大底盘建筑组团地下室顶板结构设计探讨

On exploration for roof structure design of basements of large-chassis building group

对大底盘地下室顶板在结构设计中的两种常见做法,从设计、施工、经济三个方面结合实例进行了比较,从而得出对一般的车库顶板而言十字形次梁布置方案比无次梁的主梁布置方案有良好的经济性和结构性能,而无次梁的主梁布置方案在施工进度方面具有一定的优势的结论。

The paper compares the two common ways in the structural design of the basement roof of large-chassis buildings from the design,the construction and the economy,and concludes the cross-shaped secondary beam allocation scheme can have better economical and structural performance than the one of the main beam without secondary beam in the general garage roofs,while the main beam allocation scheme without secondary beam can have certain advantages in the aspect of the construction progress.
