Working Stress Method Limit State Method
 WSM is an elastic design method.
 The stress in material is allowed to go beyond the
yield limit and enter into the plastic zone to reach
ultimate strength.
 LSM is strain based method.
 WSM is deterministic approach.
 In this design method, members are designed to
never go beyond their elastic range.
 LSM is a plastic design method.
 WSM is stress based method.
 LSM is non-deterministic method.
 Factor safety is used find the allowable stress.  Partial Safety factors are used for Design
WSM Vs LSM
