Recently, the SCP(Steel Confined Prestressed concrete) composite girders are developed to improve the characteristic such as displacement, vibration, and heavy dead load due to influence of self weight, and inefficiency of steel section of exiting girder-type railroad bridges. It is needed to verify the economical effciency of newly developed SCP composite girder bridge compared with the conventional girder-type bridges. In this paper, LCC analysis for alternative railroad bridges Is performed and its technique based on level of risk(probability of failure) is suggested. From the results, it may be stated that SCP composite girder bridge is more economical than a conventional one.
