Abstract

This chapter presents the results of a comprehensive experimental study where engineered cementitious composite (ECC) was employed to encase the steel section. As the production cost of ECC is relatively higher than that of normal concrete (NC), an efficient configuration of the beam is proposed by only encasing the flanges of the steel section using ECC while the remaining portion of the web is encased by lightweight concrete (LWC). In all, 15 simply supported beams fabricated with different material, geometric, and encasement configurations were tested under bending. Flexural resistance, failure modes, and strain analyses of the tested beams were compared with similar bare steel beam and/or NC encased steel composite beams. A significant enhancement in flexural behaviors was achieved for the proposed beams when comparing with the bare and/or NC encased steel beams. It was further noticed that the compressive ECC layers crushed after the compressive flanges were yielded and therefore successfully prevented the onset of lateral buckling.
