Abstract
Design of reinforced concrete structures is governed by the nonlinear behavior of concrete and by its
dierent strengths in tension and compression. The purpose of this article is to present a computational
procedure for optimal conceptual design of reinforced concrete structures, based on topology optimization
with elasto-plastic material modeling. Concrete and steel are both considered as elasto-plastic materials,
including the appropriate yield criteria and post-yielding response. The same approach can be applied
also for topology optimization of other material compositions where nonlinear response must be consid-
ered. Optimized distribution of material is achieved by introducing interpolation rules for both elastic
and plastic material properties. Several numerical examples illustrate the capability and potential of the
proposed procedure.
