Civil Engineering on Instagram: "Effective length of steel members. Understanding the effective length of steel members is crucial in structural engineering! In a pinned-pinned column, the effective length (Le) equals the actual length (L) - meaning the member is free to buckle about its mid-point. This visualization shows how end conditions directly influence buckling behavior and stability. Learn how boundary conditions affect strength and design in steel structures. #steel #steelstructure #st
