Node Of The Flat Steel - Concrete Composite Coupling Beams With Concrete Shear Wall Restoring Force Model Of Experimental Research And Analysis

In recent years, the steel - concrete hybrid construction application in our country indicated that it concurrently has the steel structure and the concrete structure merit, and the remarkable technology economic efficiency and the social efficiency. Shock evil and the experimental study indicated that construction structure collapsing mainly is because structural member dissipated energies ability and plastic deformation ability are smaller than the ability with which need, the steel-concrete composite coupling beam and the concrete shear wall joint is one kind of new composite joints, knowing failure patterns of the steel-concrete composite coupling beam and the concrete shear wall joint in the plane, and seismic resistance performance such as the hysteresis responses, the ductility, the dissipated earthquake energies ability, resiliency model and so on ductility at the end of coupling beam under low frequency cyclic load action, which will be the vitally significant to instructing design and promoting The hybrid hull core structure with steel-concrete composite coupling beam or shear wall structure, and the correlation regulations formulation. At this point, the paper mainly does work as follows:1) Based on the summary research results in the past, applying theory such as mechanics, RC structure non-linear and so on to preliminarily theoretically analyzes steel-concrete composite coupling beam joint, and propose the joint experimental plan, and carries on 2 full scale steel-concrete composite coupling beam and concrete shear wall joint test in the plan under low frequency cyclic load action.2) According to the experimental phenomenon and the theoretical analysis, research the joint of the hysteresis responses, the ductility, the dissipated energies ability at the end of coupling beam under low frequency cyclic load action3) In order to carry on the earthquake resistance analysis, it needs to be modeling the hysteresis curve which obtain from the laboratory data, enables it more ideally to respond the component the displacement-load relations under the earthquake load action, and considers the strength and the stiffness degenerated rule, according to the tentative data and the regression analysis, proposes the joint skeleton curve model and the resiliency model.
