STUDY ON OPTIMIZATION FOR SYSTEM RELIABILITY OF SOIL-SUPPORTED STRUCTURE

摘要: The structure is composed of a superstructure and foundation. foundation are designed separately in the present design method, but it an ideal that optimum carried out as one system. paper describes procedure optimization for system reliability spoil-supported structure. Each alternative decided by minimizing expected total cost whole. plate girder bridge constructed on poor ground examined case study. safety factors main girders from view point reliability.
