| 摘 要： | 采用弹性有限元方法,对现浇钢筋混凝土空心板无梁楼盖的计算模型进行分析,给出三种典型区格的弯矩分布和这些区格中柱上板带和跨中板带的板带弯矩及分配系数,与等厚度实心板进行对比,分析了空心管对刚度的影响,提出两向的计算刚度,可以采用实心板无梁楼盖的经验系数法和等效框架法。对于指导工程设计,具有参考价值。 |
| 关 键 词： | 现浇钢筋混凝土空心板 空心板无梁楼板 跨中板带 柱上板带 刚度各向异性 |

| Abstract: | The cast-in-place reinforced concrete (RC) hollow flat slab had been analysed by means of the elastic finite element method.Three kinds of typical panel distribution moment are given out and the strip moment of column strip and middle strip and distribution coefficient in the panels are also obtained.Compared with the equivalent thickness solid flat plate,bi-direction stiffness are proposed taking into account hollow tubes.The experimental coefficient method and the equivalent frame method of the solid flat plate can be used.It is effective for instructing engineering design. |
| Keywords: | Cast-in-place RC hollow slab Hollow flat slab Middle strip Column strip Anisotropic property of stiffness |
