Durabilidade de argamassas submetidas ao ataque de sulfatos : efeito da adição da nanosílica
(Universidade Federal de São Carlos, 2018-03-28)
Durability is one of the characteristics to be considered in design and projects of concrete structures as it is related to the useful life of buildings. Among the aggressive agents most damaging to the concrete are sulfate ...
Relação entre módulos de elasticidade de peças estruturais e de corpos de prova de madeiras tropicais
(Universidade Federal de São Carlos, 2018-03-07)
In terms of sustainability and civil construction, wood, a natural, renewable and easily obtainable material, has a good relation between resistance and density, and due to its versatility, it is an excellent alternative ...
Modelagem numérica do comportamento estrutural de vigas mistas de aço e concreto protendidas
(Universidade Federal de São Carlos, 2018-06-15)
The structural behavior of the prestressed steel concrete composite beams was investigated using the Finite Element Method. The present study reports two types of composite beams: steel beams and concrete slab with joint ...
Análise de laje alveolar protendida moldada por fôrma fixa e usando placas de poliestireno expandido - Estudo teórico e experimental
(Universidade Federal de São Carlos, 2018-06-18)
The use of prestressed hollow core slabs has increased significantly and, consequently various productive methods have emerged. These methods do not employ machinery such as extruders or slip former machine. In this research, ...
Modelagem numérica de piso misto de aço e concreto de pequena altura: ênfase à ligação viga-pilar
(Universidade Federal de São Carlos, 2018-06-22)
The demand and use of the floor and concrete system has been mainly due to good characteristics and constructive systems that associate steel and concrete. A slim floor composite is defined for the floor system whose beam ...
Procedimentos e resultados de ensaios de caracterização física e mecânica de blocos cerâmicos estruturais e de vedação
(Universidade Federal de São Carlos, 2018-04-26)
In Brazil ceramic blocks are widely used in masonry constructions and their quality is guaranteed by the Brazilian standard ABNT NBR 15270. This standard went through a revision process in the year 2017 and this research ...
Implementação das ações de protensão em programa de grelha equivalente
(Universidade Federal de São Carlos, 2018-04-24)
This research studies the prestress effect on structures of flat plate and beams of concrete. The work consisted of coupling a computational subroutine in the already existing platform, the CALCO. Currently the system ...
Análise dos efeitos da interação solo-estrutura em edifícios estruturados em aço
(Universidade Federal de São Carlos, 2018-05-18)
The present work presents a comparative study between different steel structures on shallow foundations (single footing) and deep foundation (piles) with the purpose of identify the effects of the consideration of the ...
Estudo sobre aderência entre barras de aço e concreto autoadensável com baixo consumo de cimento
(Universidade Federal de São Carlos, 2018-03-02)
Cement consumption at global level increases gradually, so too grows the environmental degradation that the construction generates. In this scenario, the search for rationalization of materials becomes important. Self-compacting ...
Produção de concretos autoadensáveis com baixo consumo de cimento e sua influência na aderência aço-concreto
(Universidade Federal de São Carlos, 2018-10-25)
Self-compacting concrete (SCC) must simultaneously exhibit high fluidity, cohesion and absence of segregation. However, the maintenance of these properties in the fresh state requires a greater consumption of binders and ...
