Avaliação da degradação de vigas reforçadas com FRP quando expostas ao intemperismo
(Universidade Federal de São Carlos, 2019-04-29)
Considering structures natural aging process and also considering externally strengthened elements exposure to aggressive environments (freeze-thaw cycles, temperature, carbonation, ultraviolet radiation, wet-dry cycles, ...
Caracterização de painéis de partículas de madeira tratada com CCB confeccionados com resina poliuretana mista
(Universidade Federal de São Carlos, 2019-02-18)
The particleboard is an engineered product of the wood, made from the gluing of small, deconstructed pieces from the wood processing using a bonding resin. Because it is a material subject to attack by xylophagous organisms, ...
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 ...
Estudo da continuidade de elementos pré-moldados com emendas por luvas grauteadas
(Universidade Federal de São Carlos, 2018-03-07)
The aim of this paper was the validation of the monolithic equivalence applied to precast columns with grouted splice sleeve connections, wherein spliced precast prototypes have been compared with continuous monolithic ...
Relações entre propriedades de rigidez de madeiras do grupo das folhosas
(Universidade Federal de São Carlos, 2019-12-13)
For a correct timber structures design, it is necessary to know the physical and mechanical properties of the material. Among these properties, the modulus of elasticity is highly important, in view of its use in the ...
Modelagem de pilares-parede de concreto armado: estudo paramétrico visando recomendações para o projeto estrutural
(Universidade Federal de São Carlos, 2020-05-06)
Reinforced concrete shear walls, or structural walls, can be a challenge during structural design, due to the non-linear behavior of the materials associated with a geometry of complex analysis. The structural design ...
Estudo numérico-experimental da influência dos mecanismos na resistência à força cortante de lajes alveolares protendidas
(Universidade Federal de São Carlos, 2020-07-14)
The prestressed hollow core slabs present uncertainties regarding the evaluation of the resistance to the resistant shear force. This is because several parameters influence the shear-resistant mechanism of prestressed ...
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 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 ...
