摘　　要：研究了有粘结预应力混凝土梁中各参数对其弯矩-曲率关系的影响。通过有限元方法对不同参数的有粘结预应力混凝土梁进行求解,可得到相应的弯矩-曲率关系。结合理论分析,并针对力筋偏心距对弯矩-曲率曲线的影响,得出便于运用的三折线简化模型。The influence of several parameters of bonded prestressed concrete beams on its momentcurvature relationship is researched. Through carrying out FEM analysis of bonded prestressed concrete beams with different parameters, the corresponding moment-curvature relationship can be got. Subsequently a simplified trilinear model is obtained specially for the influence of eccentricity combining with theoretical derivation, which is convenient to be used.
