【摘要】 两边连接钢板组合剪力墙中的钢板仅与框架梁连接,因此对柱不产生附加弯矩,更符合强柱弱梁的抗震设计原则.本文采用 ANSYS 有限元程序对两边连接钢板组合剪力墙进行模拟.研究预制混凝土板厚度 t_c、混凝土强度等级、钢板的高厚比λ和跨高比β对两边连接钢板组合剪力墙抗剪静力性能的影响,分析其受力机理和破坏模式.研究结果表明,预制混凝土板的厚度、高厚比λ和跨高比β是影响钢板组合剪力墙抗剪静力性能的主要因素,而预制混凝土板的混凝土强度等级对钢板组合剪力墙抗剪静力性能影响很小.更多还原

【Abstract】 Two-side connected steel-concrete composite shear wall’ s (SCSW) steel plate are only connected with beams,and the other two sides are free.In this way,these will be no additional moments in columns,and it accords with the aseismatic principle of"strong column and weak beam".In this paper the research on shear resistance behavior of two-side connected steel -plate shear wall (SPSW) was carried out by using the finite element software,ANSYS.The parameter study is performed on the shear resistance behavior of two-side con- nected SCSW.The parameters include thickness of precast concrete plate t_c,strength of concrete,depth-thick- ness ratio A and span-depth ratio β of steel plates.The performance and failure modes of the steel plates are in- vestigated.The analysis indicates that the thickness of precast concrete plate,depth-thickness ratio and span -depth radio are main parameters,and the strength of concrete is not the main one.更多还原
