摘要
宽跨比较大的箱梁,应力的横向分布较为复杂,以实际桥梁工程为例,采用Midas FEA程序建立实体有限元模型,根据预应力宽箱梁的受力特点,计算分析各种效应的横向应力分布,得出各种效应的横向分布规律,以供桥梁设计者参考。
The transversal stress distribution of the box beam with bigger widthspan ratio is relatively complex.Taking the actual bridge project as an example,the solid finite model is established adopting Midas FEA procedure,the transversal stress distribution is calculated and analyzed according to the forcing characteristics of prestressed wide box beam,thus the transverse distribution law of various effect is obtained,which can provide reference for bridge designers.
