摘要
常见的地下车库顶板结构体系有主梁大板、主次梁楼板、无梁楼盖以及空心楼盖体系等。主梁-柱托-大板体系是地下车库顶板结构体系的一种新尝试,相比其他体系在受力及经济性方面可有一定的优势。采用有限元软件MIDAS对该体系进行初步研究,采用空间杆-弹性板有限元模型对其结果进行对比分析以探寻在工程中的可操作性,给出配筋方式的建议,并与其他常见体系进行经济性对比。
The common roof structure system of underground garage consists of main beam slab,primary and secondary beam floor slab,no beam floor and hollow floor system.The main beam-column cap-large panel system is an underground garage roof structure system of a kind of new attempt,compared to other system can have certain advantage in structural behavior and economy.In this paper,the finite element software MIDAS is used to conduct a preliminary study on the system,and the model of space rod-elastic plate finite element is used to carry out a comparative analysis of the results to explore the operability in the structural design,and suggestions on the reinforcement method are given,and the economic comparison with other common systems is made.
