Modelling the Dynamics of Masonry Structures with Discrete Elements

Block models have been shown to provide a realistic representation of the behavior of many types of masonry structures under static and dynamic loads. When the strength of the units is such that movements along the joints govern the behavior, it is acceptable to make the simplifying assumption that blocks act as rigid bodies. This assumption is particularly useful when dealing with seismic prob...

Adaptive Finite Elements for Reinforced Concrete Framed Structures

Abstract. This work focuses on the modelling of nonlinear response of reinforced concrete structures by means of the finite element method. A new technique which employs a variable mesh in order to reduce the computational cost of classical approaches is presented. For some piecewise linear constitutive models which are widely employed for the modelling of reinforced concrete, some properties o...

Modal Analysis of Masonry Structures

This paper presents a new numerical tool for evaluating the vibration frequencies and mode shapes of masonry buildings in the presence of cracks. The algorithm has been implemented within the NOSA-ITACA code, which models masonry as a nonlinear elastic material with zero tensile strength. Some case studies are reported, and the differences between linear and nonlinear behaviour highlighted.

A 2D typology generator for historical masonry elements

The mechanical response of stone masonry depends on the properties of the components and also on the typology created by the stone units and the mortar joints. While the influence of the component strength on masonry is relatively well studied, mainly due to the difficulty of varying the masonry typology systematically, few research studies have been devoted to its influence on masonry properti...
