Bending-Induced Cross-Sectional Deformation of Cold-Formed Steel Channel-Section Beams

Figure 7

Comparison of moment-deflection curves obtained from the nonlinear finite element analysis and the present analytical model for two channel-section beams of length l = 3000 mm (Section 1: h = 100 mm, b = 50 mm, c = 20 mm, and t = 1.0 mm; Section 2: h = 300 mm, b = 90 mm, c = 30 mm, and t = 2.0 mm).
