Análise de sensibilidade entre modelos de cálculo de resistência à força cortante de lajes alveolares pré-fabricadas protendidas
(Universidade Federal de São Carlos, 2019-08-30)
Regarding the constant increase in systems using precast members, specially prestressed hollow-core slabs, due to cost and schedule reduction, it was necessary to review past researches related to the shear capacity of ...
Contribuição para determinação do módulo de deformação à compressão de aparelhos de apoio elastoméricos simples
(Universidade Federal de São Carlos, 2019-06-25)
The elastomers, also known as neoprene, have been widely used in the precast concrete constructions in Brazil, due to its good performance in connections subjected to compression. Thus elastomeric bearing pads are the most ...
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 ...
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 ...
Algoritmo genético como ferramenta auxiliar no pré-dimensionamento de estruturas protendidas
(Universidade Federal de São Carlos, 2019-08-29)
Considering the need of searching for more suitable solutions on the Civil and Structural Engineering ambit, this current research aims to assess the efficiency of the Genetic Algorithm when applied as an auxiliary tool ...
Avaliação da relação entre a resistência ao cisalhamento e a resistência à compressão paralela às fibras de madeiras do grupo das folhosas
(Universidade Federal de São Carlos, 2019-08-12)
Wood presents several advantages when compared with other materials employed in the civil construction sector. In Brazil, the standard ABNT NBR 7190: 1997 establishes test methods to determine physical and mechanical ...
Avaliação da degradação de vigas reforçadas com FRP quando expostas ao intemperismo
(Universidade Federal de São Carlos, 2019-04-29)
