中文摘要: |
在合理假定的基础上,根据混凝土、钢梁和钢筋的本构关系,利用平衡及变形协调条件,推导出了适用于组合梁受扭全过程分析的一系列方程式,并提出了组合梁受扭分析的简化算法。然后,用VC 6.0编制了分析程序,制作了输入和输出的可视化界面。最后,对实验和理论分析结果进行了对比,结果表明方法合理,精度满足要求。 |
英文摘要: |
Based on reasonable assumptions and consideration of constitutive relation of concrete, steel beam and bar, a series of equations for full-course analysis on torsional performance of composite steel-concrete beams are derived in the paper by using the equilibrium and deformation compatibility conditions. A simplified method of analysis on composite beams subjected to torsion is given. And with VC++6.0, the corresponding program is developed, which provides visual interface for input and output. Comparison between test and predicted results shows that the method proposed in this paper is rational. |
