为了利用计算机技术对混凝土湿热耦合传输及变形进行数值模拟分析,并在实际工程结构变形预测中有效应用,根据提出的基于Visual Basic调用Matlab及ANSYS的软件开发策略,通过混合编程开发了混凝土湿热耦合数值模拟计算程序软件(CTMSoft)。利用CTMSoft对实际工程结构中混凝土的湿热传输及变形进行了数值模拟,模拟分析结果与现场实际试验及结构监测结果一致,证实该方法和程序软件是正确有效的。
The coupling temperature and moisture simulation system (CTMSoft in short) is developed by mixed programming according to the policy of calling Matlab and ANSYS based on Visual Basic for numerical simulating the heat-moisture transfer in concrete and induced deformation by computer technology in order to predict the deformation of engineering structure efficiently. The heat-moisture transfer and deformation of the concrete in practical structure are numerical simulated by CTMSoft. The results of numerical simulation, field test and fiber Bragg grating (FBG) monitoring are comparatively analyzed. The coherence between them reveals that the method and software developed are effective and accurate.
