预制混凝土空心模剪力墙受力性能试验研究
Experimental study on mechanical behaviors of concrete shear wall with precast two-way hollow slabs
摘要
Abstract
One reinforced concrete shear wall and five concrete shear walls with precast two-way hollow slabs were tested under low cycle lateral loading.The mechanical behavior of concrete shear wall with new type precast two-way hollow slabs was studied,where the horizontal slab holes are circular and the vertical ones are rectangular.The study shows that there are vertical cracks appearing along the vertical reinforcement of the precast concrete shear walls.As aresult,the brittle shear failure is avoided.The displacement ductility ratios of the precast shear walls are between 3.87 and 6.47 and deformability is good.It is also proved that the week link is the cast-in and precast concrete interface,which can decrease the shear bearing capacity of precast concrete shear walls,especially for specimens with high axial compression ratio.The stiffness of new-type shear walls during the application stage is similar to that of reinforced concrete shear wall,and the stiffness of new-type shear walls is not reduced when designing the shear walls.Raising the axial compression ratio and reducing shear span ratio can increase the initial rigidity,but accelerate the late stiffness degradation.As the decrease of horizontal reinforcements,the shear capacity and deformability are less affected,and cracking load are reduced,while the crack width is increased.关键词
