Abstract
In recent decades the composite materials have been used to strengthened and repair the historical masonry. A new class of composites that is begin explored that includes steel fiber sheet embedded in an inorganic matrix. The use of steel fibers was proposed in alternative to others fibers as PBO, Carbon glass and Basalt. In the paper, the structural behavior of masonry columns strengthened with steel-FRCM (SRG) have been investigated through the numerical 3D simulations calibrated on experimental tests present in literature. The 3D numerical approach is based on a macro-model to simulate the nonlinear structural behavior masonry columns. The comparison of the numerical models with the experimental carryout shows in terms of peak force and axial force–strain curves.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
