Comportamento de pilares mistos preenchidos com concreto de resíduos de concreto submetidos a compressão axial centrada: efeito do teor de substituição e da forma de aplicação da força
(Universidade Federal de São Carlos, 2020-02-20)
Seeking to mitigate the environmental impact of civil construction, investigations focused on concrete waste use in the production of new concrete are pushing the Brazilian researches. However, despite significant advances ...
Análise de confiabilidade estrutural de pilares mistos de aço e concreto com seção circular preenchida
(Universidade Federal de São Carlos, 2020-02-28)
The developed study deals with the analysis of structural reliability of circular concrete filled steel tube columns under concentric axial load. This type of composite column presents high load capacity when compared to ...
Análise numérica da contribuição da chave de cisalhamento em ligações pilar-viga com consolo e utilizando almofada elastomérica no apoio da viga
(Universidade Federal de São Carlos, 2021-01-25)
This work aims to study the performance of the mechanism with the use of a shear key in column-beam connections, with corbel, and using elastomeric pad at the beam support, and to understand the amount of stress this ...
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 ...
Influência da inclinação de estruturas de cobertura no consumo de madeira
(Universidade Federal de São Carlos, 2022-12-23)
Wood is often used in lattice roof structures because of its excellent mechanical properties.
Currently, due to the increasingly competitive market and the scarcity of available resources,
there has been an increase in ...
Incorporação do resíduo catalítico do refino de petróleo em compósitos cimentícios
(Universidade Federal de São Carlos, 2022-08-16)
The fluidized bed catalytic cracking units seek to improve the efficiency of oil refining to produce lighter compounds with greater added value, using zeolite-based catalysts. The result of this process is the generation ...
Análise numérica de barras compostas em perfis de aço formados a frio submetidas à compressão
(Universidade Federal de São Carlos, 2021-10-21)
Built-up columns are an interesting alternative when isolated channels do not comply with structural performance requirements. During their lifespan, one of the most common stresses in built-up columns is the compression. ...
Contribuição ao estudo de pilares pré-moldados de concreto em etapa transitória
(Universidade Federal de São Carlos, 2022-03-17)
During its production, the precast structures go through different stages called the transitory stage and, consequently, through different static schemes and requests. The precast columns during this stage have a static ...
Análise da resistência ao cisalhamento paralelo às fibras da madeira de acordo com a inclinação dos anéis de crescimento na seção transversal
(Universidade Federal de São Carlos, 2022-02-24)
The shear strength parallel to the fibers (fv0) is quite important, so that it can be verified in the Ultimate Limit State (ULS) of connections (simple shear) and in bending and sheared beams (transverse shear). Wood is ...
Compósitos cimentícios de ultra-alto desempenho reforçados com fibras metálicas e incorporação de pó de vidro
(Universidade Federal de São Carlos, 2022-08-31)
Ultra-high performance fiber-reinforced cementitious composites (UHPFRCC) have been widespread in civil construction due to their rheological, mechanical properties and their improved durability. However, the material has ...
