Abstract

In the present study, we conducted out the flexural test of column corresponding to the first story in tigh rise frame consisted of precast concrete syructure, in order to investigate the mechanical behaviors under seismic load. This paper aims at evaluating the ultimate flexural capacity of a precast concrete column connected by grout-filled coupling sleeves for the steel bar with high strength. By using the theory of compressive struts constituted in precast concrete column, the model on tie action and arch action is conducted and its conformity to experimental results is verified.
