The structural design of reinforced concrete has evolved from the Working Stress Method (WSM) to the more robust Limit State Method (LSM). Dr. B.C. Punmia’s text details this transition, explaining how LSM ensures both safety and serviceability under ultimate and day-to-day working loads.

The text explains traditional WSM, where structural members are analyzed using elastic theory under service loads. It highlights its limitations, such as neglecting the plastic behavior of concrete and over-designing sections.

The limit state design approach is a method of designing reinforced concrete structures that takes into account the various limit states that a structure may experience during its lifetime. These limit states include the serviceability limit state, which ensures that the structure remains functional and comfortable for users, and the ultimate limit state, which ensures that the structure can withstand extreme loads without collapsing.
