If you are wondering how Duggal stacks up against other authors, here is a quick comparison:
Understanding the shift from the Working Stress Method to the Limit State Method is vital for modern engineering. Working Stress Method (WSM) Limit State Design (LSD) Elastic theory of materials Plastic behavior and ultimate strength Safety Factor Single Factor of Safety applied to material stress Multiple Partial Safety Factors for loads and materials Economy Results in heavier, less economical sections Results in lighter, highly optimized sections Realism Does not account for actual load variations Models realistic load combinations and material variations Key Highlights of S.K.
