EXPERIMENTAL INVESTIGATION OF FLANGE PLATECONNECTIONS BETWEEN CONCRETE-FILLED TUBE COLUMN ANDSTEEL BEAM

摘要

This study investigates the cyclic behavior of flange plate connections between steel beam and rectangularCFT column, in which the flange plates were penetrated through the CFT column. The steel tube of flangeplate connections tore at the tips of the weld joining the flange plate to the steel tube. Specimens withadequate shear capacity in the panel zone formed the plastic hinge in the beam, while specimens withweak panel zone demonstrated the shear cracking in the concrete core, and fracturing of the steel tube.The specimen with connection of whole beam through the column possessed stable hysteresis curve.
