Název v původním jazyce

Updating finite element model of façade scaffolds anchor considering experimental data

Popis výsledku v původním jazyce

Considering the stability of the façade scaffolds, the anchoring is one of the most important phenomenon. The anchors secure scaffolding against the overturning and prevent transfer of the horizontal forces from the scaffold into the façade. There are many different types of the anchors in the construction field, but the same principle has been used to join these anchors to the thermal insulated façade. A new type of façade scaffold anchor has been developed and presented in this paper. The new developed anchor overcomes the problems associated with the existing anchoring. Main problems associated with the existing anchors are: damage of the façade thermal insulation layers, provide insufficient support and decrease in the stability of the scaffold construction. Experimentation has been carried out on the developed anchor and it has been observed that the experimental results (force–displacement curve) do not match with the finite element predictions. Subsequently, the finite element model (FEM) of the developed anchor has been updated in the light of experimental results. The finite element model of the anchor is corrected using the parameter-based finite element model updating method. The results have shown that there is a good correlation between the updated finite element model and the experimental data. The accuracy of updated finite element model is demonstrated by plotting the predictions made by finite element model with experimental results. The overlay of finite element model predictions and experimental data has shown the success of the updating procedure and thus it can be concluded that updated finite element model of the anchor represents the reality with confidence.
