| Popis: |
The models included in the current standards and guidelines (EN1992-4, ACI 318, fib Bulletin 58) to evaluate the failure loads for anchorages with supplementary reinforcement in the form of hanger reinforcement and stirrups subjected to either tension or shear forces are conservative compared with the results of corresponding experiments. In this work, a new analytical model is developed based on experimental investigations performed on anchorages, using WELDA® anchor plates from Peikko Group Corporation, with supplementary reinforcement to take up tension forces subjected to tension loads and anchorages with supplementary reinforcement to take up shear forces close to an edge loaded in shear perpendicular and towards the edge. The model for reinforcement is an adaptation of the model proposed by Schmid (2010) based on research performed at the University of Stuttgart. The mean failure loads calculated by the new model are shown to be in very good agreement with the experimentally obtained mean failure loads. The model is objective and is applicable equally well for anchorages with supplementary reinforcement under either tension or shear forces. |
