Welcome to the course on working stress method. We are going to discuss design philosophies involved for structural design of RCC Structures. The architect plans the layout so as to satisfy the functional requirements and also ensures that the structure is aesthetically pleasing and economically feasible. In this process, the architect often decides the material and type of construction as well. The plan is then given to a structural engineer who is expected to do locate the structural elements. He then makes the strength calculations to ensure safety and serviceability of the structure. This process is known as structural design.
So Structural design is the methodical investigation of the stability, strength and rigidity of structures. The basic objective in structural analysis and design is to produce a structure capable of resisting all applied loads without failure during its intended life.
