Structural behaviour characterization of existing adobe constructions in Aveiro

Abstract

Adobe was a widely used construction material in Aveiro, Portugal, till the middle of the 20th century. Nowadays, adobe can still be found in varied types of constructions, many of which are of cultural, historical, and also architectural recognized value. The existing 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 structures, it was developed an experimental campaign. The composition and mechanical behaviour of adobe units and mortars were studied. Laboratory and in situ cyclic tests on full-scale adobe masonry walls were performed. Test results reveal the behaviour and structural fragilities of adobe elements.
