摘要:
为实现框架结构的震后性能快速恢复,提出一种带可替换开缝钢板阻尼器的新型性能可恢复摇摆柱(简称IRR柱),对IRR柱柱底承台在承载力极限状态下局部压应力的分布规律开展研究.采用ABAQUS软件建立精细化的IRR柱有限元模型,研究轴压比、钢板阻尼器厚度等参数对柱底承台局部压应力分布的影响规律,并提出相应的计算方法.研究结果表明:文中提出的计算方法能够较为合理地计算IRR柱柱根承台局部压应力值,且IRR柱的局部压应力大小随着轴压比和阻尼器厚度的增加而显著增大.
Abstract:
In order to achieve the rapid recovery of the post-earthquake performance of the frame structure, a innovative resilience rocking column(referred to as IRR column)with replaceable slit steel dampers is proposed. To study the distribution of local bearing stress at the foundation of IRR columns, using ABAQUS software to establish refined finite element model of IRR columns, and the effects of axial compression ratio, steel damper thickness and other parameters on the local bearing stress distribution of the foundation of IRR columns were studied respectively, and corresponding calculation methods were proposed. The results show that the calculation method proposed in this paper can reasonably calculate the local bearing stress of the foundation of IRR columns, and the local bearing stress of the IRR column increases significantly with the increase of axial compression ratio and steel damper thickness.
