C100混凝土和Q550双钢板组合剪力墙受剪性能研究
Research on shear behavior of C100 concrete and Q550 double steel plate composite shear walls
摘要
Abstract
To study the shear failure mode and bearing capacity of high-strength double steel plate composite shear walls,five scaled-down specimens with a scale ratio of 1∶4,a shear-span ratio of 1.0,C100 concrete and Q550 double steel plates were subjected to quasi-static tests.The effects of steel content ratio,axial compression ratio and stiffener spacing on their shear performance were analyzed.The test results show that the failure mode of all shear walls are compression-shear failure,and the final failure mode is steel web buckling,weld cracking and concrete diagonal crushing.The hysteretic curves of the shear walls are full and spindle-shaped,with peak drift ratios ranging from 1/85 to 1/57 and ultimate drift ratios ranging from 1/64 to 1/32,demonstrating good energy dissipation and deformation capabilities.Moreover,the higher the steel content ratio,the higher the lateral bearing capacity,and the smaller the stiffener spacing,the better the deformation capacity.A refined finite element model was established using the general finite element software ABAQUS,and the simulation results were in good agreement with the test results,with the error range of shear bearing capacity within 12％.Based on the finite element model,the influences of shear-span ratio ranging from 0.75 to 1.25,axial compression ratio ranging from 0.3 to 0.6,web thickness ranging from 3 to 5 mm,wall thickness ranging from 100 to 200 mm and stiffener spacing ranging from 84 to 172 mm on the shear performance of shear walls were studied.Three existing calculation formulas for the shear bearing capacity of steel plate shear walls were collected and compared with the test results.The results show that the existing formulas are conservative when calculating the shear bearing capacity of high-strength double steel plate composite shear walls.关键词
