摘要
对部分外包混凝土组合梁(也称PEC梁)抗弯承载力的几种计算方法进行比较分析,并推荐实用的计算方法。同时,利用MATLAB建立PEC纤维层梁模型,对其静力加载过程进行非线性全过程分析,绘制弯矩-曲率曲线。利用该程序,更改截面几何参数和材料参数,进行模拟分析,获得了六个参数对于PEC梁抗弯承载力、截面延性的影响情况。
Several calculation methods of flexural bearing capacity of partially encased composite beams and （also known as PEC beams） are compared and analyzed in this paper, and a practical calcu- lation method is recommended. Moreover, the PEC section fiber model is established with MATLAB and this model is used to analyze static loading process of PEC beams and the bending moment-curvature curve was obtained. By changing the geometrical parameters and material parameters, the influence of six parameters on the flexural capacity and cross-sectional ductility of PEC beams was obtained.
