【Abstract】 Through the experiment with two concrete filled steel tubular frame structures under reversed cyclic loads, which have the same shapes, materials and dimensions, several characteristics of these frame behaviors, such as failure features, deformation and energy consuming ability are studied. Seismic behaviors of the concrete filled steel tubular frame structures are also analysed.Experimental basis is provided for engineering design.更多还原
