轴压比与剪跨比对带约束拉杆双层钢板-混凝土组合剪力墙抗震性能影响研究
Influence of axial compression ratios and shear-span ratios on seismic behavior of composite shear wall with double steel plates and infill concrete with binding bars
摘要
Abstract
To further study the influence of axial compression ratio and shear-span ratio on the seismic behavior of composite shear wall with double steel plates and infill concrete with binding bars,cyclic testing was performed on five scaled specimens.The test result shows that the local buckling occurs at the lower part of the wall before failure,specimen with low shear-span ratio (A =1.0) encounters shear compression failure while those with high shear-span ratios (A =1.5 ～ 2.0) show a typical flexural failure.The test result indicates that the specimens also show good bearing capacity,deformability and energy dissipation under high axial compression ratio and low shear-span ratio.The bearing capacity of the specimens is increased with the increase of the axial compression ratio,however the deformation and hysteretic behavior are reduced.With the decrease of shear-span ratio,the bearing capacity and stiffness of the specimens are rapidly increased,energy dissipation decreased,while the ductility and strength deterioration are not significantly affected by shear-span ratio.关键词
