WORKABILITY TEST OF STEEL - CONCRETE COMPOSITE BEAM USING HAT SHAPED STEEL SECTION

Abstract

Steel-Concrete composite beam (SC beam) using hat shaped steel section has been developed by authors. This beam makes it possible to omit stirrups, reinforcements for web openings, and concrete form supports. The structural performance of this beam after concrete hardened is shown by other report. In this study, we show the validity of the one side shear connection using drill screw when the hat-shaped steel section is formed from a pair of Z shaped steel section. And also, this paper reports the result of experimental and analytical examination of the behavior of this hat shaped steel beam at the time of concrete casting.
