Design of beam using Working Stress Method (WSM)
W orking stress method is one of the oldest design philosophies, and now it is applicable at very fewer places. Nowadays, other methods are used instead of working stress method as they rule out the limitations of WSM. The alternative methods that are used are Limit State Method and Ultimate Load Methods which uses loads factors and ultimate strength in the design. In it, we start with the analysis part, which is practised in the Mechanics of Solids. The first task is to find bending moments, shear forces, reaction forces at the supports, axial forces, etc. Let us look at the bending stresses first as they produce both types of stresses (compressive and tensile). The theory of bending ( plane section remains plane before and after bending) is applicable. Still, one thing to note is that this theory is applicable only when the perfect bond between two different materials exists and no-slip occur between the material. Stress-strain Distribution: Since it i...
