ANALYSIS OF LATERAL BUCKLING IN PLANE FRAMES

A general and systematic method of analyzing the elastic flexuraltorsional bucking of rigid-jointed plane frames with I-section members and subjected to in-plane loads is linearize the flexural-torsional differential equations. The buckling equations, which consist of the bending and torsion differential equations, and the boundary, compatibility, warping, and joint equilibrium equations are solved numerically by the method of finite integrals, and the critical load factor is obtained iteratively. A compurter program is developed in which most of the equations are progressively eliminated. This leads to significant reductions in the storage requirements and the computing time.
