Abstract: In order to better understand the effect of top-bottom angle steel and end-plate connections on the seismic performance of PEC column-steel beam joints, the angle steel thickness, end-plate thickness and column flange thickness were taken as analysis parameters to carry out low-cycle repeated horizontal load tests of six groups of PEC column-steel beam joints, and the failure modes, bearing capacity, hysteretic performance, ductility and consumption of the joints with the two connection modes were compared and analyzed. The test results show that the bearing capacity, hysteretic behavior and ductility of end-plate connections are better than those of top-bottom angle steel, increasing the thickness of top-bottom angle steel can significantly improve the bearing capacity of the joints, with the maximum increase of 19-8%, the hysteretic curves of PEC column-steel beam joints with the action of top-bottom angle steel and end-plate connections are relatively full and show good seismic performance.
Keywords:PEC column; top-bottom angle steel connection; end-plate connection; seismic behavior
