- Abstract
The experimental study was carried out to assess the suitability of three proprietary post-installed anchors from Simpson Inc. for use under high strain-rate loading, such as blast loadings, in both tension and in shear. The anchors investigated included two torque-controlled expansion anchors (Strong Bolt® 2, Wedge-All®) and a screw anchor (Titen HD®) . While three different diameters (6.4 mm, 9.5 mm and 12.7 mm) of the Strong Bolt® 2 and Titen HD® anchors were investigated, only two diameters (9.5 mm and 12.7 mm) of Wedge-All® anchors were investigated. The anchor capacities under static loading conditions with average strain rate of 3.0 × 10-4/s were compared with those for impact-loads with average strain rate of 1/s to define a Dynamic Increase Factor (DIF). The failure modes under both conditions were also assessed to ascertain the change as the loading rate increased.
