Estudo da relação entre sucção, dilatância e resistência ao arrancamento de interfaces areia-geossintético
(Universidade Federal de São Carlos, 2018-03-01)
The interface behavior between soil and geosynthetics plays a key role in reinforced soil structures. The soil-geosynthetic interface resistance, usually obtained by pullout or direct shear tests, is an essential parameter ...
Deformações ao longo do tempo de geossintéticos aplicados a uma estrutura de solo reforçado
(Universidade Federal de São Carlos, 2018-09-03)
In service, excessive deformations can lead a geossynthetic soil reinforced structure to failure or undermine it under operational condition. In the design, usually, because of the uncertainly of the long-term efforts, ...
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 ...
Parâmetros de resistência de RSU: abordagem probabilística para análises de estabilidade de taludes de aterros de resíduos
(Universidade Federal de São Carlos, 2020-02-27)
For landfill designs, the practice of adopting Municipal Solid Waste (MSW) shear strength parameters is often realized based on the values available in the literature, due to the difficulties associated with sampling and ...
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 ...
Avaliação da influência de fibras de polipropileno na resistência efetiva de um solo argiloso
(Universidade Federal de São Carlos, 2019-06-28)
The use of soil-fiber has been recognized as a viable technique of soil improvement in numerous geotechnical applications. However, existing research has not yet established the fundamental mechanisms controlling the ...
Modelagem física de colunas granulares compactadas de RCC parcialmente reforçadas com geossintéticos
(Universidade Federal de São Carlos, 2019-03-14)
Granular Columns has been intensively used as soil improvement for spread footings, embankments and other applications. The filling material of columns is generally crushed stone or sand. However, replacing these natural ...
Avaliação dos fatores que influenciam a hidratação de GCLs em subleitos lateríticos
(Universidade Federal de São Carlos, 2021-04-06)
Currently, the biggest concern in the performance of geosynthetic clay liners (GCLs) applied in municipal solid waste landfills is in the hydration behavior of this material. Recent studies have shown that the GCLs hydration ...
Estudo da distribuição dos reforços em muros portantes de solos reforçados com geossintéticos
(Universidade Federal de São Carlos, 2020-09-01)
Geosynthetic-reinforced structures have been applied to compose bridge abutments carrying loads from bridge structures. In this application, reinforced soil structures have been constructed using reduced spacing between ...
Estimativa da resistência e da rigidez à compressão paralela às fibras pela dureza e pela densidade aparente de espécies de madeira provenientes de florestas nativas
(Universidade Federal de São Carlos, 2022-02-16)
When using wood in structures, it is necessary to know its properties to make a safe and economical structural dimensioning, using the document of ABNT NBR 7190 (1997). However, carrying out the complete characterization ...
