The purpose of this study was to investigate the design comparison of totally prefabricated bridge substructure system.\r\nPrefabricated bridge substructure systems are a relatively new and versatile alternative in substructure design that can offer\r\nnumerous benefits. The system can reduce the work load at a construction site and can result in shorter construction periods. The\r\nprefabricated bridge substructures are designed by the methods of Korea Highway Bridge Code (KHBD) and load and resistance\r\nfactor design (AASHTO-LRFD). For the design, the KHBD with DB-24 and DL-24 live loads is used. This study evaluates the\r\ndesign method of KHBD (2005) and AASHTO-LRFD (2007) for totally prefabricated bridge substructure systems. The computer\r\nprogram, reinforced concrete analysis in higher evaluation system technology was used for the analysis of reinforced concrete\r\nstructures. A bonded tendon element is used based on the finite element method, and can represent the interaction between the\r\ntendon and concrete of a prestressed concrete member. A joint element is used in order to predict the inelastic behaviors of\r\nsegmental joints. This study documents the design comparison of totally prefabricated bridge substructure and presents conclusions\r\nand design recommendations based on the analytical findings.
