摘要
用Fortran语言编制了梁截面弯矩—曲率关系的分析程序,梁单元采用分布柔度单元,材料采用成熟的本构模型,非线性分析的计算结果与试验结果进行了比较,验证了非线性分析模型的合理性,采用这一计算程序对比分析了混凝土梁加固前、后承载力的变化,提供了粘钢加固后梁的承载力变化的定量指标,可供工程设计参考。
A program is developed for the purpose to analyze the relation of cross sectional moment- curvature using Fortran language. Distribution flexible element is adopted for beam element, while classic relationships between stress and strain for concrete and steel are employed in establishment of analytical model. Accuracy of the analytical model is verified by comparison of the analytical and experimental results. Then, the program is used to analyze the reinforced concrete beam strengthened by steel plate. The quantities of ultimate load-bearing capacity improvement of studied beams are presented after strengthened by steel plate, which are useful for engineering design in future.
