摘　　要：针对活性粉末混凝土预应力叠合梁的受弯性能,利用有限元分析软件ANSYS,建立了活性粉末混凝土预应力叠合梁的三维有限元数值分析模型,对试验全过程进行了仿真模拟,并研究了主要参数(如:有效预应力,后浇层混凝土强度等级,后浇层纵向配筋率等)对叠合梁受弯性能的影响,为活性粉末混凝土预应力叠合梁的设计提供了参考。The three-dimesional models of reactive powder concrete prestressed composite beams were established by the finite element analy- sis software ANSYS in order to research the bending performance of reactive powder concrete prestressed composite beams.The test process of re- active powder concrete prestressed composite beams was simulated and it＇s main parameters that affecting the bending performance, such as the effective prestress, the concrete strength grade of post-cast layer and the reinforcement ratio of post-cast layer, were analysed, the design references for reactive powder concrete prestressed composite beams can be provided by them.
