✦ Synopsis

This paper aims to investigate the seismic behavior of steel beam to reinforced concrete column connections with or without the floor slab, acting as a proof test for a three-story-three-bay reinforced concrete column and steel beam (RCS) in-plane frame tested at the National Center for Research on Earthquake Engineering (NCREE), Taiwan, by the Taiwan-USA international research cooperation group. In total, six cruciform RCS joint sub-assemblages were constructed and tested. Parameters considered included composite effects of the slab and beam, the tie configuration in the panel zone, effects of the cross-beam, and the loading protocol. Force-deformation behavior was also simulated by a nonlinear analysis program, DRAIN-2DX, with consideration of composite effects of the beam and slab as well as shear distortion in the panel zone. Test results showed that all specimens performed in a ductile manner with plastic hinges formed in the beam ends near the column face. It was found that the ultimate strength of the composite beam was increased by 27% on average, compared with that of the steel beam without the slab.
