An Experomental study of High-performance hybrid steel-concrete beam connections under cyclic loading

Abstract

In thid study, new moment- resisting PC beam-column joint was made up of hybrid steel concrete. It has square hollow tubular section in concrete column and connecting plat in precast U-beam. And we use the ECC. An experimental study was carried out to investigate the joint behavior subjected to reversed cyclic loading. Two Precast beam-column joint specimens were tested. The variables for interior joints were cast-in-situ concrete area and tranceverse reinforcement within the joint. Based on the test results, we observed main differences of structural behavior because of different bonding characteristics in relation to steel, concrete and ECC. This connection detail is able to induce the plastic hinge from the ECC and steel plate.
