Continuity Diaphragm for Skewed Continuous Span Precast Prestressed Concrete Girder Bridges
Continuity diaphragms used on skewed bents in pre-stressed girder bridges cause difficulties in detailing and construction. The bridge parameters considered in the study described in this paper are based on results of a survey sent to other states' bridge engineers and design of experiment techniques. The parameters include girder type, bridge skew angle, girder spacing, span length, and diaphragm skew angle. The effects of continuity diaphragms on stresses and deflections from truck and lane loading on continuous skewed bridges are evaluated and results provide a fundamental understanding of the load transfer mechanism in diaphragms of skewed bridges.
