建筑技术ArchitectureTechnology第54卷第4期2023年2月Vol.54No.4Feb.2023·388·小区地下车库无梁楼盖方案比选与设计建议王川(北京市建筑工程设计有限责任公司,100032,北京)摘要:通过某两限房工程,对地下车库的无梁楼盖及梁板结构(主梁+大板)两种楼盖结构形式进行经济性对比,计算出两种结构形式的构件尺寸和层高差异,统计出了两种楼盖体系的综合经济指标差异,得出无梁楼盖体系经济性优于主梁加大板体系的结论。对地下车库无梁楼盖结构设计中的问题进行了总结与归纳,对如何考虑水平地震力对无梁楼盖的影响、是否应该设置暗梁、如何按照GB50011—2010《建筑抗震设计规范》进行防脱落验算、无梁楼盖设计说明中应增加的特殊要求等问题提出具体的设计建议。关键词:无梁楼盖;经济性;抗震设计中图分类号:TU74文献标志码:A文章编号:1000–4726(2023)04–0388–04THEsElEcTioNoFsTrucTurEANDDEsiGNsuGGEsTioNsoNFlAT-slABFloorsTrucTurEoFuNDErGrouNDGArAGEWAnGChuan(BeijingArchitectural&EngineeringDesignCo.,Ltd.,100032,Beijing,China)Abstract:Inthispaper,theeconomiccomparisonismadeoftwotypesoffloorstructurebetweentheflat-slabfloorstructureandthebeamplatestructureintheundergroundgarage,takingatwo-limithouseasanexample.Themeasurementsofcomponentsandtheheightdifferencearecalculatedbetweenthetwostructuralforms,andthedifferencesincomprehensiveeconomicindicatorsofthetwofloorsystemsisanalyzed.Itisconcludedthattheflat-slabfloorisbetterthanthebeamplatestructureeconomically.Theproblemsinthestructuraldesignoftheflat-slabfloorintheundergroundgaragearesummarized.Somespecificdesignsuggestionsareputforwardforaseriesofproblems,suchashowtoconsidertheinfluenceofhorizontalseismicforceontheflat-slabfloor,whethertoinstallinnerbeams,howtochecktheanti-fallingcalculationaccordingtotheGB50011—2010CodeforSeismicDesignofBuilding,andthespecialrequirementsshouldbeaddedinthedesignnotes.Keywords:flat-slabfloor;economicalefficiency;seismicdesign近年来,城市中各个新建小区,为了保证绿化率、停车位配比,配建人防面积以及地上人车分流提高建筑品质的需要,均建造与主楼连为一体的大型地下车库,通常为地下1层或2层。由于拿地等成本高涨,建设单位对建安成本控制越来越重视,...
