In the present paper, a new d+/d damage model [...]

Abstract

The development of different constructive techniques is somehow conditioned to the investment in scientific research, aiming at comprehend the behaviour of materials; not only as individuals, but also as a whole compound. One area that has growth, for its importance in structural [...]

Abstract

Safety assessment of historic masonry structures is a complex problem mainly due to the mechanical characteristics of their material. In the 50’s it was shown that Standard Limit Analysis is suitable for that type of structures and has proven effectiveness for simplified assessment [...]

Abstract

We formulate a linear programming approach to the limit analysis of discrete element models of masonry structures. Numerical results show the ability of the given procedure to predict the limit value of the multiplier of variable horizontal forces, which are applied to masonry [...]

Abstract

The out-of-plane response is a complex and at the same time key aspect of the seismic vulnerability of masonry structures. It depends on several factors, some of which are the material properties, the quality of the walls, the geometry of the structure, the connections between [...]

Abstract

This paper defines an innovative approach for modelling masonry walls when the structural behaviour of new or existing buildings, subjected to vertical and lateral load, has to be evaluated. Such an approach aims to provide a calculation tool that allows to model the non-linear behaviour [...]

Abstract

This study explores the use of macro-modelling techniques based on smeared crack and damage-plastic constitutive laws for the cyclic in-plane analysis of masonry panels. The numerical investigation is focused on two material macromechanical models, known as Total Strain Cracking [...]

Abstract

Since a few decades, the Discrete Element Modelling (DEM) method has been adopted by many authors as a reliable tool for the structural assessment of unreinforced masonry (URM) structures. In this paper, through compas_dem and using 3DEC by Itasca as a solver in the background, we [...]

Abstract

Brick masonry is a multicomponent composite material, characterized by a marked inhomogeneity, a highly anisotropic behavior arising from the complex interactions between joints and bricks, and a considerable spatial variability of material properties, particularly [...]

Abstract

A computational method is proposed for the lower-bound limit analysis of masonry arches with multiple failure sections. Main motivation is the observation that, not only the position, but also the orientation of the failure sections in an arch might not be known in advance in practical [...]
