It is well known that a structure without any fixed point can not be analyzed. It would be as if floating in a state of weightlessness. Any load that we apply to the structure will move the structure. If the load is constant, it will speed up as per the known equation F = m…
Introduction It is common to find complex structures in both engineering and architecture. We understand complex structures that are formed by various type of structural elements: walls, bars (pillars and beams), slabs, membranes, cables, etc. To tackle with these structures, regardless of which is done by hand or with the help of computer programs, the…
In the field of analysis of building structures, we tend to use the linear calculation. What does that mean? It means the results (reactions, stresses, displacement and deformation) are proportional to data (actions). So, if we get a 3 mm sag on a steel beam when we apply a load of 50 kN, no need…
