摘　　要：为提高杆系模型的分析精度,以一V墩刚构桥为工程背景,以实体模型结果为判断标准,根据主梁与斜腿交点位置的不同建立了2种杆系单元有限元模型并进行了分析.研究结果表明:建立V墩刚构桥midas civil模型时,将拱肋上部作为主梁的一部分进行建模结果更接近实际受力状态.In order to improve the analysis accuracy of the pylon model, a V-shaped rigid frame bridge is taken as the engineering background, and the results of the solid model are used as the criteria. Based on the difference in the intersection point between the main beam and the inclined leg, two kinds of rod element finite element models are established and analyzed. It is shown that when the midas civil model of the the V-shaped rigid-framed bridge is established, the upper part of the arch rib is modeled as part of the main beam could get a result closer to the actual stress state.
