Part of: Connection Flexibility and Steel Frames


A nonlinear analysis of plane elastic frames is presented. The static loading consists of both eccentric concentrated loads (near the joints) and uniformly distributed loads on all or few members. The joints can be either rigid or flexible. The mathematical formulation is presented and the solution methodology is outlined and demonstrated through examples of two-bar frames and portal frames. The emphasis is placed on obtaining buckling loads and prebuckling and postbuckling behaviors, whenever applicable. Furthermore, the effects of the joint stiffness on the response characteristics are fully assessed for both types of frames.
