| 摘 要： | 考虑木结构节点的半刚性特性,推导了半刚性框架在侧向力作用下的刚度计算公式,讨论了节点半刚性对框架内力分配的影响.对3榀单层单跨梁柱式木框架足尺试件进行了水平荷载试验,其中1榀为单调加载,2榀为低周反复加载;对5个采用相同设计的梁柱节点足尺试件进行了抗弯性能试验,其中3个为单调加载,2个为低周反复加载.根据试验现象研究了螺栓连接木结构梁柱框架的抗侧力性能、梁柱节点的抗弯性能以及两者的传力机理和破坏模式.最后,基于获得的试验数据对推导的理论公式进行了验证.

| Abstract: | A structural analysis was conducted on semi-rigid timber portal frame; formulas were derived in terms of the internal force and lateral stiffness, and the influence of the semi rigid joint was discussed. Meanwhile, experimental tests were carried out on three full scale timber portal frames and five bolted timber connections to study the lateral performance of the frames and the moment resistance of the connections. For consistency, the connections from the portal frames and the connections for bending tests were of the same configuration. Finally, a comparative analysis was made to verify the derived formulas. |
