钢框架梁柱节点连接方式的介绍与分析
|
摘要
通过介绍与分析美、日两国在诺斯里奇和阪神地震后研究的钢框架梁柱节点连接方式与施工方法 ,总结出两国梁柱节点的改进措施虽不同 ,但其目的都是为了避免地震时梁翼缘与柱翼缘焊接部位的开裂 ,并提出了选择梁柱节点连接方式的设计建议 ,供参考。
The retrofit research work on the design and construction of the steel frame beam-to-column connection,which were practiced respectively in U.S. and Japan after the Northridge earthquake and the Hyogoken-Nanbu earthquake,is introduced and analyzed.Although the improvement measures of two countries are different,their goals are to aviod the welding spot crack on the joint between the beam flanges and the column flanges under the seismic load.Some reasonable advices are presented for design reference.
