Behavior and Durability of Ceramic Heritage Masonry in Near Source Fault Zone

Abstract eng:
The metropolitan area of Mendoza is the largest city exposed to seismic risk in Argentina. The last significant earthquake, 1861, originated in the near faulting, destroyed the city and killed half of its population. Very few construction of that time has been maintained. Subsequent earthquakes, significantly affected adobe buildings and unreinforced masonry and few buildings of historic masonry can be located. The methodology used to carry out the objectives includes the stages: detailed survey, emergency decisions, analysis of the conservation conditions of the building, diagnostic and proposal rehabilitation. Physical and mechanical features of local masonry mortars and units indicate resistant levels under standards. In addition to this, there is chemical attack of salts from the same masonry or from the presence of capillary water, leading to a decreased capacity. The site features, quaternary geological formation, in soils disposal in alluvial fan with alternate layers of silts and clays. The conditions of conservation of masonry construction are affected by environmental conditions of use and maintenance. This paper presents the results of performance and durability of four ceramic heritage masonry buildings evaluated for enhancement, the study techniques of applied materials and environmental conditions and the criteria chosen for modeling the historical masonry are evaluated.
