| Summary: | 碩士 === 國立交通大學 === 土木工程系所 === 94 === In this thesis , the stresses in connected slab , which is occurred by the differential shrinkage and creep, was investigated between new constructed and old bridge. A finite element model is established by Diana, a commercial finite element program, to explore the effect of stress in the connection slab for different environment and time after new bridge was built .The results of FE-analysis show that the shear stress is maximum at two end of the joint .Delaying the time to joint the new and old bridge and joint it at higher humidity and lower temperature will reduce the stress occur in the slab , too.
