Vigas em concreto armado reforçadas com EBR-CFRP submetidas a degradação por temperatura e umidade em condição acelerada
(Universidade Federal de São Carlos, 2021-08-13)
The need to strengthen concrete beams to increase the load capacity due to change not foreseen in the initial project or to problems related to the degradation of this structural system makes the use of composites in Fiber ...
Comportamento de ligações aço-concreto reciclado por meio de adesivos
(Universidade Federal de São Carlos, 2021-08-27)
In a steel-concrete composite members, it’s essential that there is a connection between the materials so that there is a joint behavior that makes them capable of jointly resisting the solicitant efforts. To do this, they ...
Análise numérica de barras compostas em perfis de aço formados a frio submetidas à compressão
(Universidade Federal de São Carlos, 2021-10-21)
Built-up columns are an interesting alternative when isolated channels do not comply with structural performance requirements. During their lifespan, one of the most common stresses in built-up columns is the compression. ...
Aplicação do concreto de ultra alto desempenho em viga pré-moldada protendida para pontes
(Universidade Federal de São Carlos, 2021-08-25)
Several requirements and challenges of modern construction motivated the development of High-Performance Concrete (HPC) and later, with the advance of the research, the Ultra-High Performance Concrete (UHPC). Due to the ...
Estudo sobre a substituição de armadura metálica por barras de GFRP em vigas de concreto armadas à flexão quando submetidas ao ataque acelerado de íons cloreto
(Universidade Federal de São Carlos, 2020-02-28)
The use of reinforced concrete structures with steel bars is recurrent in the construction industry in Brazil. However, alternative materials are studied due to the existence of problems related to the use of this traditional ...
Simulação de comportamento de ligações semirrígidas entre vigas e pilares pré-fabricados por meio de modelagem computacional
(Universidade Federal de São Carlos, 2020-04-16)
This study presents relevant aspects for the adequate use of computational models developed by the finite element method (FEM) as an instrument for investigating the behavior of precast structures, or to complement ...
Durabilidade de vigas de concreto armado reforçadas com mantas de CFRP submetidas a degradação acelerada
(Universidade Federal de São Carlos, 2020-02-27)
Currently, as an alternative to reinforced concrete structures, which have suffered physical or chemical degradation, strengthening systems have been used which use composite materials. Composites are formed by combining ...
Análise do efeito da ação do vento no projeto de edifícios altos de concreto para diferentes sistemas estruturais
(Universidade Federal de São Carlos, 2020-08-28)
The construction of ever taller buildings challenges civil engineers to seek new solutions and structural systems that enable their projects. Ego seems to be the main reason for the construction of huge skyscrapers, which ...
Influência dos modelos idealizados de ligações no dimensionamento de treliças planas de madeira
(Universidade Federal de São Carlos, 2020-10-15)
Throughout human history, wood has been used in numerous ways in civil construction, showing considerable advantages. Among these, sustainability and excellent mechanical properties make it a material widely used in buildings ...
Validação da técnica de macacos planos na avaliação da resistência de alvenaria existente executada com blocos vazados de concreto
(Universidade Federal de São Carlos, 2020-08-27)
The flat jack method is used as non-destructive test, on site, on masonry structures to obtain more accurate data. This method is already standardized internationally by ASTM and RILEM, however, the studies, standards, and ...
