摘要
Matlab提供强大的矩阵运算功能和丰富的工具箱,同时具有编程语言简单和易于掌握的特点,可提高工程设计人员的编程效率,蒙特卡罗法是进行结构可靠度分析的重要方法之一。先论述蒙特卡罗法的基本内容,其次介绍其在Matlab环境下的实现方法,接着阐述施工可靠度的定义及其评判桥梁施工质量的基本原理。最后以25m后张法预应力混凝土连续T形梁为例,介绍Matlab实现蒙特卡罗法在T梁施工可靠度中的应用。
Matlab has a strong matrix operation function and abundant toolboxes,and has the features of simple programming language and easy to understand,which can improve the programmer′s programming efficiency.Monte Carlo method is one of important methods for structural reliability analysis.Firstly,the basic content of Monte Carlo method is discussed.Secondly,the implementation of Monte Carlo method by Matlab is introduced.Then the definition of construction reliability and the basic principle of judging the quality of bridge construction are described.Finally,the application of Monte Carlo method in the reliability of T-beam construction is introduced with the example of 25 mpost-stressed concrete continuous T-beam.
