【摘要】 进行了梁拱组合体系边跨钢拱肋与刚性系杆连接部位的局部三位全仿真分析和1:3.2的大比例模型试验,得出了在最不利工况下连接部位的应力分布的一般规律,定量的得到了结构内的应力分布情况,为工程设计和施工提供了合理的依据更多还原

【Abstract】 There have been carried out the local three-dimensional imulation analysis of the side arch rib for beam arch composite hierarchy and the connection for rigid tie bar,and the test of 1∶3.2 model in large proportion,thus the general law for stress distribution at connection in the most disadvantageous behavior has been obtained,and the stress distribution inside structure quantitatively got,which provide the rational basis for design and construction of a project更多还原
