摘要
石板坡大桥主跨由钢箱梁与预应力混凝土箱梁组成。针对该桥钢箱梁桥面板局部受力复杂的情况,运用ANSYS软件建立了钢箱梁结构分析的空间有限元模型,分析了钢箱梁在车载作用下局部应力的分布特点。
The main span of the Shibanpo bridge is made up of steel-box girder and prestressed concrete-box girder. In the light of the complexity of local stress conditions at deck of the steel-box girder, the ANSYS software is used to establish the finite element space model of steel-box girder, and the characteristics of local stress distribution at deck of steel-box girder are analyzed.
