The research work concerns the seismic vulnerability assessment of masonry bell towers in Italy, which is performed by comparing full non-linear dynamic analysis and non-linear static analysis. The seismic response of these structures involves a coupling between flexural and axial vibration modes, the presence of shear damage patterns, and high vibration modes causing the belfry collapse. The problem is simplified by using a plane 2D scheme. A specific Rigid Body and Spring Model is adopted to describe the in-plane dynamics including the main meso???scale damage mechanisms, by means of proper constitutive laws.

Abstract
The research work concerns the seismic vulnerability assessment of masonry bell towers in Italy, which is performed by comparing full non-linear dynamic analysis and non-linear static analysis. The seismic response of these structures involves a coupling between flexural and axial vibration modes, the presence of shear damage patterns, and high vibration modes causing the belfry collapse. The problem is simplified by using a plane 2D scheme. A specific Rigid Body and Spring Model is adopted to describe the in-plane dynamics including the main meso???scale damage mechanisms, by means of proper constitutive laws.File in questo prodotto:
