摘　　要：介绍了结合当前有限元和计算机的最新发展研制成的几种大型有限元结构分析程序包 ,对新一代面向微型计算机的大型结构有限元分析程序 COSMOS/ M作了较为详尽的阐述 ,同时给出了该程序在桥梁工程中的具体应用实例。结果表明在对桥梁工程的设计。Several program packages,which have been developed based on the latest development of the finite element(FE) technology and the computer,are introduced for large structure finite element analysis(FEA). Meanwhile,the recently-published large structure FEA program COSMOS/M facing personal computers is dissected,and examples are given to show the application of the program in the bridge construction. It is found that this program is a useful tool of theoretical analysis in the bridge engineering design, construction and detection.
