Types of Design Method| Difference Between Limit State Method vs Working Stress Method

These Lectures series is only designed for Undergrade Students of Civil Engineering, who are interested to develop the concept of design of Reinforced concrete Structure i.e. Basic Design Philosophy, Limit state design method, Working Stress Method, Analysis and design of Concrete section, Design of beam for Flexural, Design of Beam for shear Only and Shear Plus Torsion Design, Design of one Way Slab, Design of Two way Slab, Design of Uniaxial column, Design of Bi-axial Column Design of Column footing, Design of Square Footing, Design of Combine Footing. Design of Wall Footing, Design of Shear wall, Design of Retaining Wall, Design of stair design and Design of All Structure in ETAB. Lecture # 4 of Reinforced concrete design Covers the following. In, this Lecture, I have demonstrated the basic Design approach used in designing of Reinforced Structure. 1) Limit State Method 2) Working Stress Method Limit State method is the design approach in which, the loads are amplified based on code recommendation and capacity of a structure elements is reduced based on either the member is tension-controlled section, compression-controlled section, or transition-controlled section. While in working stress methods demand is kept constant and capacity is divided by 2.
