蜂窝式钢框架结构抗震性能试验研究
|
摘要
该文通过低周反复荷载试验对蜂窝式钢框架抗震性能进行研究。分析其在地震作用下的受力过程、破坏形式、滞回曲线、骨架曲线、刚度退化、延性等抗震性能。分析结果表明:蜂窝框架在地震作用下有较好的抗震能力,结构的破坏特征主要体现在蜂窝梁上;通过腹板开孔削弱可以控制梁端塑性铰形成位置,使得最大塑性区移至梁腹板削弱处,减小了梁柱连接处的转角,能有效的避免梁柱连接焊缝的脆性断裂,提高了钢框架结构的延性。
This article made the research on the cellular steel frame aseismic performance through a low cyclic loading test.The stress process and failure modes,hysteresis curve,skeleton curves,stiffness degradation,ductility and other behavior of the framework under earthquake effects were analyzed.The results showed that the cellular frame had a good aseismic capacity,and structural damage characteristics were mainly embodied in cellular beams,and the position of plastic hinges on the beam could be controlled through the weaken beam webs,which made the biggest plastic zone move to the weaken place of the beam and reduced the corner of beam-column joint areas as well as could avoid brittle fracture of the beam-column weld and improved the ductility of a steel framed structure.
