Simplified indexes for the seismic assessment of masonry buildings : internatio...

Heritage masonry buildings are particularly vulnerable to earthquakes because they are deteriorated and damaged, they were built with materials with low resistance, they are heavy and the connections between the various structural components are often insufficient. The present work details a simplified method of seismic assessment of large span masonry structures that was applied to a database of forty-four mon...

Reinforced brick-masonry light vaults : semi-prefabrication, construction, test...

This work deals with short to mid span-length light vaults made of reinforced brick-masonry. The research is oriented at proposing semi-prefabrication and construction techniques. Numerical models for predicting the structural behavior of this type of structures are developed. Experimental research is performed with the following three main objectives: (i) validating the proposed construction techniques, (ii) i...

Developing innovative systems for reinforced masonry walls

The Commission of the European Communities has recently funded a CRAFT research project aimed at developing innovative systems for load and non-load-bearing reinforced masonry walls. The project involves twelve partners coming from four different European countries, among which there are universities and research centres, small and medium enterprises for the production of clay and concrete units and mortars, a ...

Investigations techniques carried out on the Qutb Minar, New Delhi, India

In the framework of the Eu-India Economic Cross Cultural Programme “Improving the Seismic Resistance of Cultural Heritage Buildings”, aimed at the preservation of ancient masonry structures with regard to the seismic risk, different NDT were applied to the Qutb Minar, New Delhi, India, in September 2005. The paper describes the different investigation techniques applied (Ambient Vibration and Pulse Sonic Veloci...

Dynamic identification of the Qutb Minar, New Delhi, India

Experimental investigation on the structural behaviour and strengthening of thr...

A large part of historical structures, currently in the European urban centres, is built with stone masonry walls, frequently constituted by multiple leaves. A common typology encountered is the three-leaf stone masonry wall, which is characterized by a substantial presence of voids in the inner leaf and prone to brittle collapse mechanisms. Nevertheless, the knowledge of the mechanical behaviour of three-leaf ...

Reducing the seismic vulnerability of cultural heritage buildings

Urbanização da leishmaniose visceral em Belo Horizonte

O Brasil vivencia na atualidade uma situação na qual velhas endemias, que se pensava esquecidas, ressurgem com grande impacto e muitas vezes com perfis de morbi-mortalidades diferentes daqueles já conhecidos. Este é o caso da leishmaniose visceral, uma doença caracteristicamente rural e associada a condições precárias de vida, que encontra no espaço urbano ambiente favorável para se estabelecer e desenvolver. O...

Uso da terra como determinante da distribuição da raiva bovina em Minas Gerais,...

Realizou-se um estudo observacional retrospectivo com o objetivo de avaliar variáveis do uso da terra como determinante da distribuição da raiva bovina em Minas Gerais. Foram analisadas 7.526 fichas de diagnóstico de raiva por imunofluorescência direta, de 1976 a 1997. Utilizaram-se os dados dos Censos Agropecuários de Minas Gerais- FIBGE, anos de 1970, 1985 e 1995-1996. Empregou-se o método da análise fatorial...

Distribuição temporal e espacial da raiva bovina em Minas Gerais, 1976 a 1997

Realizou-se um estudo observacional retrospectivo com o objetivo de avaliar a distribuição espaço-temporal da raiva bovina em Minas Gerais. Foram analisadas 7.526 fichas de diagnóstico de raiva por imunofluorescência direta, de 1976 a 1997. Para distribuição espacial da raiva bovina foi utilizado o aplicativo de mapeamento MAP-INFO Professional 4.5. Foi observada tendência crescente anual não só de diagnósticos...
