摘　　要：采用拉压等效与抗弯等效方法将钢桥面板与钢纤维混凝土2部分换算为单一材料的板单元,将钢箱钢纤维混凝土准结合梁桥其它部位用板壳单元或梁单元进行离散处理,由此对该准结合梁桥进行了空间受力计算分析。算例表明,将钢桥面板与钢纤维混凝土两部分换算为单一材料的板单元,其计算结果与实测结果接近。Convert the deck of steel bridge and steel fiber reinforced concrete into board element of single material by the means of tension-compression equivalence and bending resistance equivalence, Discrete treating the other parts of the steel box and steel fiber reinforced quasi-bound beam bridge as shell element or beam element. And then, analyze the special stress of the quasi-bound beam bridge. The calculation example indicates that the calculate result is close to the actual measurement.
