| 摘 要： | 针对《混凝土结构设计规范》(GB 50010-2002)中受弯构件刚度计算公式仅适用于单向受弯这一突出问题,提出用“双向板带叠加法”计算柱支承板板格中心变形的思路和方法。应用有限元分析结果拟合出柱支承板支座控制截面的弯矩最大值Mmax与弯矩平均值-M比值(Mmax/-M)的计算公式,并据此提出柱支承板裂缝验算建议方法。

| Abstract: | In view of the outstanding problem that the stiffness formula of the flexural member in the current"Code for Design of Concrete Structures"(GB 50010-2002) can only be used for one-way flexural member,the two-way slab strip superposition method for calculating deflection in the panel center of flat plate supported by column(FPSC) is presented.The calculation formulas of ratio M-(max)/ of the maximum moment(M-(max)) to the average moment() at the critical section of support of FPSC is given by finite element analysis and curvefitting.Based on the method and formula,recommendatory method on crack check for FPSC is presented. |
