摘要:
型钢混凝土剪力墙是一种广泛应用于高层混合结构中的剪力墙形式。本文采用通用有限元程序ADINA,以边缘构件含钢率为主要参数,对不同剪跨比的几组剪力墙承载力和变形能力进行了分析,并与考虑了剪力墙混凝土等级、轴压比、配筋率和边缘约束指标等参数影响的剪力墙性能进行了比较研究。结果表明,在高层结构中采用较高强度的混凝土是有利的,但剪力墙的轴压比需要严格限制,且墙体配筋率并不是提高其抗震性能的有效手段。在高层混合结构剪力墙中,通过边缘构件设置型钢可有效增加墙体延性,且边缘约束构件的约束指标可取0.32左右。
Abstract:
Steel reinforced concrete shear walls is widely adopted in hybrid high-rise buildings. Based on the steel ratio of boundary element, the seismic performance of steel reinforced concrete shear walls with different aspect ratios is analyzed by using finite element program ADINA. The influencing factors like concrete grade, axial compression ratio, reinforcement ratio, boundary confinement index etc. are also considered for the contrast analysis. The results show that it’s benefit to use the high-strength concrete on the high-rise structures. But the axial compression ratio of shear walls should be limited strictly and the seismic performance of wall can not improved effectively by reinforcement ratio. In the shear wall of hybrid high-rise buildings,the ductility of wall will be increased effectively by setting SRC on the edge components and taking the boundary confinement index to be about 0.32.
