矩形钢管桁架 KT 型加强节点有限元对比分析

摘要

Combining with the engineering example,using the finite element method,from the failure mode,plastic development situation,ulti-mate bearing capacity and other aspects compared and analyzed the domestic stiffening and strengthening node and not stiffening node,the results showed that the stiffening and strengthening way could obviously increase the bearing capacity and stiffness of node,met the needs of practical engineering.%结合工程实例，利用有限元方法，从破坏模式、塑性发展状况、极限承载力等方面，对内加劲加强节点和未加劲节点进行对比分析，结果表明内加劲加强方式能够明显提高节点的承载力和刚度，满足实际工程需要。
