The Indian Standard code can be dense and difficult to navigate. Duggal breaks down clauses related to tension members, compression members, and beams into step-by-step design procedures that make sense for a practicing engineer. 2. Focus on Connection Design
Steel strength can vary based on manufacturing quality. Duggal explains the three critical partial safety factors for material resistance defined by IS 800:2007: Resistance governed by yielding: Resistance governed by ultimate stress (fracture): Resistance of connections (shop/field welding or bolting): γmwgamma sub m w end-sub 3. Plastic Analysis and Section Classification limit state design of steel structures by sk duggal
Duggal does not shy away from the complexities of LSM. The method requires iterative calculations, a thorough understanding of buckling curves, and careful second-order analysis (P-$\Delta$ effects) for multi-story frames. For beginners, the multitude of partial factors and code clauses can be daunting. Furthermore, LSM demands high-quality fabrication; its reliance on plastic behavior is invalidated if brittle fractures occur due to poor welding or low-temperature exposure.
