摘要
根据12根肢宽厚比分别为4∶1、5∶1和6∶1的宽肢L形和Z形截面柱在低周反复荷载作用下的试验研究,研究了肢宽厚比大小、箍筋配筋率对构件破坏形态以及极限荷载的影响,分析了以上因素对L形截面和Z形截面柱耗能能力和延性的不同影响,在分析试验结果的基础上提出了异形柱抗剪强度建议计算公式,最后给出了若干工程设计建议。
According to the experimental research on wide flange L shaped and Z shaped section columns with different flange width/thickness ratios(4∶1, 5∶1, 6∶1), the effects of flange width/thickness ratio and stirrup ratio on the failure mode and critical ultimate strength have been studied. The different effects of the above mentioned factors on the energy dissipation and ductility have been analyzed.Meanwhile, the formula for computing shear strength of specially shaped section columns as well as some suggestions for engineering design are also presented in this paper.
