Adobe is a traditional masonry made of sundried earthen bricks and mud mortar. Despite a millennial history of buildings of architectural value, adobe still connotes a so called ‘not engineered’ construction type. Namely, the material and structural properties of adobe are still

Dynamic behaviour of adobe bricks in compression
The role of fibres and water content at various loading rates
This paper presents the results of an experimental research aimed at assessing the material performance of adobe bricks in compression for a wide range of induced strain rates, from statics to high velocity impact. Adobe connotes a traditional masonry whose bricks are made of sun

Dynamic simulations of traditional masonry materials at different loading rates using an enriched damage delay
Theory and practical applications
A local damage model has been recently developed for the numerical simulation of the static behaviour of adobe bricks. Mesh insensitivity of the local model was obtained by generalizing the damage delay concept based on a Dirichlet boundary condition decomposition integrated in a

The Adobe delta damage model
A locally regularized rate-dependent model for the static assessment of soil masonry bricks and mortar
A local damage model is proposed for the numerical assessment of the static performance of Adobe masonry components. The model was applied to simulate the experimental behaviour of sundried soil bricks and mud mortar tested in uniaxial compression and bending. Numerical simulatio

Dynamic simulation of masonry materials at different loading velocities using an updated damage delay algorithm of regularization
Theory and practical applications
Buildings and structures in many cities have recently been exposed to an increased number of highly dynamic hazards. These include not only floods and earthquakes but also man made threats such as ballistic impacts and blasts. Thus, the assessment of the dynamic performance of st

Experimental-numerical material characterization of adobe masonry
Tests and simulations on various types of earthen bricks and mortar in statics and dynamics
Research in this thesis is aimed at comprehensively characterizing the mechanical performance of adobe components. Adobe is a traditional masonry made of sundried bricks and mortar. Bricks are made of soil mixed with fibres and joined together by mud mortar. Adobe is largely spre

Dynamic characterization of adobe in compression
The influence of fibre fraction in soil mixtures
Adobe is one of the most ancient forms of masonry. Adobe bricks are sundried mixtures of clay, silt, sand and natural fibres locally available joined together using mud mortar. Adobe structures are largely spread in areas of the world prone to earthquakes or involved in military

Housing by people and work
Design principles for favelas residents in economies of commerce and service
This article proposes a new approach towards the design and planning of social housing destined to residents living in informal settlements of Brazil. It is aimed at restoring the proximity between the labor and domestic functions within the spatial domain of the house. This need

The mechanical performance of traditional adobe masonry components
An experimental-analytical characterization of soil bricks and mud mortar
Adobe is an ancient building technology made of sun dried bricks joined together by mud mortar. This paper deals with the physical and mechanical characterization of three different typologies of adobe bricks and one typology of mud mortar produced in Europe. They differed in ter

A local damage model has been developed for interpreting the dynamic performance of Adobe, a traditional form of masonry whose components are made of sun-dried and unpressed soil possibly reinforced with fibres. This paper presents a numerical model to assess the static performan

Ballistic model for the prediction of penetration depth and residual velocity in adobe
A new interpretation of the ballistic resistance of earthen masonry
In this paper, a new one-dimensional phenomenological model is developed for the assessment of the ballistic performance of Adobe. Adobe is a masonry largely spread in areas of the world involved in military operations. Addressing fundamental ballistic parameters such as residual

Operative Guidelines for Protection of Places of Worship from Terrorist Attacks
A new approach toward security design of sensitive buildings
The present thesis is aimed at defining operative guidelines devoted to the prevention and limitation of disastrous consequences for man's life and property in case of terrorist attacks perpetrated in places of worship. These guidelines are meant to be applied by governs of Weste
