| Abstract: |
This paper deals with some basic features of optimized reinforced concrete structures. For orthogonal mesh reinforced panels with given boundary conditions and given outer geometry, the theoretical criterion for a material efficient (optimized) structural layout is established. The criterion is based on a lower bound plasticity design approach. Subsequently, by using the principle of minimum complementary elastic energy, it is shown that for optimized panels, there is a close relationship between the stress distribution in the fully cracked elastic state and the stress distribution used in the ultimate limit state. It is discussed how this finding may be used for serviceability analysis of optimized structures. |
