Finite Element Procedures Applicable to Nonlinear Analysis of Reinforced Concrete Shell Structures
The purpose of this report was to adapt earlier work in nonlinear shell-element methodology to the specific kinds of problems encountered in the analysis of critically-loaded reinforced concrete shell structures. The Continuum-Based nonlinear shell-element formulation for this shells was extended to thicker, layer-model types of shell structures. A resultant-type form of the basic equations was developed that is both appropriate for the treatment of thick, layered shells and leads to an efficient finite-element implementation as well. By eliminating most of the work associated with thickness integration, this approach should be effective when numerous layers and/or thickness integration points are required, as in the case of inelastically responding reinforced concrete. Pointwise constitutive relations for accurate through-thickness stress calculations are still employed though these are ultimately presented in the element computational routines in the form of resultants.
