Abstract

A lot of historical masonry buildings are characterized by the presence of slender bearing structures (columns or walls) which exhibit in the main flexural rather than shear behaviour when subjected to a seismic excitation. The equilibrium limit state of such resisting elements is investigated here by the following phases of study: - choice of a suitable a-e constitutive law able to represent experimental results related to different masonry kinds; - consequent modelling of the moment-curvature laws and definition of the equilibrium domain of a column section, assuming the normal compressive load to be constant and the bending moment to be monotonically increasing; - limit analysis of the deflected column by modelling the earthquake ac
