摘要
采用Midas/GTS有限元软件,对某超长超大的地下空间主体结构进行了考虑地震、温度等各种荷载效应组合的有限元分析,获得了最不利荷载组合作用下结构构件的设计内力值及位移,并校核了位移与层间位移角的规范性,以确保结构设计安全。
Finite element analysis of the main structure of a large and extra-large underground space was carried out by using Midas/GTS finite el-ement software which considered various load effect combinations including earthquake, temperature and other loads. The design internal force value and the displacement of the structural member under the most unfavorable load combination were obtained to calculate the reinforcement and check whether the displacement and the displacement between the layers meet the specification limits. This is done to ensure that the structural design is safe.
