Abstract—This paper reports on the development of a minimum cost design model and its application for obtaining economic designs for reinforced High Strength Concrete (HSC) T-sections in bending under ultimate limit state conditions. Cost objective functions, behavior constraints including material nonlinearities of steel and HSC, conditions on strain compatibility in steel and concrete as well as geometric design constraints are derived and implemented within the Generalized Reduced Gradient optimization algorithm. Particular attention is paid to problem formulation, solution behavior and economic considerations.
