Seismic Performance of Moment End-Plate Connections to CFT Column under Cyclic Loading

Sheet, Ikhlas S. / Gunasekaran, Umarani

An experimental program under cyclic load is performed on two half-scale interior moment end-plate connections to concrete filled tubular (CFT) columns. Flat and curved stiffened extended end-plates were welded to the steel beams in the shop, and bolted on the site to the square and circular CFT column tubes respectively, using steel rods passing through the column. The experimental results demonstrated that both circular and rectangular end-plate connections showed similar performance in a ductile manner and the stiffener elements were effective to form the plastic hinges away from the welding zone, also the proposed curved end-plate connection with rods passing through the column in “X” shape was effective. The test specimens showed a plastic rotations capacity of 0.054 radian.
