Uncertainty quantification of extrapolation techniques for bonded anchors
Original language description
The multi-decade deformation prediction of bonded anchors under sustained load is paramount to the safe and economical design of civil structures, especially for adhesive anchors. Yet, there is considerable lack of guidelines on how to actually predict the life-time performance of such systems given various installation and in-service conditions, the aging visco-elastic nature of both involved materials – concrete and polymer-based mortar – and typically short observation durations of weeks only. In this contribution the authors critically review the current practice of product qualification by means of 1000 hour creep tests on entire anchor systems, extrapolated to 50 years and compared to a deterministic limit. Based on available data sets for two typical products on the market the current practice as specified in most normative documents and recommendations is investigated, both from a scientific and practical point of view. As a result, uncertainties owing to different sources are elaborated, the suitability of the creep prediction model in combination with various extrapolation techniques is evaluated, and safety factors based on those are discussed.assessment of concrete fastening systems.
