Experimental study of encased composite corrugated steel webs under shear loading

Abstract

This paper focuses on enhancing the shear strength of steel I-girder using different types of corrugation filled by concrete. This study used three types of corrugation shape (triangular, trapezoidal, and rectangular). Corrugation shapes had the same depth (60 mm). All specimens used in the study had equal weight, which is approximately (38) kilograms per specimen. The specimens were categorized into two groups, the first group without encasing by concrete while the second group contains self-compacted concrete to encase the corrugated steel web for two faces of I-girder. The experimental work included measuring the ultimate load capacities and load -deflection curves . The experimental results showed that the concrete filled corrugated web girders have high shear strength compared to the specimens that don't have concrete encasing. Also, the shape of the corrugation was found to have an impact on the shear strength of the steel girders encased with concrete.
