  • RELIABILITY OF CODE-PROPOSED MODELS FOR ASSESSMENT OF MASONRY ELASTIC MODULI

    SUMMARY – In this paper the results of an experimental investigation aimed to the assessment of Young moduli, rigidity moduli and other mechanical properties for different types of masonry are shown.The mechanical characteristics predicted by models proposed by some technical codes were compared against experimental data.This study was motivated by the suggestion of the Masonry Standards Joint Committee’s (MSJC) code that, while proposing the use of such models, acknowledges the lack of testing in support of their validation. The experimental investigation has included compressive tests on components (blocks and mortar), diagonal compressive tests and ordinary compressive tests (orthogonally to beds joints) on portions of masonry. The details of the experimental campaign and the prediction capacity of the above models, for the types of masonry investigated, are presented.

  • Shear performance of clay tile masonry walls: comparison between experimental and numerical response

    In the present paper the results of an experimental study for the mechanic characterization of clay tile masonry walls under shear forces are discussed. Further in the paper the reliability of the models for the prediction of the mechanic characteristics under shear forces proposed by some codes is verified. Diagonal tests have been carried out; then the relationship of the Italian and European codes, correlating the mechanical properties of the components and the normal compression mechanical property of masonry to its shear mechanical properties (strength and elastic modulus), have been verified. This control has requested also normal compression tests on masonry walls made of the same blocks used for diagonal tests, on the blocks themselves and on the used mortar.
