Design Philosophies for design of RC structures
T o have a properly designed structure which fulfils all the requirements like proper durability, functioning, etc. We follow certain design philosophies. Every philosophy has some set of assumptions, and based on the premises, some ideas are suggested. So, let us start one by one. Working Stress Method (WSM) : Now it is an outdated method, and it is used occasionally. Today, it is used in a place where the complete analysis of the structure is complex, and no risk is allowed like an overhead water tank, chimney, etc. This traditional method has the following assumptions: The material behaves elastically, means stress-strain linear relation will be applicable. The adequate factor of Safety is applied so that the working load is well below the material strength. Here, we raised a term factor of Safety ( FOS) which is given by FOS = Strength of material / Allowable strength of the material Since in this metho...
