Modelling of Bond Behavior of Injected Anchors in Masonry Elements
Key Engineering Materials(2019)
Abstract
The paper focuses attention on the performance of injected anchors embedded in masonry elements. The bond behaviour is investigated by means of a three-dimensional Finite Element model aimed to assess the global strength capacity of the injected anchors and to investigate the stresses distribution in the masonry element when some meaningful parameters change. Along the anchor-grout and grout-masonry interfaces, nonlinear bond laws have been assumed. Such laws have been assessed by comparing the FE model outcomes with the experimental results of pull-out tests carried out on ribbed steel bars embedded by means of lime-based grout in prisms made of tuff stones
