Experimental Study on Seismic Behavior of Full-Scale New Steel Truss Coupling Beams

Abstract:

Steel truss coupling beam is a new type of steel coupling beam structure. To investigate seismic behavior of this coupling beam, low cyclic loading tests for four full-scale specimens of steel truss coupling beam are presented. The specimens are designed considering three factors which are T-stub steel, angle steel and material strength. The experimental data show that steel truss coupling beam has good ductility, and can consume a great quantity of earthquake energy. By enlarging the sections of cross abdominal trusses and chord members, bearing capacity and stiffness of the whole coupling beam are greatly increased.
