Difference between WSM(Working Stress Method) and LSM(Limit StateMethod)

S.NO. Working Stress Method(WSM) Limit State Method(LSM) 1. Follow Hooks law i.e. stress-strain diagram is linear. Does not follow Hooks law, hence stress-strain diagram is non linear. 2. All tensile stresses are taken by steel only and not by concrete. The tensile strength of concrete is ignored. 3. Factor of...

Why we use reinforcement in Beam?

Why We Use Reinforcement Bars in Beams? Reinforcement bars, also known as rebar, are used in beams to provide additional strength and durability to the structure. The use of reinforcement bars in beams is essential to ensure the safety and stability of the structure, especially in buildings and bridges. Here...
