Shape factor for i section
WebbFör 1 dag sedan · For a circular cross-section of radius, r, A = p r 2 , and I = ( p r 4 /4) so that the shape factor for bending is f B = 1. The twisting (or torsional) response of a section will depend upon a torsional shape factor, f T = 2 p K/A 2. Here K is the "torsional moment of area" about an axis normal to the section.
