Abstract

Exposed composite beams composed of H-beams and concrete slabs are generally used in building structures because of their excellent economics and flexural strength. However, deep beams used under large load often make difficulties in construction. In this study, an exposed composite beam with high strength steel (SM460) used in the bottom flange of built-up H-shaped beam, so-called S-Beam, was proposed in order to reduce beam depth. And its positive and negative flexural strengths were experimentally evaluated. The test results showed that S-Beam has excellent flexural strength and ductility.
