Secondary bending moment in the design of beam with trapezoid web profile

Secondary bending moment, Myf is particularly occurs to corrugated web or beam with trapezoid web profile (TWP) subjected to in-plane shear force which causing flange of TWP beams to bend in lateral direction. Therefore, flange will experience double axial bending (bending in major and minor axis)....
