摘要
对目前应用最为广泛的结构数值分析方法——有限元法进行了探讨,并使用空间有限元分析软件"Midas Civil"对某座预应力混凝土斜拉桥在合龙后做完二期铺装和成桥后经历十年收缩徐变的应力进行有限元数值分析。结果表明,有限元法能够对不同阶段斜拉桥的应力进行准确和有效的分析,从而为同类桥梁提供借鉴。
The finite dement method （FEM） is a structural numerical analysis method that is widely used. This paper discusses this method, and uses space finite element analysis software ＂Midas Civil＂ to ana- lyze the stress distribution of a pre-stressed concrete cable-stayed bridge whose deck pavement was com- pleted after closure and has experienced ten years of concrete shrinkage and creep.The results show that the FEM can accurately and effectively analyze the stress distribution of the cable-stayed bridge at differ- ent stages, then the FEM could provide references to other similar bridges.
