Experimental Study on Seismic Behavior of Partially Encased Concrete Column-Steel Beam Frame Connected with Top and Seat Angles
摘要
Abstract
In this paper,three frames of partially encased concrete column-steel beam are designed in order to study the seismic performance of partially encased concrete column-steel beam frames connected with top and seat angles.The key parameters are the vertical distance between the centers of the bolt holes in vertical limb and the horizontal limb of the angles and the axial compression ratio.Three frames are tested under low frequency cyclic load,and their seismic behavior indexes are analyzed.The results show the failure sequence of frames follows the seismic design principle of strong column and weak beam.Proper increase of the axial compression ratio or decrease of the angle bolt margin canimprove bearing capacity and initial stiffness of the frame.The frames have good hysteresis behavior,and the ductility factor satisfies the Code for Seismic Design of Buildings.In conclusion,this abovementioned frame has good seismic performance.关键词
