Abstract
Due to the inelastic property of beam-to-column connections, the stability of semirigid frames is affected not only by the loading and the unloading characteristics of connections at the critical points, but also by their load history up to these points, thus resulting in a complicated buckling behavior. Herein, utilizing the accurate method of analysis developed by authors, we precisely examined how the stability of semi-rigid frames is influenced by the modeling of connections, the load conditions and the load history caused by the cyclic wind load. With the information, so obtained, we further discussed the way of stability check to be used in design.
