摘　　要：运用钢筋和混凝土的应力 -应变关系、几何条件和平衡条件 ,用条带法实现积分 ,对预应力混凝土叠合梁进行电算分析 ,计算结果基本能够反映预应力混凝土叠合梁的两阶段受力特征。In this paper,the prestressed concrete superposed beam is analysed by means of strips method and using matlab language,in which the stress-strain relations of concrete and bar,geometrical conditions,equilibrium conditions are considered.The results basically embodies the behavior of the prestressed concrete superposed beam loaded by two stages.

关 键 词：预应力混凝土叠合梁 条带法 电算分析 应力-应变曲线
