公路桥梁荷载横向分布计算的模型修正法研究

Study on Model Correction for Highway Bridge Load Lateral Distribution Calculating

桥梁结构属于空间结构,结构的内力计算通常是转化为平面问题来解决的。介绍了几种常用的荷载横向分布计算方法。针对桥梁运营后,桥梁各片主梁刚度不同时的荷载横向分布计算,提出了更加符合桥梁实际的模型修正法,更为准确地计算实际桥梁结构各片主梁的荷载横向分布系数。

The bridge structure is spatial structure ; the internal force calculation of the structure is usually trans- formed into a plane question. This article describes several common lateral load distribution calculation methods. After bridge operation, for the calculation of lateral load distribution with different stiffness of each main beams, model correction method has been put forward, which is much more in line with the actual conditions of the bridge, more accurate calculation of the lateral load distribution factors of each main beams of the actual bridge structure can be conducted.
