Abstract
During the last few years a considerable research on the behaviour of masonry structures has been experienced mainly on the experimental testing of bricks, mortar and brickwork. In this paper attention has been focused on some problems arising from a great deal of tests carried out on bricks removed from ancient buildings. The testing experienced on both ancient and new bricks has pointed out either some analogies and differences in the mechanical behaviour of such samples due mostly to the different manufacturing techniques used. The results obtained showed that the most appropriate mechanical characteristics and the testing process to be used shouldn’t be the classical ones. lt urges then the necessity of individualizing new and more appropriate parameters in order to represent some aspects of inelasticity.
