Analysis of comparison internal forces of girder consists of shear forces and bending moment on bridge structure at port in Subang Regency West Java.

Bridge construction design on this design used a prestressed PCI concrete I-Girder. The span of bridge was 40 m which is consist of 3 spans with total length for 120 m. The calculation of the analysis for the structure depends on the structural type. For this design, the bridge was assumed to be indeterminate static which the bridge reactions are more than 3. The internal forces of I-Girder consist of shear forces and bending moment which can be get by simulate the bridges loading that related to the bridge structure. The software for designing the bridge structures and obtained the internal forces value are using SAP 2000 software and manual calculation method. The internal forces data was obtained by calculating the girder structure using manual calculation and analyze using SAP2000 software and be compared by the values. The internal forces is taken at 20 m, 30 m, and 40 m span of girder to be compared the difference value of manual calculation and software analysis using regression line. [ABSTRACT FROM AUTHOR]
