Experimental study of post-installed anchor embedded in concrete under simulated seismic and wind loads

Abstract

In this study, experimental protocol to simulate wind-induced vibration of post-installed anchor embedded in concrete was developed. The proposed loading protocol was based on the ratio of deformation due to seismic load and dynamic wind load of anchors in the connection between the sign structure and the concrete building. Then, based on ACI 355.2 and the developed protocol, numerous experimental tests were conducted to evaluate the performance of anchor under simulated seismic and wind loads. In simulated seismic test, crack width of concrete did not affect the performance of anchor. Their maximum force as well as residual capacity showed practically the same value. Moreover, anchor used in this experiment satisfied the condition to be rated as full capacity for seismic performance. In simulated wind test, the crack width did not cause any difference in performance of the anchor in tension test. Though, in simulated wind shear test, there was a major difference for the anchor residual capacity. Additionally, the performance of anchor in simulated wind test did not satisfy the criteria to be rated as full capacity.
