Experimental Study of Steel Frame-bent Structures with Braces

11952,11953,11954

To study the seismic behavior of steel frame-bent structures, substructure model was designed and carried out quasi-static cyclic loading tests by taking certain typical engineering for example. The experimental analysis results show that the steel frame-bent structures has good seismic behavior, being of plump load-displacement curve as well as good energy dissipation and ductility capacity. Meanwhile, the compressive buckling of braces was an important reason for problems of overall out-of-plane distortion and distortion at node junction.
