摘要
介绍了地震区框架下平板基础的内力计算方法。其方法是将平板基础的内力计算方法近似为倒无梁楼盖“等效框架法” ,并假定平板基础的计算单元、板带划分、弯矩及其系数的分配。根据此方法结合具体的设计实例 ,对内力计算的整个过程作了层层分析 ,步步推算。通过工程演算证明 ,该计算方法简便、实用 ,可供设计人员参考。
In this paper the internal force calculation method of flat slab foundation under frame in earthquake area is introduced. Firstly, the internal force calculation method of flat slab follow the ' equivalent frame method ' principle of beamless roof; secondly, the calculation units, division of plate and bending moment coefficient are determined. And combined with design example the whole process of the internal force calculation method of flat slab is analyzed. This method is convenient and applicative, which can provide good references for designers.
