| The structure of the frame is prone to the phenomenon of interlaminar yield failure due to the hinge of the column after the earthquake.Although the structural seismic design ensures the deformation resistance of the column and the anti-collapse ability of the frame by strengthening the axial compression ratio,it is difficult to achieve the expected damage to the seismic structure due to the addition of the filled wall to a certain extent mechanism.Therefore,the method of strengthening the axial compression ratio in the current seismic code can not fundamentally solve the problem of anti-collapse of frame structure.Based on the study of the rocking filled wall-frame structure,this paper analyzes the seismic effect of the rocking filled wall-frame structure due to the special design of the wall,the anti-seismic effect and the reduction of the axial compression ratio parameters.The purpose is to analyze the anti-collapse ability of the rocking infilled wall-frame structure.In order to further promote the application of the rocking filled wall-frame structure,this paper designs and the frame structure of a 6-story frame and analyzes the the relationship between the bearing capacity and the ductile structure,the structural damage pattern,the distribution and development of the plastic hinges and the structural arrangement of the rock-filled wall-frame structure are discussed..The results show that the limit of the axial compression ratio can be relaxed by using the structure of the rocking filled wall-frame structure;The rocking filled wall can reasonably control the damage mechanism of the structure,and the deformation of each floor is as uniform as possible to avoid the layer yield mechanism;The stiffness of the ordinary filling wall has a great influence on the "rocking effect" of the rocking filled wall;Rocking filled wall-frame structure is better ductility and has good seismic performance. |
