Modelling, analysis and testing of masonry structures [PDF]

open access: yes, 2006
In this thesis, masonry churches under horizontal actions are studied. Such structures feature strong seismic vulnerability, both because of the mechanical properties of the material and the particular configuration.

A multi-level interface model for damaged masonry [PDF]

open access: yes, 2013
The aim of the present work is to propose a new micro-mechanical model in the context of the deductive approach used to derive interface models. This model, based on a previous study introduced previously by A. Rekik and F.

Masonry Structures [PDF]

open access: yes, 2005
Masonry buildings represent the most widely spread type of structure since the beginning of time until present day. Firstly, stone and wood were used for building, since these materials were easily found in nature, and later elements made out of baked clay, also known as brick. Today, as well as in the past, in the areas of residential, administrative,

RC Beams strengthened with HPFRCC: Experimental and numerical results

open access: yesJournal of Civil Engineering and Management, 2016
The study analyses the behaviour of reinforced concrete beams strengthened with high-performance fibre-reinforced cementitious composite (HPFRCC). Six beams were divided into two equal groups and strengthened.
