3.5.11: Optimize Reinforcement π·
The βOptimize Reinforcementβ-component calculates reinforcement quantities for arbitrary shells. The algorithm is based on the sandwich model approach of Marti (see [6] or [4]). Each load-case is considered separately and the maximum reinforcement of all load-cases is chosen.
The input-plugs of the βOptimize Reinforcementβ-component are similar to those of the βOptimize Cross Sectionβ-component:
Under the submenu βSettingsβ reside two plugs which let you specify the partial safety factors for concrete (βgammaMcβ) and steel (βgammaMsβ). The former exists for future use, since currently concrete is assumed to be infinitely strong in compression. The latter is set to 1.15 which constitutes the standard value according to Eurocode 2 (see [3]). The output of βOptimize Reinforcementβ comprises these plugs:
The βShellViewβ-component lets one display the thickness of the reinforcement layers and the stresses there (see fig. 3.5.11.1). The input-plug βLayerIndβ sets the index of the layer to be displayed. The concrete cross section has index zero, index one corresponds to the top-, index four to the bottom-most reinforcement layer. The Z-direction of the local coordinate system points to the top of the cross section. The entry βLocal layer axesβ under βDisplay Scalesβ in the component βModelViewβ lets one enable, disable and scale the arrows of the local coordinate system.
