    摘要:

    以盐城广播电视塔实际工程中剪力墙的构造形式为基础,通过九个缩尺试件,研究不同构造形式的双层钢板内填混凝土组合剪力墙在常轴力和反复水平荷载作用下的刚度变化特征、破坏机理与破坏模式、抗震性能和极限承载能力.分析了墙板的高宽比、轴压比、钢板厚度、混凝土强度等级等对双层钢板内填混凝土组合剪力墙受力性能的影响.结果表明:双层钢板内填混凝土组合剪力墙能够充分发挥钢板与混凝土材料各自的优点,是一种良好的抗侧力构件.

    Abstract:

    A case study was made of Yancheng Radio and Television Tower to investigate about the variation characteristics of stiffness, failure mechanism and failure mode, seismic performance and ultimate load bearing capacity of double steel layer concrete composite shear walls with different construction forms under constant axial forces and repeated horizontal loading on the basis of 9 scaled test models. An analysis was also made of the influence of height width ratio, axial compression ratio, plate thickness, concrete strength grade of the wall on the double steel layer concrete composite shear walls. The test results show that the the double steel layer concrete composite shear wall can make full use of steel and concrete, which is a structural member with better lateral resistance.
