These earthquakes also arouse engineers to resurvey the behavior of end-plate connections. It is well known that end-plate connections have definite flexibility, which can increase damp, prolong period, and decease swing of structure.

Steel moment-resisting frames with welded beam-to-column connection were traditionally regarded as having excellent performance, and widely adopted in steel constructions, but this opinion changed after the 1994 Northrige earthquake and the 1995 Hyogoken-Nanbu earthquake. These earthquakes also arouse engineers to resurvey the behavior of end-plate connections. It is well known that end-plate connections have definite flexibility, which can increase damp, prolong period, and decease swing of structure. So it can reduce the damage, and is one of the best choices for resisting earthquake.

中文题名钢框架梁柱端板连接在循环荷载作用下的破坏机理及抗震设计对策副题名外文题名 Collapse mechanism and design criterion of steel beam-to-column end-plate connections under cyclic load 论文作者郭兵导师顾强学科专业结构工程研究领域\研究方向学位级别博士学位授予单位西安建筑科技大学学位授予日期2002 论文页码总数127页关键词钢结构框架结构抗震设计钢框架梁柱端板连接馆藏号BSLW /2003 /TU392 /6 传统观点认为，梁柱焊接刚性连接具有较好的抗震性能，因此在工程中得到了广泛地应用，但1994年的Northrige地震和1995年的阪神地震改变了这种传统观点，这两次地震也引起了工程技术人员对端板连接的再审视。
