Abstract

One of the problems of current interest to structural engineers is the behavior of compression members that are parts of rigidly connected structural frames and are consequently subjected to varying end restraints. A method is presented herein for the calculation of these end restraints and the effective lengths of compression members under different load conditions. It is demonstrated that the end restraints decrease and that the effective lengths increase as loads are increased, until the frame buckles. It is shown that when a truss buckles all members tend to fail simultaneously.
