The flat jack test on masonry walls (previously subjected to experimental trials) has been numerically simulated using a finite element non-linear computer program. A failure criterion was adopted such as to closely resemble the envelope of experimental resistance domains (obtained by other Authors), that vary depending on the inclination of the principal stresses to the bed jointing plane. Results obtained are generally in agreement with experimental findings, which proves the numerical model used to be reliable. Consequently, numerical analyses highlighted some aspects of the test, which had gone unnoticed in the laboratory and which contribute to a more accurate interpretation of the test itself.

Abstract
The flat jack test on masonry walls (previously subjected to experimental trials) has been numerically simulated using a finite element non-linear computer program. A failure criterion was adopted such as to closely resemble the envelope of experimental resistance domains (obtained by other Authors), that vary depending on the inclination of the principal stresses to the bed jointing plane. Results obtained are generally in agreement with experimental findings, which proves the numerical model used to be reliable. Consequently, numerical analyses highlighted some aspects of the test, which had gone unnoticed in the laboratory and which contribute to a more accurate interpretation of the test itself.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
