摘要
混凝土徐变收缩分析是桥梁结构分析中的基本问题 ,已有多种较成熟的计算方法 .从增量平衡方程出发 ,提出了适合利用现代计算机技术实现的时间自动增量徐变收缩分析方法 ,介绍了该方法的基本原理和特点 .并以正在研制开发的新一代桥梁集成CAD系统 (BRCAD)为背景 ,简要介绍了徐变收缩分析方法在BRCAD系统中的实现 .最后给出了一个逐跨施工连续梁的徐变分析算例 。
The analysis for concrete creep and shrinkage is a common problem in the bridge structural analysis, and there are many popular methods available now. On the basis of the global incremental equation, this paper presents an automatic incremental creep and shrinkage analysis method which is easy to implement by using the modern computer technology, include its principle and features compared with other methods. Taking the development of the new generation of bridge integrated CAD system——BRCAD as the application background. This paper gives a brief introduction to the implementation. An example of the creep analysis for a continuous girder bridge constructed with span by span method is also given to prove its accuracy and practicable.
