| 摘 要： | 根据“强节点,弱杆件”原则对双腹板连接板连接剪切板和梁腹板的梁柱弱轴连接方式进行了有限元分析,探讨了梁柱刚性节点连接部位对接焊缝的断裂机理、节点各板的应力分布、节点破坏状态及抗震性能.提出焊缝应该注意的问题并建议用较合理的连接方式来提高节点受力性能.

| Abstract: | Based on the principle of "strong connection,weak pole" in FEA,the connections which was composed by one shear board weds and two steel boards is analyzed.Them the discussion of the distribution rule,the consumption energy performance and connection destruction form are discussed.We have proposed what should be noticed in welded joints and suggest a reasonable connection position to improve their properties. |
