摘要

摘要: 采用纤维模型法编制非线性分析程序,绘制出弯矩-曲率全过程曲线,并与有关文献试验数据进行比较,吻合较好。在此基础上,对混凝土强度、钢骨形式、配骨率、套箍率等因素对抗弯构件力学性能的影响进行分析比较。最后通过对数值计算结果的回归分析,得出实用的抗弯承载力计算公式。

Abstract: Based on theory of fiber model method, a nonlinear analysis of computer program is developed. As compared with experimental data of corresponding documents, the results agree well with each other. Then the influences of strength of concrete, stirrup ratio, stee-l reinforced ratio, changes of shape on the mechanical property of bending members are also analyzed. Through regressive analysis of the results of numerical calculation, a practical formula is got.
