On the other hand, depending on the application in question, the predictions of ACI are sometimes unconservative and sometimes conservative. The failure is governed by crack growth in concrete, which forms a typical cone shape having the anchor’s axis as revolution axis.
From Wikipedia, the free encyclopedia. Test results showed that pullout capacities aco the anchors were not significantly affected by the addition of steel fibers into the concrete. However, formatting rules can vary widely between applications and fields of interest or study.
This article reports on a study of the load-deflection behavior of adhesive and grouted anchors embedded in both plain and steel fiber-reinforced normal- and high-strength concretes.
