The behaviour of masonry elements confined with steel tied plates and subjected to axial compression is faced in this paper. The problem is investigated by means of an analytical approach, calibrated against the results of a non linear F.E.M. numerical analysis, carried out with the ABAQUS code. The theoretical procedure allows the evaluation of the effect of confinement in both horizontal directions, accounting for the inelastic behaviour of both masonry and steel. In spite of the reduced number of factors involved, the proposed model proves to be reliable in the prediction of the main behavioural aspects of confined masonry and, for this reason, it can be considered as an useful tool for practical calculations.

Abstract
The behaviour of masonry elements confined with steel tied plates and subjected to axial compression is faced in this paper. The problem is investigated by means of an analytical approach, calibrated against the results of a non linear F.E.M. numerical analysis, carried out with the ABAQUS code. The theoretical procedure allows the evaluation of the effect of confinement in both horizontal directions, accounting for the inelastic behaviour of both masonry and steel. In spite of the reduced number of factors involved, the proposed model proves to be reliable in the prediction of the main behavioural aspects of confined masonry and, for this reason, it can be considered as an useful tool for practical calculations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
