上海张江路川杨河桥设计及其拱肋受力特征

Design of Shanghai Zhangyang Road Chuanyang River Bridge and Stress Character of Its Arch Rib

该文对上海浦东张江路川杨河桥的总体设计作了介绍。该桥为90 m主跨的钢管混凝土系杆拱桥,为了分析清楚其局部受力,建立了整片拱肋的模型,采用带中间节点的板壳单元和实体单元进行计算。通过计算可以清楚地认识其各部位的应力大小,结果表明结构是安全的。

The article introduces the overall design of Shanghai Pudong Zhangyang Road Chuanyang River Bridge. The bridge is a concrete-filled steel tube bowstring arched bridge with 90-m span. The whole arch rib model is set up in order to analyze clearly its partial stress. The plate shell unit and the solid unit with the middle nodes are used for the calculation. It can be clearly to know the stresses of its positions after calculation. The result makes clear that the structure is safe.
