Abstract

The paper is devoted to appraise the effectiveness of existing macro-models in predicting the inelastic behaviour of brick-infilled RC frames under earthquake loading. Frame members are idealised as elastic beams provided with hysteretic springs; filler wall is equated to a couple of crushing diagonal struts. Macro- models are validated by comparing the numerical seismic response to experi- mental time-histories from pseudo-dynamic tests upon one-floor one-bay half- scale specimens. Local damage indices in terms of both measured and computed plastic rotations are correlated to the visible structural damage, being failure at- tained through succeeding cyclic tests. Substantially, it is con
