Abstract

This paper presents an experimental program investigating the behavior of single adhesive anchors embedded in precast concrete sandwich wall panel systems under tension loading. Variables included concrete thickness, concrete compressive strength, anchor diameter, and adhesive manufacturer. Anchors were embedded in the full thickness of the concrete member, and the effects of back-face blowout due to drilling were considered. The results showed that the concrete capacity design model with an effective embedment depth equal to the concrete layer thickness can be used to calculate the tensile capacity of adhesive anchors with full-thickness installation in thin concrete members. The average experimental-to-calculated ratio for the test program was 1.1 with a coefficient of variation of 0.2. Based on the experimental results, behavioral and design models are proposed. The proposed model results in levels of accuracy and variability that are consistent with other types of anchorage and the associated models.
