T形件连接的梁柱刚性节点性能分析
摘要
T形件连接的梁柱刚性节点在美国和日本有着广泛的应用，然而在我国对这方面的研究并不充分。为此，本文对T形件连接的梁柱刚性节点的性能进行了研究。
首先对受力-变形性能机理进行理论分析，建立相应的简化理论方法。然后，本文在考虑材料、几何和状态三重非线性的基础上，对该连接形式进行了计算机模拟，其主要内容为对所有设计的有限元模拟试件进行计算，分析其结果，找出这种连接的各种破坏形式及M-θ曲线。为设计者提供合理的T形钢梁柱连接设计依据。
Rigid beam-to-column connection with T-stub is widely used in the USA and Japan. As the research of this kind of connection is not enough in our country, this paper mainly discussed the behavior of rigid beam-to-column connection with T-stub.
Firstly, the mechanism of force-deformation was analyzed theoretically. Then the corresponding mechanical model was established. Then a computer modeling using finite element program with material, geometry and state triple-nonlinear taken into account is carried out. The results were analyzed, and various failure patterns and M-curves were derived. According to the results, appropriate design suggestions are given out for designers.
