Abstract
Last few decades, corrugated web steel girders have the foremost widespread and used steel constructions due to their lightweight and high load carrying capacity compared with the stiffened flat web. This study aims to comprise an experimental work by testing ten specimens to improve the girders shear resistance. One reference specimen with a flat web in addition to nine models that are categorised to three groups in which each group differs in the corrugation shape. Rectangular, trapezoidal and triangular corrugation shapes of different heights (20, 40, and 60 mm) were utilised. All specimens used in the study have equal weight, which is approximately 30 kilograms per specimen. The experimental work included measuring the ultimate load capacities and load-deflection curves. Results showed that different failure modes were observed for those beams. It was also found that the beam with trapezoidal corrugation web has an increase in its strength by nearly 28% compared with the reference beam.
