This study intends to relate the point-wise limit state design method to the ultimate behavior of reinforced-concrete shells as a unified approach. A vector algorithm developed on a Cray Y-MP supercomputer is suitable to implement an inelastic finite element program. A bending inelastic finite element model, which incorporates the rotating cracking model by layering the subdivided elements, is developed. Effects of large-deformation, tension-stiffening, and dowel action are ignored, and the bond between the concrete and steel and among the subdivided layers is assumed to be perfect. The biaxial behavior of uncracked concrete and the uniaxial behavior of a cracked element are assumed to be linear elastic in compression and in tension. Based on this analysis, the current design method provides adequate strength against an ultimate failure.
