| Abstract: |
This scientific paper describes a bionic optimization of flat slabs. Emphasis is placed on the load bearing capacity, but sustainability and efficiency aspects are also considered. Previous investigations show that slabs enhanced by nature can lead to considerable material saving without loss of bearing capacity. This paper presents the results of extensive test work to optimize the punching shear resistance of flat slabs inspired by natural systems. In this case the reinforcement is positioned stress-oriented, so that a spider web-like reinforcement arrangement is created. The results of the numerical simulations show that in comparison to orthogonally reinforced slabs an increased load capacity with a smaller reinforcement ratio can be achieved. |
