钢纤维混凝土双肢剪力墙抗震性能试验
Experiments on Seismic Behavior of Steel Fiber Concrete Coupled Shear Walls
摘要
Abstract
One reinforced concrete coupled shear wall and two steel fiber reinforced concrete coupled shear walls with different steel fiber volume fractions were tested under horizontal low frequency cyclic loading. According to the measured test data, hysteretic curves and skeleton curves of shear walls were drawn. Ductility coefficient, stiffness and energy dissipation factor of shear walls were calculated. Effect of steel fiber volume fraction on seismic performance of coupled shear walls was studied. The rule of ductility, stiffness and energy dissipation with different steel fiber volume fractions was analyzed. Experimental and analytical results showed that compared with reinforced concrete coupled shear wall, yielding stiffness and limit deformation were increased by steel fiber, bearing capacity of steel fiber reinforced concrete coupled shear wall was enhanced, hysteretic curve was plumper, displacement ductility coefficient and stiffness and energy dissipation were increased dramatically with the raising of steel fiber volume fraction. Seismic performance of reinforced concrete coupled shear wall had significant improvement.关键词
