Long and short steel anchorages are often used in the strengthening of rubble stone (heterogeneous) masonry walls. At design stage it is important to predict mechanical behaviour and durability of such anchorages, used for rehabilitation of masonry buildings.
This paper presents the results of a study related to an anchoring system, developed by the Portuguese company ZIRCOM Engenharia S.A., carried out on different masonry specimens built up for this purpose. The results include the analysis of cover deviation and mechanical behaviour (observed in pull-out tests) of long and short anchorages embedded in masonry.
This study has been developed at Faculdade de CiÃªncias e Tecnologia of Universidade NOVA de Lisboa (FCT-UNL), since January 2012, on request of ZIRCOM Engenharia S.A., and with the participation of A2P Consult, Ltd, a Portuguese design and consulting company.
