Abstract Details

This study examines a variation on the prequalified double tee seismic moment connection as a candidate for use in seismic special moment frames using hollow columns. T-stubs are attached to the column by very long bolts passing clear through the hollow center. The column is then filled with grout in the connection region only. The grout surrounds the long bolt shanks inside and provides resistance to local failures. Fourteen connections were designed according to the double tee connection design procedure, for beams from 24 to 33 inches deep and columns from 14 to 22 inches wide. The connections were modeled with a monotonic displacement in Abaqus to find the moment-rotation response. All of the connections maintained adequate strength at the level of rotation required for special moment frames. Seven of the connections exhibited adequate initial stiffness to be considered fully restrained at some service moment. A cyclic analysis similar to the one to be used for prequalification testing was performed for one design. The results showed enough similarity to the monotonic analysis that cyclic analyses were considered unnecessary for preliminary evaluation; the monotonic analyses were considered good approximations of the connections’ behavior under cyclic loading.
