ABSTRACT
Abstract Pseudo-dynamic and cyclic tests on a full-scale model of part of the cloisters of the Sao Vicente de Fora Monastery, in Lisbon, are reported. After a first set of pseudodynamic and quasi-static cyclic tests performed on the original model, where local damages were observed, the model was retrofitted with four internal continuous bond anchors. A final campaign of quasi-static cyclic tests was carried out on the retrofitted model in order to investigate the effects of this retrofitting technique. The tests were carried out at the ELSA laboratory, JRC, and aimed at the characterization of the nonlinear behaviour of limestone-block structures under earthquake loading. Moreover, the assessment of the effectiveness of the retrofitting system was also a major objective of the test campaign. Local and overall stability of the stone-blocks, including columns and arches were assessed for large displacement amplitudes. Comparisons between the test results before and after retrofitting allowed the applicability of these retrofitting solutions and techniques for monumental structures to be investigated.
