ABSTRACT

In some cases, the assessment of the safety of historic buildings may require the evaluation of their vulnerability toward the effects of persistent loading. The problem of achieving a reliable lifetime estimate of this kind of structures involves many uncertainties. Therefore a probabilistic approach seems to be needed.

The lifetime assessment of ancient structures is investigated here through a simple stochastic approach, modelling the results of laboratory creep tests on the masonry of ancient buildings.

KEYWORDS: historic masonry, long term behaviour, probabilistic approach, fragility curves
