A numerical method of analysis is developed to trace the quasi-static responses of various types of reinforced concrete structures under sustained loads. Ultimate collapse of shear panels, slabs of arbitrary geometry and free-form, shell-type structures are then predicted considering local failures in steel and concrete along with deterioration of structural stiffness due to progressive cracking. A finite element tangent stiffness formulation coupled with a time step integration scheme is developed to analyze the reinforced concrete systems. Numerical results demonstrate close correspondence with available experiemental data.
