Experimental study on seismic performance of multi-ribbed composite wall-beam supported on frame
摘要
Abstract
Four large-scale models of multi-ribbed composite wall-beam supported on frame structure were tested.The failure process and patterns,bearing capacity,deformation and ductility,hysteretic characteristics,stiffness degradation and collapse-resistant capacity were analyzed in detail.The results show that the failure of multi-ribbed composite wall-beam is primarily due to shear,with high bearing capacity,great ductility and good collapse-resistant capacity.The combination effect of wall-beam is obvious.The main controlling factor of frame beam is the shear capacity of oblique section near the supports.The multi-ribbed composite wall appears to get cracked from infilling blocks to ribbed frame,and then to the outer concealed frame,which is beneficial to ensure the seismic safety of the structure.Columns and beams arranged near the hole can effectively keep the bearing capacity and stiffness constant,while the ductility of the specimen can be reduced.As the bearing capacity and lateral stiffness of multi-ribbed composite wall are relatively high,much more attention should be paid to the arrangement of the stiffness and bearing capacity in the structure,which can be properly resolved by adding multi-ribbed composite wall at the bottom or optimizing the constitution of the wall.关键词
