Advantages of LSM Over WSM According to Duggal
- Realistic Behavior: LSM respects that steel is not perfectly elastic; it yields and strains hardens.
- Uniform Reliability: The use of partial factors distributes safety rationally—higher factors for unpredictable loads (wind, earthquake) and lower factors for well-known dead loads.
- Economy: By allowing controlled plastic deformation and higher working stresses, LSM typically yields more slender, lighter structures than WSM, reducing steel consumption by 15-25%.
- Explicit Serviceability Checks: WSM implicitly assumed that if stress was under yield, deflections were fine. LSM forces the engineer to check deflection, vibration, and cracking separately.

One cannot neglect roof trusses, gantry girders (subjected to moving wheel loads, impact, and longitudinal drag), and bracing systems. The book includes typical truss configurations and load combinations using wind load analysis. Limit State Design of Steel Structures S
