Title: Experimental investigation and nonlinear finite element analysis on behavior of connections between prestressed steel reinforced concrete beams and concrete-filled steel tubular columns
Abstract: Based on the experiments of connections between prestressed steel reinforced concrete(SRC) beams and concrete-filled steel tubular(CFT) columns under low reversed cyclic loading,the non-linear finite element analysis(FEA) models considering these factors such as material,geometrical and contact non-linearity are established using the software of ABAQUS,and the proposed model is verified very well by the experimental results.Then,parametric analysis are made to investigate the influence of axial compression ratio,prestressing,strength of concrete in the panel zone and thickness of steel tube in the panel zone and so forth on the behavior of the connections.It is found that compression ratio,thickness of the tube in the panel zone are more important to the behavior of the connections.
