楼盖建筑结构重要组部混凝土楼盖造价占整土建总造价近30％其自重总重量半左右选择合适楼盖设计案并采用确合理进行设计计算于整建筑结构都具十重要作用
混凝土楼盖设计于建筑隔热、隔声建筑效直接影响于保证建筑物承载力、刚度、耐久性及抗风、抗震性能起着十重要混作用
建筑结构结构组：楼盖建筑结构水平结构体系与竖向构件、抗侧力构件起组建筑结构整体空间
结构体系楼面竖向荷载传递至竖直构件并水平荷载（风力、震力）传抗侧力构件根据同类楼盖同类别
按施工楼盖现浇楼盖、装配式楼盖、装配整体式楼盖
现浇楼盖整体性具较抗震性能并且结构布置灵适应性强现场浇注养护
比较费工工期相应加我规范要求高层建筑宜采用现浇楼盖近由于商品混凝土、混凝土泵送工具模板广泛应用现浇楼盖应用逐渐普遍
装配式楼盖由预制构件装配便于机械化产施工缩短工期装配式楼盖结构整体性较差防水性较差便于板洞用于结构简单、规则工业建筑
装配整体式楼盖由预制构件装配现浇混凝土面层或连接部位构整体兼具现浇楼盖装配式楼盖部优点施工按结构形式楼盖单向板肋梁楼盖、双向板肋梁楼盖、井式楼盖、梁楼单向板肋梁楼盖与双向板肋梁楼盖见楼盖结构板肋梁楼盖由板及支撑板梁组梁通双向交布置板划
矩形区格形四边支撑连续或单块板受垂直荷载作用四边支撑板其两向均发弯曲变形同板荷载传递给四边支撑梁弹性理论析结表明四边支撑矩形板、短边比值较板荷载主要沿短边向传递沿边向传递少面近似析说明该现象现沿板跨两向别切单位宽度板带两根简支梁
根据板跨变形协调条件：
向板带换算截面惯性矩
两向配值忽略两向配筋同影响简化计算、短边比值较板忽略荷载沿边向传递称其单向板；、短边比值较板
四边支承板荷载传递称其双向板工程设计按单向板计算；宜按单向板计,按双向板计算
板肋梁楼盖结构布置灵施工便广泛应用于各类建筑
井式楼盖：结构采用形或近似形（采用三角形或六边形）板格两向梁截面相同主梁其特点跨度较具较强装饰性用于公共建筑门厅或厅
梁楼盖：设梁板直接支撑柱通柱顶设置柱帽提高柱顶处平板冲切承载力及降低弯矩设梁增建筑净高故用于空间利用率要求较高冷库、藏书库等建筑
按否预加应力楼盖普通钢筋混凝土楼盖预应力混凝土楼盖
预应力混凝土楼盖具降低层高减轻自重；增楼板跨度；改善结构使用功能；节约材料等优点适应间、柱网、空间要求、高层及超高层建筑主要楼盖结构体系预应力混凝土结构粘结预应力混凝土粘结预应力混凝土结构两种预应力混凝土楼盖结构采用粘结预应力混凝土结构
新楼盖结构体系：楼盖结构自重占整结构自重比例发展新楼盖结构体系减轻楼盖结构自重直工程技术员努力目标随着近建筑技术蓬勃发展及新材料、新工艺广泛运用传统楼盖体系基础涌现许新楼盖结构体系：密肋楼盖单向双向密肋楼盖密肋楼盖视实板挖凹槽省受拉区混凝土没挖空部梁或称肋柱顶区域般保持实起柱帽作用柱间板带都实柱网轴线形暗梁
扁梁楼盖：降低构件高度增加建筑净高或提高建筑空间利用率楼板水平支承梁做宽
扁形式像放倒梁
现浇空板梁楼盖种由采用高强复合薄壁管现浇孔空楼板暗梁组楼盖减轻结构自重增加建筑净高通风、电器、水道管道布置便具较综合效益
预应力空腹楼盖种由、薄板连接于其用保证、层板共同工作短柱所组
结构、层板预应力混凝土平板或带肋平板结构具截面效率高、重量轻等特点预应力空腹楼盖种综合经济指标较、满足跨度需要楼盖结构
预应力混凝土框架扁梁楼盖：混合配筋预应力混凝土框架扁梁楼盖利用扁梁柱形框架具减结构层高
