摘要
通过大跨度双向钢-混凝土井字组合梁的实际工程应用,结合设计与施工过程应力跟踪检测结果分析,消除了结构设计人员对钢-混凝土组合结构中的支座半刚性节点受力状态的顾虑;同时通过同类结构的方案比选,验证大跨度双向钢-混凝土井字组合梁结构为可持续发展的低碳绿色结构,值得推广应用。
The stress state of the semi rigid nodes at supports in the steel concrete composite structure is a big issue for the structural designers. The objective of the present investigation is to solve this problem through monitoring and analyzing the stress state during design and construction period for a practical engineering project with a long-span bidirectional steel-concrete shape composite beam. Through the comparison of different structural schemes for the same structure, it is proved that the long-span bidirectional steel concrete shape composite beam structure is a kind of low-carbon green structure which is suitable for sustainable development.
