Further Considerations for Nonlinear Finite-Element Analysis

Abstract

The results from a nonlinear finite-element analysis (NLFEA) of a reinforced concrete (RC) slab bridge are presented and discussed. The analytical results are compared with those obtained in 1993 by Huria, Lee and Aktan and their differences are discussed. The analytical results are also compared in general to experimental results on a similar structure, as presented by Aktan, Zwick, Miller and Sharooz in 1992. The analyses predicted approximately the same ultimate failure load as that experienced by the bridge, but the failure mechanisms differed. All of the differences mentioned are used as the basis for additional recommendations to practicing engineers for conducting NLFEA of RC structures.
