摘要 通过对钢筋混凝土受弯构件正常使用极限状态计算公式中钢筋应变不均匀系数的分析和研究,建立了钢筋应变不均匀系数的简化计算模型,并推导出简化计算公式,其计算结果与现行规范[1]给定的经验公式的计算结果相当吻合。为现行规范的经验公式提供了一种新的理论计算方法。 Through the analysis and study of non-uniformly distributed strain coefficients of reinforced concrete bending members under serviceability limit state, we build a reduced computation model is set and up a reduced computation formula of steel strain non-uniform coefficients is also deduced. The results are confirmed with the results of the empirical formula in the present standard code. This method offers a new theoretic calculation method for the empirical formula in the present standard code.
