剪力墙结构中可更换钢连梁的抗震性能研究
发布时间：2021-04-23 20:55
近几十年来,为了提高剪力墙结构的震后损伤修复能力,人们针对连梁构件提出了多种构造做法,以增加其耗能性能和可更换性能。可更换耗能连梁具有良好的刚度、承载力和耗能能力,但对其合理的抗震设计方法仍然缺乏深入研究。因此,本文考虑钢结构连梁中弯矩和剪力的比例,设计了不同翼缘宽厚比和腹板高厚比的连梁,通过数值模拟分析,研究了它们的抗震性能。主要研究内容如下:（1）介绍了剪力墙结构中可更换钢连梁的设计方法,考虑影响连梁抗震性能的多个关键参数,设计了四组连梁形式。（2）采用ABAQUS有限元分析软件对钢连梁进行受力分析,提出了一种精确有效的数值模拟方法,并通过已有文献试验结果对所用方法的有效性进行了验证。（3）考虑板件宽厚比和加劲肋间距等因素,对连梁的抗震性能进行分析,比较了剪切屈服和弯曲屈服模式时连梁应力分布特点和滞回耗能能力。（4）依据所定义的连梁弯矩-剪力比例参数,给出了连梁发生剪切屈服和弯曲屈服的临界范围;得到了板件宽厚比和加劲肋间距对连梁刚度退化和耗能系数的影响规律;基于分析结果,提出了改进连梁抗震性能的意见和建议。
