Abstract

Abstract: The paper is focused on presenting the thermal and mechanical response of sinusoidal corrugated web beams subjected to high temperatures. Two tests were performed to monitor the behavior of isolated elements and composite slabs designed with corrugated web beams. Different aspect ratio beams exposed to standard fire temperatures and one beam subjected also to mechanical load were tested in the first experiment. The second study was conducted on a real-scale building compartment designed using corrugated web beams–concrete slab composite floor. The results obtained from experimental works reveal the real temperature distribution in the steel profile and the fire performance of sinusoidal corrugated web beams. Highlights: Two fire tests reflect the thermal and structural response of corrugated web beams. Uneven temperatures develop along the web height. The failure mechanism is expected to appear in the web. Enhancement of beam resistance is achieved by composite floor action.
