摘要
介绍了美国北岭地震与日本阪神地震后钢框架新型延性节点的发展状况。对4种不同构造形式的箱型柱钢框架梁柱节点进行了ANSYS非线性有限元分析,求得其应力发展状况,应力分布以及框架塑性铰出现的顺序。对节点的力学性能进行了分析比较,重点讨论了削弱型节点的研究进展。基于理论分析,提出了改进型节点。
During the Northridge earthquake and Kobe earthquake, the typical beam-column moment connection in steel moment-resisting frame suffered unexpected brittle failures. By using ANSYS the nonlinear FEM four different types of connections with different details are analyzed . The conditions of stress development, the distribution of stress and the appearing orders of plastic hinges of this type steel frame under loading were analyzed. And the mechanical behaviors of the different connections are analyzed and compared. The performance on steel moment connections with reduced beam or web sections is addressed. The connection with modified detail is presented based on the results of the analysis
