摘　　要：建立了无粘结预应力混凝土(UPPC)异型板梁非线性有限元模型,通过有限元模型计算结果与实验数据进行对照,验证了模型的正确性。对所建模型进行了加载全过程的仿真计算,得到异型板梁的极限承载力,并分析了加载过程中跨中截面内外侧受力性能的不同。Nonlinear finite element model of unbonded prestressed concrete（UPPC）special-shaped slab beam is established. The simulation results were compared with the experimental data, by which the correctness of the model is proved. In order to obtain ultimate bearing capacity, the full course simulation was conducted, and the load in and outside the inter-section is analyzed.
