Study on the Displacement Characteristic of Uplift Anchor under Cyclic Loading

Abstract:

This paper presents the results of the cyclic loading tests for 30 uplift anchors. The relationship between the loads and displacements for each anchor under cyclic loading is studied and the results show that the behavior of the anchor is largely influenced by its length. It is common for the Q-S curves of different anchors to vary quite widely. The displacements under different load levels decrease with increasing anchor length but the decreasing rate has a number of variations. It is also found that the final displacements of the anchors are dominated by plastic displacements which positively correlated with the peak loads. In addition, the effective length of the anchor is related to the load acted on it.
