Aplicação do concreto de ultra alto desempenho em viga pré-moldada protendida para pontes
(Universidade Federal de São Carlos, 2021-08-25)
Several requirements and challenges of modern construction motivated the development of High-Performance Concrete (HPC) and later, with the advance of the research, the Ultra-High Performance Concrete (UHPC). Due to the ...
Comportamento de blocos estruturais de concreto com diferentes agregados sob altas temperaturas
(Universidade Federal de São Carlos, 2022-10-24)
The present work aims to investigate, in laboratory, of structural concrete blocks submitted to high temperatures to contribute with relevant information for the design of structural masonry in a fire situation. Since ...
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 ...
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 ...
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. ...
Estimativa de propriedades mecânicas de madeiras de Eucalipto em função de parâmetros físicos e anatômicos
(Universidade Federal de São Carlos, 2022-12-16)
Exotic species introduced in Brazil have been of great interest to the civil construction industry because, among their advantages, they have rapid growth and provide sustainability for intensively exploited native species. ...
Influência dos modelos de carbonização na análise não linear geométrica de treliças de madeira em situação de incêndio
(Universidade Federal de São Carlos, 2022-04-27)
In this work, a numerical study about the geometric nonlinear analysis of plane timber trusses in fire situations was carried out. The analysis was based on a positional formulation of the finite element method. The effects ...
Estimativa das propriedades físico-mecânicas de madeiras tropicais brasileiras através da análise de porosimetria por intrusão de mercúrio
(Universidade Federal de São Carlos, 2022-02-16)
Full wood characterization tests require expensive and large equipment, found only in research centers and, moreover, require time and skilled labor. Thus, the minimal and simplified characterization are a tool widely used ...
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 ...
