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 loading protocol proposed was based on the ratio of deformation due to seismic load and dynamic wind load of anchors connecting sign structure to the side of the building. Then, based on ACI 355.2 and this 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 in simulated did not affect the performance of anchor. Their maximum force as well as residual capacity show 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 different for the anchor residual capacity. Additionally, the performance of anchor in simulated wind test does not satisfy the criteria to be rated as full capacity.
