摘要
文章以某大跨度连续刚构桥为例,采用大型有限元计算软件建立完整的有限单元模型,对该大跨度连续刚构大桥进行了承载能力极限状态计算分析,正常使用极限状态荷载组合计算分析和施工阶段应力计算分析,得出了满意的结果。对同类桥梁计算分析有借鉴作用。
This paper took a large-span continuous rigid-frame bridge as an example, establish a whole finite element model by the large-scale finite element analysis software, the spatial calculation analysis to it is made considering limit status of bearing capability,requirement construction phase, obtained satisfactory results. of normally utilized limit status and load combination Stress of the The obtained analysis results have great reference values to calculation and analysis of the similar bridges.
