This work presents a mechanical model and a shape optimization procedure for masonry elements such as vaults, domes and walls. The adopted mechanical model is based on the representation of the stress field carried by the structure through a discrete network of compressed (masonry) struts and tensile members corresponding to strips of fiber reinforced composites bonded to the masonry substrate. A topology optimization of such a tensegrity model is formulated, on accounting for a minimal mass design strategy; different yield strengths of the masonry struts and tensile reinforcements; and multiple loading conditions. We show that the given optimization strategy can be profitably employed to rationally design fiber-reinforced composite material reinforcements of existing or new masonry structures, making use of the safe theorem of limit analysis. A wide collection of numerical examples dealing with real-life structures highlight the technical potential of the proposed approach

Abstract

This work presents a mechanical model and a shape optimization procedure for masonry elements such as vaults, domes and walls. The adopted mechanical model is based on the representation of the stress field carried by the structure through a discrete network of compressed (masonry) struts and tensile members corresponding to strips of fiber reinforced composites bonded to the masonry substrate. A topology optimization of such a tensegrity model is formulated, on accounting for a minimal mass design strategy; different yield strengths of the masonry struts and tensile reinforcements; and multiple loading conditions. We show that the given optimization strategy can be profitably employed to rationally design fiber-reinforced composite material reinforcements of existing or new masonry structures, making use of the safe theorem of limit analysis. A wide collection of numerical examples dealing with real-life structures highlight the technical potential of the proposed approach
