| 摘 要： | 为保护古建筑,采用低周反复加载试验方法,以故宫太和殿某开间梁柱尺寸为原型,制作了3组1:8的缩尺比例的4梁4柱模型,考虑榫卯节点形式为燕尾榫,进行了低周反复加载试验,研究了古建筑木构架的抗震性能,获得了构架的P-Δ曲线,分析了构架的骨架曲线、耗能能力、刚度退化及变形能力,归纳了构架恢复力拟合曲线计算公式。结果表明:古建筑木构架的P-Δ滞回曲线为Z形,具有明显的捏拢特性;随着构架侧移增大,其侧移刚度降低,耗能能力趋于稳定;另一方面,构架具有良好的变形能力。

| Abstract: | To protect Chinese ancient building aseismic behaviors of Chinese ancient wooden structure were studied by experiments.Based on actual sizes of some part of Tai-He Palace in the Forbidden City,3 wooden frame models with a scale of 1:8 of the prototype structure were built considering Yan-wei type of tenon-mortise connections.By low cyclic reversed loading tests P-hysteretic curves as well as skeleton curves of the models were obtained;By analysis their energy dissipation capability,stiffness degradation,def... |
