Fig. 4 3D FE numerical model of the weir structure of Ruppoldingen HPP Final Structural Safety Assessment The stability, structural and foundation stress and deformation of the weir structure for both HPPs are verified with the updated static and dynamic load cases. The maximal seismic-induced deformation of the pier is considerably smaller than the lateral 30 mm rubber sealed joint between the radial gate and the pillar. Therefore, the post-earthquake functionality of the gates is guaranteed. The radial gate of Flumenthal showed small seismic-induced yield deformations of the flap gates in downstream direction. This would in the worst case lead to a water release due to slight opening of these lateral joints. This however can be recovered within a short time. The stability analysis of the massive powerhouse structure results in safety factors higher than required. 1121
