For the elevated structure of Metropolitan Atlanta Rapid Transit Authority's (MARTA) system, bolted connections were designed to provide composite action between the precast concrete deck slab units and the main longitudinal girders. The connections were designed using the shear-friction procedure described in Section 11.15 of the 1971 ACI Building Code, Pretorqued bolts were used as "reinforcement". The paper describes tests of 16 specimens that simulated the joint between the deck and the girder of the MARTA structure. Controlled variables included use of concrete girder, steel girder, different size bolts and different times of grout between deck and girder. The specimens were subjected to repeated loads of either 2 or 5-million cycles. These tests provided a means for determining the behavior of the bolted connection under repeated loading. The test results are compared with values calculated according to the shear-friction concept. Design recommendations are presented. (Author)
