摘　　要：通过ANSYS有限元分析软件,建立了两跨预应力钢-混凝土组合结构连续梁的非线性分析模型,通过变换组合梁的高度和各钢板的厚度等参数分析梁的应力、挠度的变化等,综合比较分析腹板高度,底板厚度,腹板厚度,顶面板厚度和混凝土板厚度等因素对组合梁的影响并得出对梁的应力和挠度影响强弱依次为:腹板高,混凝土板高,腹板厚,底板厚和顶板厚。By the FEA software of ANSYS, two cross prestressed composite continuous beam nonlinear analysis model was established. Through change composite beam highly and various steel plates parameter and synthesis com- parison influences of web plate altitude, ledger wall thickness, web plate thickness, kneading board thickness and concrete slab thickness on the structure and get influence composite continuous beams stress and deflection each factor from strongly to weak is： web plate high, concrete slab high, web plate thickness, the ledger wall thickness and the roof thickness.
