【摘要】 为改善强震作用下超高层结构底部剪力墙的抗震性能,内置钢板钢筋混凝土组合剪力墙结构体系在实际工程中得到了越来越多的应用。基于OpenSees程序的模拟分析,对比试验结果表明该分析方法能够较好地模拟钢板组合剪力墙的弹塑性行为,分析了轴压比、配钢率和剪力墙配筋率三个参数对内置钢板组合剪力墙抗震性能的影响。计算结果表明,和普通剪力墙相比,内置钢板对于提高构件的承载力、延性和滞回耗能十分明显。轴压比和配钢率是影响组合剪力墙抗震性能的主要因素。虽然剪力墙配筋率对组合剪力墙抗震性能影响很小,但需要一定的配筋率以保证混凝土对钢板有充分的约束作用。更多还原

【Abstract】 To improve the seismic performance of shear walls located on the bottom zone of super high-rise buildings,the steel plate-reinforced concrete com- posite shear wall(SPRCW) has been used in practice engineering increasingly. Comparison of the test results indicated that inelastic behavior of the SPRCW can be described well by the numerical analysis based on OpenSees.The primary parameters varied in the axial load ratio,the ratio of steel plate and the ratio of web reinforcement in RC shear wall.Numerical analytical results indicate that,compared with the conventional RC shear walls,SPRCW has an evident improvement in the lateral load carrying capacity,ductility and energy dissipation capacity.In addition,the axial load ratio and the ratio of steel plate have more significant effects on the ductility and carrying capacity.The ratio of web reinforcement of RC wall has negligible effects on the component performance,but it would be still required to confine the concrete providing lateral support to the embedded steel plate.更多还原
