【摘要】 钢管束混凝土组合剪力墙作为主要的抗侧力构件,其抗侧刚度和承载力对钢管束混凝土组合剪力墙的抗震分析有重要作用。对钢管束混凝土组合剪力墙的初始刚度进行了研究,在分析8组试验数据的基础上,提出了钢管束混凝土组合剪力墙初始刚度的理论表达式及钢管束混凝土组合剪力墙承载力的计算方法。结果表明,所提出的初始刚度、承载力的理论公式是精确可靠的,钢管束混凝土组合剪力墙承载力良好。更多还原

【Abstract】 Steel tube-concrete composite shear wall is the main lateral load resisting component,therefore,estimating its lateral-resistant stiffness and bearing capacity plays an important role in the seismic analysis of steel tube-concrete composite shear wall. This paper analyzed the research on the initial lateral-resistant stiffness of steel tube-concrete composite shear wall. Based on analyzing 8 sets of test data,the theoretical expression of the initial lateral-resistant stiffness of steel tube-concrete composite shear wall is presented. The theoretical expression of bearing capacity of steel tube-concrete composite shear wall is derived. The results show that the theoretical expression of the initial lateral-resistant stiffness and the bearing capacity of steel tube-concrete composite shear wall is accurate and reliable,the steel-tube concrete shear wall has a good bearing capacity.更多还原
