ECCS EC3 Steel Member Calculator provides a database of hot-rolled I-section profiles; cold-formed and hot-finished tubular profiles, as well as a database of mechanical fasters, and calculates the resistance of hot-rolled I-section profiles and cold-formed and hot-finished tubular steel columns, beams (subject to major axis bending) and beam-columns (subject to axial force and major-axis bending) according to EC3-1-1.
