to injury during internal rotation motions.2 Following an injury to the menisci there is often pain felt deep in the joint line with increased effusion occurring at the knee shortly after
