Brief overview of working stress design & its parameters

This article is extracted from an exclusive construction article written by Noel Mades, a renowned civil engineer. The article sheds light on working stress design and its criterions.
Working stress design is a useful design process in which structures or members are well-balanced toward prearranged working loads at stresses which are under their ultimate values; linear distribution of flexural stresses is accepted.
It’s a customary method applicable for reinforced concrete design (beams, slabs, columns, footing etc.) where concrete is supposed to be elastic, steel and concrete which act elastically in an organized way where the relationship among loads and stresses is linear.
Working Stress Design refers to the proportion among modulus of elasticity of steel and concrete. This conservative method of design greatly impacts modern structural design.
It is also dependent on the elastic theory under which the materials, concrete, and steel are supposed to be stressed properly beneath their elastic limit under the design loads.
Given below, the criterions of working stress design.
1. Stress-Strain Diagram
It is a diagram that demonstrates the stress and strain relationships as well as the elastic limit where the young's modulus is used and defined as the "elastic region" happens. The yield point, ultimate tensile stress, and the point of fracture are also specified.
