The Effect of Diaphragms in Prestressed Concrete Girder and Slab Bridges
Four scale microconcrete model bridges were tested. Experimental variables included span, skew angle, stiffness, location and number of diaphragms. Service load level behavior was studied under static, cyclic and impact loads with successive removal of diaphragms. Behavior at overload and ultimate load conditions was documented from ultimate static and impact load tests. Characteristics studied were load distribution under static service loads and overloads, ultimate load capacities and failure modes of girders, cracking and ultimate load capacities of slabs, dynamic amplification, bridge damping, fundamental modes of vibration and natural frequencies, response to lateral impacts, and stresses in diaphragms. A computer program was verified with experimental results and used to beneralize findings. (Modified author abstract)
