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 ...
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 ...
Análise do comportamento de sistemas estruturais em concreto moldado in loco sob o efeito do colapso progressivo
(Universidade Federal de São Carlos, 2020-02-21)
This work aims to investigate the behavior of cast-in-place reinforced concrete structures in the ultimate limit state of collapse. Progressive collapse is the disproportionate spread of a local failure due to the incidence ...
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 ...
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 ...
Análise numérica de lajes alveolares protendidas submetidas ao esforço cortante com a presença de aberturas
(Universidade Federal de São Carlos, 2020-12-11)
The use of prestressed precast hollow core slabs has intensified as technological advances, and as part is manufactured in industry, this element needs adjustments during its application, as for example, when need openings ...
Influência do valor médio do módulo de elasticidade à compressão paralela às fibras no projeto de treliças em madeira
(Universidade Federal de São Carlos, 2020-12-18)
In the evaluation of the service limit state, the Brazilian standard ABNT NBR 7190 (1997) recommends the adoption of the mean value of the elasticity module to compression in the direction parallel to grain (Ec0,m) for all ...
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 ...
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 ...
