- Abstract:
- Computational modelling is employed to investigate the mechanical behaviour and failure scenarios of the Marble block - Steel clamp ancient masonry system utilized on the Athens Acropolis monuments, under static loading and modal analysis. The input data for the model are acquired by laboratory testing results such as tensile strength measurements and metallography, as well as bibliographic sources from various scientific fields (i.e. materials properties, archaeometry, restoration, structural engineering and geology). The effects of corrosion to the mechanical behaviour of the clamps are examined for two types of steel (E = 50 and E= 200 GPa) and the mechanical behaviour of the clamp - marble block system is examined for three realistic scenarios: (a) a well preserved ancient clamp, embedded in cast lead metal, (b) a well preserved early 20th century restoration clamp, embedded in Portland cement mortar and (c) a heavily corroded clamp surrounded by corrosion products. The aim is to build up a methodology that will take into account different states of preservation of the original and/or the restoration materials. This methodology could evolve further and be used as input for scaling up to structural engineering modelling.
