| Abstract: | The interchange at Siping Railway Junction of Harbin-Dalian Passenger Dedicated Railway is designed as the prestressed concrete(PC) continuous box girders of constant depth and variable width with main spans each 48 m in length.In this paper,the universal finite element analysis software ANSYS is used to establish a spatial solid finite element model for the irregular shape PC box girders and the structural behavior of the girders is comparatively studied in accordance with the calculation results of the plane beam element. |
