摘要: Masonry is the oldest building material that survived until today, being used all over world, and present in most impressive historical structures. There a considerable amount of existing masonry buildings using granite as unit. Conservation, rehabilitation, strengthening built heritage protection human lives are clear demands modern societies evaluation stability conditions damaged ancient constructions involves frequently usage more advanced numerical tools than linear elastic analysis, where knowledge mechanical properties stone required. This work aims at obtaining compressive improving understanding fracture process granites. Based on an enlarged experimental program uniaxial tests different lithotypes, it was possible to obtain complete stress-strain diagrams through appropriate circumferential displacement control, from which were derived. A comprehensive discussion parameters influencing behavior such planar anisotropy, weathering state, physical also provided.
