摘要
该文指出:梁格法是一种空间计算的近似方法,具有概念清晰、易于理解等特点,较广泛应用于斜、弯等异型结构梁桥的计算分析。基于梁格法的基本原理,对某钢筋混凝土变宽度曲线箱梁桥进行结构建模,计算分析其在设计荷载及试验荷载作用下结构的静力响应,并根据现场试验结果对结构进行评价。
The article points out that the grillage method is a similar method of space calculation, has the characteristics of clear conception and easy understanding, and is more widely used for the calculation and analysis of the special structural beam bridges. Based on the basic principle of the grillage method, the article introduces the structural modeling of a steel reinforced concrete variable width curve box beam bridge, calculates and analyzes the static response of structure in the design load and test load, and evaluates the structure according to the filed test results.
