Consolidation and Strengthening of Historical Masonry by Means of Mineral Grouts: Modeling Structural Behavior of Grouted Three-Leaf Masonry

Abstract

Abstract Development of mineral grouts for consolidation and strengthening of historical masonry was discussed in Ref. [1]. The properties of the injection grout must counteract the elements that initiate the failure mechanism of multiple leaf historical masonry and lead to its collapse. This paper presents a macro-approach to model the structural behavior of three-leaf masonry. A global approach is used, based on the properties and the behavior of the external leafs, in combination with the properties and behavior of the central core of the three-leaf wall. Evaluation of the models is made by comparison with experimental data.
