【摘要】：超高层剪力墙应该具备承载力大、抗震延性好、易于施工等特点。姚攀峰提出了多腔钢管钢筋混凝土剪力墙,为巨型结构的剪力墙提供了一种有效的解决方案,并在天津高银117超高层项目中得到了应用,但是尚缺乏深入的研究。以天津高银117项目中多腔钢管钢筋混凝土剪力墙为基础,通过有限元分析等技术手段,初步探讨了多腔钢管钢筋混凝土剪力墙的力学性能,该剪力墙的受拉、受压承载力强轴抗弯承载力与内置钢板钢筋混凝土剪力墙比较接近,略有提升,延性和防倒塌能力有一定提高;该剪力墙的弱轴抗弯承载力、抗扭承载力较与内置钢板钢筋混凝土剪力墙差异较大,有大幅度提升。结果可进一步推广到其他类型的钢管钢筋混凝土剪力墙。
[Abstract]:High-rise shear walls should have the characteristics of large bearing capacity, good seismic ductility and easy construction. Yao Panfeng put forward the multi-cavity reinforced concrete filled steel tube shear wall, which provides an effective solution for the huge structure shear wall, and has been applied in Tianjin Gaoyin 117 super high-rise project, but it is still lack of in-depth research. Based on the multi-cavity reinforced concrete filled steel tube shear wall in Tianjin High Silver 117 Project, the mechanical properties of the multi-cavity reinforced concrete steel tube shear wall are preliminarily discussed by means of finite element analysis, and the tensile strength of the shear wall is also discussed. The flexural capacity of the compressive bearing capacity is close to that of the steel plate reinforced concrete shear wall, and the ductility and anti-collapse ability of the shear wall are improved to a certain extent, and the weak axial flexural capacity of the shear wall is improved. The torsional bearing capacity is much higher than that of the inner steel reinforced concrete shear wall. The results can be extended to other types of steel tube reinforced concrete shear walls.
