波形钢板剪力墙结构性能研究
发布时间：2020-10-19 10:10
钢板剪力墙是由梁和柱围绕内嵌钢板组成的一种核心结构体系。以往的研究已经证明,钢板剪力墙结构在多层或高层建筑中可有效抵抗风或地震引起的侧向力。近期,美国、加拿大和日本的一些主要建筑使用钢板剪力墙作为主要的抗侧力系统。由于钢板剪力墙屈曲载荷很低、对框架附加拉力高、滞回曲线捏缩等缺点,因此,本文提出了一种作为创新性抗侧力系统的波形钢板剪力墙。本研究通过有限元软件ANSYS 13.0进行大量的数值分析,研究波形钢板剪力墙的结构性能,以验证波形钢板剪力墙相对于普通平面钢板剪力墙的优点和缺点。然后比较了不同形式的波形钢板剪力墙的结构性能,以找出如何确定波形板的几何尺寸和周围框架的刚度等参数组合,以实现波形钢板剪力墙体系的良好性能。考虑诸如几何缺陷、高厚比、波幅比、高跨比、周围框架刚度和框架的竖向压缩等参数,进行波形钢板剪力墙的单调加载。得到的结果表明,在选择适当的高厚比,高跨比和波幅比等参数的情况下,可以保证波形钢板剪力墙的抗侧荷载—位移曲线的稳定性,最大承载力接近完全屈服剪切力。由于波折的特征,与普通钢板剪力墙相比,梯形波形钢板剪力墙和正弦波形钢板剪力墙对周围框架的刚度要求低很多。正弦波形钢板剪力墙和梯形波形钢板剪力墙的比较表明,前者在初始刚度和抗侧能力上都比后者有更好的性能。研究结果为波形钢板剪力墙的设计提供了建议,并有助于了解波形钢板剪力墙的结构性能。
