| 摘 要： | 在以往试验研究的基础上,建立了框架异型节点等效核心区在剪、压复合作用下的计算模型,应用简化拉压杆模型方法对等效核心区进行了受力分析.研究表明:基于简化拉压杆模型方法计算得到异型节点的抗剪承载力与现行规范建议方法计算结果相当,但简化拉压杆模型方法有明确的力学计算模型,基于该模型计算得到的抗剪承载力与试验结果吻合较好.在此...

| Abstract: | Based on the experimental study,an analytical model for equivalent joint core of frame joint under the combined action of axial load and shear is established,and the shear strength of equivalent joint core of tested specimens is calculated by using softened strut and tie model(STM).Results indicate that the calculated shear strength of STM is quite nearly with that of code method,but STM has more definite mechanical model.Thus,full agreement between experimental results and prediction results of STM is reac... |
