FATIGUE TESTS OF BOLTED CONNECTIONS DESIGNED BY SHEAR FRICTION
The elevated structure of the Metropolitan Atlanta Rapid Transit Authority involves bolted connections designed to provide composite action between precast concrete deck slab units and the main longitudinal girders. The connection employs pretorqued, high-strength bolts not only to simplify assembly but also to produce a clamping force to maintain compression in the grout layer between girder and deck slab and to eliminate stress changes and minimize fatigue effects. This publication describes 16 test specimens that simulated the joint, producing data concerning the integrity of such connections under repeated loads from 2 to 5 million cycles.
