Abstract

Abstract

In order to ensure a safe design of a new building and obtain optimum design,an experimental program consisting of the tests of three full-scale connections with different connections details under cyclic loading,which were alternative design schemes for a twenty-eight-story prototype office building,was conducted to evaluate the seismic behavior of concrete filled rectangular tube column-to-H beam connections.Performance of test specimens was evaluated in terms of failure mode,hysteresis curve,ductility and energy dissipation capacity,etc.Test results showed that all specimens performed in a ductile manner with plastic hinges formed in the beam end near the column face,and exhibited a strong column-weak beam failure mechanism.The hysteresis curves of all connections were full and showed good energy dissipation.There were no obvious discrepancies in load bearing capacity and energy dissipation among three connections when story drift was not beyond 2%.The stiffness degradation trends were similar to each other.
