Abstract

This paper describes and analyses the performance of two structural strengthening solutions for rubble stone masonry walls. The strengthening solutions are characterised by: sprayed micro-concrete steel reinforced layers on both lateral faces of the walls, with transversal steel ties through the thickness of the specimens, not in contact with the base of the loading systems; sprayed micro-concrete steel reinforced layers on lateral faces of the specimens, without transversal steel ties but in contact with the base of the loading systems. For the first solution three specimens were tested under axial compression load and three under compression-shear load, and for the second solution three specimens were tested under axial compression load. The results are compared with unstrengthened (reference) specimens. Strengthening solutions of this nature have been used in the rehabilitation of old masonry walls in Portugal, particularly in Lisbon downtown, and in the rehabilitation of some Azores buildings after the 1998 earthquake.
