摘要
为了分析风荷载对斜拉桥受力的影响,本文利用有限元软件建立斜拉桥的有限元模型,采用等效风荷载的方法得到桥梁风荷载的大小,分析了风荷载对桥梁的影响规律。为工程实践提供了相应的理论科学依据。
In order to analyze the effects of wind loads on cable-stayed bridge, firstly, the paper establishes the model of cable-stayed bridge using finite element software, then obtain bridge wind loads size by equivalent wind load method. The results show main girders have large lateral displacement under wind loads~ which will provide a theoretical science basis for the practice of engineering.
