Modelling of riveted joints in Finite Element Analysis (FEA) programs can be a complicated task. Previously beam elements have been used to represent fasteners where the shear stiffness of the beam has been approximated to that of the shear stiffness of the rivet. Errors result in this method since the beam can also support bending. Test results of rivets joining sheet metal components have shown that beams are not ideal at simulating a rivet in FEA. An acceptable method for simulating riveted joints in FEA

start with, a CRT monitor in general is nothing more than cathode ray tube with millions of diminutive red, green and blue phosphor dots. The working principle of CRT monitor is sustained by the theory of electron beam traveling across the tube to the area of deflection system where the beam is given direction to a specific pixel on the screen. The first CRT monitor has been invented in 1970s. However, monitor was greenish and the only possible sphere of usability was text-based computers. On the other

IN FLOORS 1 Integrated Building Services installation in Floors 1.0 Floor Systems Floor structures comprise beams and slabs. The beams are attached to Columns that are placed in the optimum locations for effective use of the space. Column-free space has become an important design requirement in modern commercial buildings to achieve flexibility in use. Many long-span beam systems have been developed with spans of up to 18 m, which means that internal columns are not required for many building

Standard oscilloscopes use an electron beam, which is swept across a phosphor screen, the vertical deflection of the beam being proportional

rigid depending on their stiffness relative to the framing in which they are used. Engineers consider some joints as pinned in their structural analysis, even though it is common knowledge that all joints exhibit some rotational constraint. For example beam-tocolumn joints made with a thin and non-extended end plate are actually semi-rigid but are modelled as frictionless pinned connections. Until recently there has been no reliable evidence that the idealisation of such joints is a safe building design

Portal Frames Portal frames are generally low-rise structures, comprising columns and horizontal or pitched rafters, connected by moment-resisting connections. Resistance to lateral and vertical actions is provided by the rigidity of the connections and the bending stiffness of the members, which is increased by a suitable haunch or deepening of the rafter sections. This form of continuous frame structure is stable in its plane and provides a clear span that is unobstructed by bracing. They are
