The influence of connectors on the seismic performance of precast assembled CFST columns
The finite element model of seismic performance of concrete-filled steel tube (CFST) column with bolted connection is firstly established in this paper, and the accuracy of the model is verified. Furthermore, the numerical simulation of bolt-connected precast assembled CFST column with inner steel tube is carried out based on the finite element model. Finally, the influence mechanism of bolt number and flange thickness on the seismic performance of precast assembled CFST column with inner steel tube is studied according to the result of finite element analysis. The research can provide theoretical support for the optimal design of CFST.
