Abstract:Four full-scale beam column slab assemblies were tested under reversed cyclic loads. The test program included two interior and two exterior joint specimens. The first two specimens, one interior and one exterior, were identical to beam column joints in the second story of the full-scale seven story structure tested in Japan. I n the remaining two specimens the longitudinal reinforcement in the beams and the columns was increased to provide a variation in beam-to-slab strength. Results are presented to give an overview of the experimental program. The behavior of the four specimens under reversed cyclic loads was excellent up to story drift levels estimated to correspond to the maximum deflection level imposed on the seven story structure. The influence of the slab on the strength of the floor system under imposed deformations was significantly greater than would be anticipated using the ACI effective slab width as a flange for T-beam analysis.
