某小区地下室顶板结构方案经济性比较

Comparison on the structural scheme economy of the basement roof in the community

以某小区地下室顶板结构布置为例,对十字梁布置、单向双梁布置、井字梁布置三种方案进行了计算分析,并从经济性、结构合理性、配筋等方面对各方案进行了比选,得出"单向双梁为主,结合井字梁"的方案最佳。

Taking the structural distribution of the basement roof in the community as an example,the paper calculates and analyzes three schemes including crossbeam distribution,single-direction and double-beam distribution and caisson beam distribution,compares their economy,structural rationality and reinforcement and so on,and conclude that： the scheme of single-direction and double-beam integrating caisson beam is optimal.
