Abstract:Pseudostatic force tests of 1∶2 scale models including two steel frames with semirigid connections and a steel frame with dogbone rigid connections are carried out in order to obtain the elasticplastic behavior of semirigid connections of steel frames under cyclic loading as well as to analyze the collapse characteristic after structural ultimate strength has lost and the coming order of plastic hinges. The M-θr curve, skeleton curve and seismic behaviors are analyzed, and all kinds of characteristic of hysteretic behavior are gained. Experimental basis is raised for design and construction of steel frames.
