Abstract

The strengthening technique of historical buildings is often based on steel ties. In precious facades, external anchor plates cannot be adopted so that ties can be restrained to the masonry wall by using grouting material. The tie efficiency depends on the properties of the injection mortar as well as on the masonry mechanical properties. In the present work preliminary results of pull-out tests on threaded steel bars anchored in masonry walls with different types of grouting materials are presented. 1 Introduction The restoration of historical buildings often requires structural strengthening. Frequently the strengthening technique is based on the insertion of steel ties which link the masonry walls or part of them together.' This kind of intervention is well accepted because the
