Topology Optimization for Conceptual Design of Reinforced Concrete Structures

Design of reinforced concrete structures is governed by the nonlinear behavior of concrete and by its different 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. 2. Keywords: Topology design, Plasticity, Reinforced concrete. Structural optimization techniques are now becoming an integral part of the design process and are widely applied, for example, in the automotive and aerospace industries. So far, optimal design had less impact on traditional structural engineering as practiced in the construction industry. One reason migh
