Probabilistic Analysis of Anchor (Dowel) Pull-Out Capacity in Aerated Concrete

Abstract

Aerated concrete structures are widely used in construction as load-bearing or filler structures. The article describes the probabilistic approach to estimation of anchor (dowel) pull-out capacity. The article also presents the experimental studies of control samples from aerated concrete and diagrams “stress – strain”. The maximum permissible load values are obtained for the given batch of aerated concrete blocks based on the requirements of ensuring the specified reliability (probability of no-failure). Permissible load on the anchor (dowel) will also depend on the number of anchors in case of set of anchors as a conditional sequential mechanical system in terms of reliability theory. The design equations is given the reliability analysis of anchor (dowel) on pull-out force with limited statistical data and small number of control samples for using probabilistic and statistical approaches.
