文摘

A computational nonlinear reinforced concrete cross section analysis is developed. The concrete constitutive law is used in full nonlinear form given in Eurocode 2. The steel law is modelled by a nonlinear smooth function of Abbott and Richard. The strains are monitored in the cross section and rotation capacity is checked. The strategy is illustrated by the analysis of rectangular and T‐section shapes.
