What this tool does

Predicts the shear forceā€“shear distortion (V-Ī³) backbone of the column web panel zone in steel moment-resisting frames, including the effect of doubler plates, using the panel zone model of Skiadopoulos et al. (2021). You can save each plot as PNG or SVG and the curve data as CSV.
