摘要
在恒载作用、温度荷载和活载等因素作用下,连续钢箱弯梁会出现梁内侧支座脱空、梁体向外侧移和翻转等一系列问题,因此,设计难度大。利用有限元建模对工程实例计算,并对结果进行了分析,为今后建造类似工程实践提供了参考。
With impact from constant load, temperature load and dynamic load, the curved continuous steel box girder may cause problems such as the inner side bearing disjointed, the girder moving to the outer side and turning over, so it is difficult to design such bridges. Using FEM to calculate the engineering example and analyze the result, which can be a reference for construction of similar works.
