Experimental investigation of composite steel plate deep beam infill steel frame
Abstract Steel frame and shear wall infill steel frame are two commonly lateral load resisting systems used in building structures. To realize the modulation of initial stiffness of steel structures, make it easily assembled and removed and prevent plastic hinges developing in the frame columns and collapse of all structure, a new anti-seismic infill wall system, composite steel plate deep beam (CDB), is introduced. The system uses steel plate deep beam with a precast reinforced concrete panel attached one side. This paper describes the experimental work related to the tests of CDB under cyclic loads. The experimental results of one pure steel frame (PF) and two composite steel plate deep beam infill steel frame (CDBF) with different span-height ratio are summarized and discussed, the hysteretic loops were obtained. Based on the test results, effects of the CDB on the load capacity, ductility, hysteretic property and energy-dissipation of the pure steel frame were analyzed. The results show that the CDB enhances the initial stiffness and load capacity by a large margin, and the hysteretic loops are replete and the skeleton curves have apparent stage of plastic flow, the ductility and energy dissipation capacity of the test specimens are enhanced. Lastly, regression analysis based on the tests data, and restoring force model can apply to elastoplastic response analysis of the CDBF systems. Therefore, the deep beam can be used as the first defense line of earthquake-resistance, and the steel frame can be used as the second.
