| 摘 要： | 该文考虑荷载横向分布系数沿跨度的变化，用解析法建立了简支梁桥主梁由车道荷载图式中的集中荷载产生的支点截面最大剪力实用计算公式，避免了通过试算求最大剪力时的麻烦，详细论述了各种情况下主梁支点截面最大剪力的计算方法。同时对车道荷载中的均布荷载产生的支点剪力，也导出了具体计算公式，以便实际应用。最后通过三个算例，详细说明了公式在各种情况下的应用。

| Abstract: | The article considers the variation of load transverse distributing coefficient along the span,sets up the practical calculation formula of the support section of the maximum shear produced by the centralized load in the lane load chart of the main beam of the simple-supported beam bridge using the resolving method so as to avoid the trouble when evaluating the maximum shear through calculation,and discusses in detail the calculation methods of the maximum shear of main beam support section under various co... |
