Has anyone ever used the tangent stiffness method (Santathadaporn and Chen) to develop moment-curvature relationships for a composite steel section?

I have a steel section comprised of CFRP sheets (Fy= 250 ksi, E= 20000 ksi) and a WF steel beam (Fy= 50 ksi, E= 29000 ksi). My computer program develops the moment-curvature relationship for the...
