摘要:现浇混凝土空心楼盖是一种由空心箱体和现浇梁板组成的新型楼盖体系,具有空间利用充分、自重轻、整体性好等特点。通过对STRAT等设计软件下的无梁楼盖模型进行比较,探讨空心楼盖模型参数的调整、现有规程范围内的设计优化等问题,并以工程实例对其经济性进行论证。关键词:建筑业;空心楼盖;经济指标;经济分析;优化设计Abstract:The cast-in- place concrete hollow floor is a new type composed floor with hollow boxes and cast-in-situ slab,with full utilization of space,light weight,good integrity and other features. The paper through STRAT software contrasts the models of girder-less floor structure,discusses model parameters adjustment,the optimization design in the range of existing specifications,also demonstrates its economy with an example.Keywords:construction industry;hollow floor;economic indicators;economic analysis;optimization design参考文献[1] 周绪红,陈伟,等.混凝土双向密肋装配整体式空心楼盖刚度研究[J].建筑结构学报,2011(9).[2] 郭乐工,郭乐宁,刘成才.预制装配整体式楼盖的技术经济分析[J].建筑经济,2009(9).建筑经济,2014(12):55-58
