Design of Eccentrically Loaded Single-Angle Compression Members

Dr. N. Subramanian explores the complexities of designing eccentrically loaded single-angle compression members used in structures like roof trusses, bracings, and transmission towers; addresses challenges such as unsymmetric cross-sections, eccentric loading, and the resulting failure modes, including local, flexural, and torsional-flexural buckling; and also reviews the impact of recent revisions to the IS 800 code, providing engineers with valuable insights into updated strength calculations and design procedures.
