In-plane performance of unreinforced and reinforced masonry were tested in a quasi-statical fashion, by loading perforated brickwork walls with in-plane constant normal force and increasing lateral force up to the collapse. Fifteen full-scale walls with openings were constructed by professional bricklayers, from recovered bricks and lime-mortar, following ancient rules. Six different FRP reinforcements of the walls were tested. Tests and analyses results show that the in-plane ultimate capacity of the unreinforced walls are extre¬m-ely greater than seismic codes recognizes; and that FRP reinforcement drastically enhances the in-plane ultimate capacity, but the lateral strength of current codes is significantly lower even than the test results of the same but unreinforced walls.

Abstract
In-plane performance of unreinforced and reinforced masonry were tested in a quasi-statical fashion, by loading perforated brickwork walls with in-plane constant normal force and increasing lateral force up to the collapse. Fifteen full-scale walls with openings were constructed by professional bricklayers, from recovered bricks and lime-mortar, following ancient rules. Six different FRP reinforcements of the walls were tested. Tests and analyses results show that the in-plane ultimate capacity of the unreinforced walls are extre¬m-ely greater than seismic codes recognizes; and that FRP reinforcement drastically enhances the in-plane ultimate capacity, but the lateral strength of current codes is significantly lower even than the test results of the same but unreinforced walls.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
