ABSTRACT

In order to study the hysteretic performance of connections to gangue, tests of steel beams to gangue concrete-filled steel tube column (CFST) with ring stiffeners under low reversed cyclic loading were carried out including interior and exterior connections. The gangue is industrial waste dug out from under ground with coal. The curves of load and beam end displacement, strength degeneration, rigidity degeneration were drawn. On the basis of the above, the hysteretic behavior, energy dissipation, rigidity degeneration, strength degeneration and ductility of the joints were studied. It’s shown that the joints of gangue CFST are featured with excellent quake-resistance and excellent hysteretic performance, energy dissipation and ductility. It will be referred to structure design and project application. This lays a good foundation in the application of gangue concrete-filled steel tubular structure.
