The influence of service temperature on bond between FRP reinforcement and concrete
No full textThe interest in fibre reinforced polymer (FRP) reinforcement in construction has considerably increased and especially the application of FRP as externally bonded reinforcement (FRP EBR) has become more and more established. The use of FRP EBR has been adopted world-wide as a very attractive technique for
structural strengthening and rehabilitation. At Ghent university, the fire behaviour of slabs and beams strengthened with advanced composites, including the use of fire protection systems, has been investigated. In addition, the behaviour of the FRP-concrete interface at increased temperatures has been
considered, as elevated temperatures may occur during service conditions, especially for outdoor applications. According to fib Bulletin 14, the glass transition temperature of the adhesive used to bond the FRP should equal 20°C in excess of the maximum ambient temperature at normal service conditions,
and should be at least 45°C. When reaching the glass transition temperature, the properties of the adhesive decrease to a large extend and bond interaction between the concrete and the external FRP reinforcement may be completely lost.
To study the bond behaviour at elevated temperatures, a joint test program between the Universities of Ghent and Lecce has been executed, comprising a series of 20 bond tests performed at the Magnel Laboratory for Concrete Research. The present paper will discuss the experimental work and the main test results obtained
Tension stiffening of RC Ties Strengthened with externally bonded FRP Sheets
No full textExternally bonded laminates of fiber reinforced polymers ~FRPs! are becoming more and more common for rehabilitation and
strengthening of RC structures, to solve problems either in serviceability or at ultimate conditions. This paper focuses on the behavior in
the serviceability state: in particular, verifications in terms of cracks widths and crack spacing, used to warrant the functionality of
FRP-RC structures, are considered. Test results on RC ties externally reinforced with FRP laminate are reported and the applicability of
the Eurocode2 formulation used for RC elements is discussed. Provisions given by the International Federation for Structural Concrete are
also analyzed
The effect of irrigated urban agriculture on malaria, schistosomiasis and soil-transmitted helminthiasis in different settings of Côte d'Ivoire
No full textMalaria is responsible for more than one million deaths every year, mainly children under the age of five years living in sub-Saharan Africa. At least one billion people harbor one or several of the three main soil-transmitted helminths, namely Ascaris lumbricoides, hookworms and Trichuris trichiura, and about 207 million people are infected with schistosomes. An estimated 70,000 people die each year from amoebiasis, caused by Entamoeba histolytica. Giardiasis, caused by Giardia duodenalis, is responsible for 2.8 million annual infections. Poor rural and urban communities in developing countries bear the highest burden of the above-mentioned diseases. Their causes are multifactorial including lack of access to clean water, improved sanitation and health services, as well as inadequate treatment, protection and prevention. The highest rates of urbanization currently occur in the less developed regions of Africa and Asia, and it is predicted that the majority of the population will be living in small and medium urban centers in the near future. The maintenance of traditional livelihoods, including agriculture, is a typical feature in urban settings across Africa, especially in small towns where population densities and land pressure are lower than in big cities. Urban agriculture contributes to food security and livelihood opportunities for poor urban dwellers. However, the adaptation of disease vectors and intermediate hosts to urban ecosystems has been observed, which might further enhance the negative effects associated with persistent rural lifestyles. For example, the creation of malaria vector breeding sites and contact with contaminated water and soil in areas of irrigated agriculture may increase the transmission of vector-borne, water-related and soil-transmitted parasitic diseases. This PhD focused on the interface of agriculture and human health in two different urban settings of Côte d’Ivoire. The overarching goal was to contribute to a better understanding of the effects of irrigated urban agriculture on the transmission of malaria, schistosomiasis, soil-transmitted helminthiasis and intestinal protozoan infections. The research entailed a considerable amount of fieldwork, carried out between April 2004 and July 2005. In a first step, six zones of irrigated agricultural land use were identified both in Abidjan, the economic capital of Côte d’Ivoire (3.3 million inhabitants), and in the mediumsized town of Man (115,000 inhabitants) in the western part of the country. Next, two standardized mosquito breeding site assessments were conducted in these agricultural zones in the rainy season (September 2004) and in the dry season (February 2005). In each urban setting, a minimum of 120 farming households and additionally 30 non-farming households were randomly selected. Geographic coordinates of houses and the main agricultural plots were recorded. Name, age and sex of all household members were registered. In October
2004, interviews on agricultural land use, farming practices and water storage were
conducted with the heads of the farming households. In a cross-sectional survey done in
May/June 2005, questionnaires were administered to all households to assess the socioeconomic
status, sanitary facilities and common water contact patterns. From each study
participant, a finger prick blood sample and a stool sample were collected. Thick and thin
blood films were stained with Giemsa and examined for Plasmodium spp. under a light
microscopy. The stool samples were prepared based on the Kato-Katz technique and eggs of
Schistosoma mansoni, A. lumbricoides, hookworm and T. trichiura were recorded separately.
Cysts or trophozoites of intestinal protozoa, including Entamoeba histolytica/E. dispar and G.
duodenalis were identified using an ether-formalin concentration method. Risk factors were
identified by fitting multivariate non-random and random effects Bayesian regression models
integrating spatial correlation of infection.
Agricultural land use in Abidjan was characterized by market gardens on lagoon shores
and high-yield vegetable production. The vegetable production areas in Abidjan developed as
a consequence of land access difficulties in unexploited public and private areas near poor
settlements, mainly at lagoon shores. In Man, farming was family- and subsistence-based.
Predominant agricultural activities were traditional irrigated rice farming and vegetable
production in lowlands and along the Kô River.
The typical demographic and socio-economic profile of a vegetable producer in
Abidjan is that he is an immigrant from Burkina Faso, illiterate and lacking a professional
agricultural training. Malaria and intestinal parasitic infections were most prevalent among
the final study cohort of 370 farmers and family members from 121 farming households. We
found overall prevalences of T. trichiura, P. falciparum and hookworm of 42.6%, 24.3% and
17.3%, respectively. The parasites were heterogeneously distributed between the six market
garden zones. Prior health issues were suppressed by the farmers with the daily livelihood
struggle and reported symptoms due to intestinal parasitic infections were of less importance
when compared to malaria. In-depth focus group discussions revealed that the working
environment was discerned as unhealthy, and waste dumps and human defecation grounds
were perceived as main health risks. Farmer communities and their network are indicative for
the degree of social coherence and stability in a vegetable production area because these
zones are characterized by highly dynamic land use patterns.
In the town of Man, Anopheles larvae were present in 50.7% and 42.4% of 369 and 589
examined potential mosquito breeding sites in the rainy and in the dry season, respectively.
The most productive habitats were man-made, i.e. agricultural trenches, irrigation wells, and
flooded and recently transplanted rice plots. The overall prevalence of P. falciparum
infections in the final study cohort of 574 individuals from 112 farming households was
32.1%. Risk factors for P. falciparum in children <15 years of age included living in specific
agricultural zones (i.e. traditional irrigated rice plots, mixed crops and a large rice perimeter),
proximity to permanent man-made ponds and fish ponds, periodic stays overnight in farm
huts and low socio-economic status.
The final study cohort for S. mansoni and soil-transmitted helminthiasis comprised 586
individuals from 113 farming households. The overall prevalences of S. mansoni, hookworm,
E. histolytica/E. dispar and G. duodenalis were 51.4%, 24.7%, 20.2% and 6.3%, respectively.
Members from farming households harbored significantly more often an infection with
E. histolytica/E. dispar and G. duodenalis when compared to non-farming households.
Predictors for an S. mansoni infection included close proximity to the Kô River, contact with
irrigation wells and ponds on the agricultural plots and low educational attainment. Risk
factors for hookworm infection comprised living in agricultural zones of traditional
smallholder irrigated rice plots and a large rice perimeter, using water from domestic wells
and low socio-economic status. Infection prevalences of P. falciparum, S. mansoni and
hookworm were spatially highly heterogeneous between the agricultural zones and highest
infections occurred in a zone of a large rice perimeter. P. falciparum infection intensity and
hookworm infection prevalence were best explained by spatial random effect models. Spatial
correlation between farmers’ houses was not significant.
The findings of the present work illustrated a clear picture of the interconnections
between specific irrigated agricultural land use and agricultural activities, and malaria and
intestinal parasitic infections in different urban settings of Côte d’Ivoire. The outcomes lead
to an enhanced understanding of their epidemiology in local agro-ecological urban settings
and related contextual determinants (i.e. agricultural, behavioural, demographic, socioeconomic
and environmental factors) and allows the design of readily adapted prevention and
control interventions (e.g. tangible vector control strategies and prevention measures for
helminth infections) which actively involve farming communities in the subsequent
implementation and control management
Debonding strength and anchorage devices for reinforced concrete elements strengthened with FRP sheets
No full textA brief overview of anchorage systems is dealt with introducing experimental tests on eight types of end fixing for reinforced polymers
(FRP) sheets glued on RC elements. Particular test set-up and T-shaped specimens have been designed and realized to test mechanical
fixings with steel or FRP plates glued or bolted, FRP bars or L-shaped fibers. The experimental results confirm that the various solutions
have different performances in improving the debonding load. Numerical analysis confirm the reliability of debonding formulations
available; furthermore a simple evaluation of anchorage effectiveness is proposed
