摘要
利用ANSYS软件,对一座斜拉桥建立了空间非线性的参数化模型,利用ANSYS软件的可靠性分析模块,建立了可靠性分析文件,对该桥在风荷载作用下的可靠性进行了研究,采用蒙特卡罗方法对该桥进行了可靠概率的计算,说明蒙特卡罗数值模拟与有限元程序相结合是研究结构可靠概率的一个有效的方法。
Utilizing ANSYS spatial parameterized nonlinear model of one cable-stayed bridge is established. Based upon reliability analysis module of ANSYS files for reliability analysis are generated. Further research is also made on its reliability under the actions of wind load. Monte Carlo method is used for reliable probability calculation. Practice show the combination of Monte Carlo numerical simulation and finite element analysis is one effective method for reliable probability analysis of structure.
