چکیده:

Rehabilitation and strengthening of existing adobe masonry constructions have been neglected during the last decades. In Aveiro, Portugal, many adobe buildings present an important level of structural damage and, in many cases, are even near to ruin, having the majority a high vulnerability to seismic actions. To face the lack of information concerning the mechanical properties and structural behaviour of adobe elements, it was developed an experimental campaign. The composition and mechanical behaviour of adobe units and mortars were studied. Laboratory and in situ tests on full-scale adobe masonry walls were performed. Adobe walls were subjected to imposed horizontal cyclic displacements. Test results reveal the behaviour and structural fragilities of adobe elements, and will help in the assessment of existing adobe constructions, and in the strengthening strategy definition.
