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 ...
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 ...
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 ...
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 ...
Procedimento para análise de fundação de radier considerando grelha e apoios elásticos
(Universidade Federal de São Carlos, 2019-03-26)
The calculation of flexible or rigid mat foundation is difficult to perform because it is a matter of analyzing a plate resting on the ground, subjected to the external actions and the reactions of the soil. Following a ...
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, ...
Tração mobilizada de reforços geossintéticos sob condições operacionais e efeito de umedecimento
(Universidade Federal de São Carlos, 2019-03-15)
The use of low permeability fine local soils instead of granular materials has been common in several countries due to the significant reduction of the costs associated with the transport of granular materials extracted ...
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 ...
