摘要
在模拟裂缝间钢筋应变分布的基础上 ,建立了混凝土梁滑移、裂缝宽度及刚度的统一计算方法 ,并提出了物理概念明确、计算简便的简化设计公式。所建议的计算公式经大量模型梁试验数据验证表明 ,计算公式具有较高的精度。
Based on the simulating steel strain distribution in cracks, this paper establishes a unified computing model for the slip, the crack width and the flexural stiffness in concrete members. In addition, simpler calculating formulas which have a definite physical meaning are presented also in the paper. The formulas recommended are verified with the test data, the results show that the formulas have higher precision.
