摘要
采用AN SY S对竖向荷载作用下钢筋混凝土梁板体系中梁板的相互作用关系进行研究分析,通过调整梁板相对刚度α来分析梁的刚度对板弯矩的影响。并且与按静力计算手册查表计算的结果相对照,提出了方形现浇板不同部位的板格各控制点弯矩与α相关的修正系数方程,以修正未考虑α影响的弹性静力计算所得的板弯矩。
By means of finite element analysis software ANSYS, the influence of beam-to-slab relative stiffness on the moment of the slab in RC floor system under the vertical load is mainly investigated. Comparing with the results of traditional method, the coefficient of moments of quadrate slabs locate on various positions about beam-to-slab relative stiffness is brought forward, for revising the results of traditional method without thinking of influenced by beam-to-slab relative stiffness.
