摘要
以某三跨24层巨型框架结构为例,采用通用有限元软件SAP2000,对比分析了巨型框架结构梁柱节点为刚接、铰接、半刚性连接的自振周期、位移与前三阶振型下的连梁轴力。探讨了考虑梁柱半刚性连接巨型框架受力性能,提出了合理化建议以指导工程实践。
The results of a 24-story mage-frame structure with 3 span was calculated by the universal finite element method of SAP2000, the different structural characteristic values such as structural free vibration periods, structural displacements and axial forces under the first three vibration modes were compared. Behaviors of mega-frame structures considering semi-rigid connection between beam and column were discussed, and some reasonable suggests were put forward for use in engineering practice.
