摘要
现浇钢筋混凝土空心板无梁楼盖是无梁楼盖的一种新形式,它是在板中埋设非抽芯式空心管,形成封闭空腔的钢筋混凝土板。对于支承在方形柱网上的无梁楼板,其受力特征表现为板的整体抗弯将在两个正交方向同时和同样地出现。等代空间框架法,即将各层结构平板分别按纵、横方向,划分为由若干纵向与横向梁组成的交叉梁系,与柱子形成空间框架。在采用SATWE软件分析无梁楼盖结构时,由于SATWE软件具有考虑楼板弹性变形的功能,可以采用弹性楼板单元较为真实地模拟楼板的刚度和计算变形。
Reinforced concrete hollow floor without beam is flat floor slab of a new type,which is embedded in the board non-pulling hollow tube to form a closed cavity reinforced concrete slab.For supported on square columns online without beam,its force characteristics of the overall performance of plate bending in two orthogonal directions simultaneously and similarly appears.The equivalent frame method,the structure is flat layers respectively longitudinal and transverse directions,divided into a plurality of longitudinal and transverse beams composed of cross beam system,and pillars form a space frame.In using software analysis SATWE hollow flat slab,due to the floor SATWE software has to consider elastic deformation features,you can adopt a flexible floor unit is more realistic simulation of slab stiffness and deformations.
