大跨度悬索桥非线性静动力分析与软件开发

Analytic Theories and Software Development of Spatial Non-linearity Static and Dynamic of Long-span Suspension Bridge

大跨度悬索桥是典型的柔性结构体系 ,其受力特性表现为强烈的几何非线性。介绍了适用于大跨度悬索桥空间非线性静动力有限元计算的程序的模型、原理及软件设计 ,并对一座大跨度悬索桥作了结构静动力计算。

Long\|span suspension bridge is typically the flexible structural system whose mechanical properties strongly manifest themselves as geometric non\|linearity.Models,principle and software design of programs suitable for finite element calculation for spatial non\|linearity static and dynamic of long\|span suspension bridge are presented.A case calculation for structural static and dynamic of a long\|span suspension bridge is made.
