Contribuição ao estudo do comportamento estrutural de terças pré-fabricadas em concreto protendido sem armadura transversal
(Universidade Federal de São Carlos, 2021-07-12)
Purlins are thin beams made without transverse reinforcement and are used in the roofing of precast warehouses. The object of study of this research, were precast concrete purlins, which had been produced by a company in ...
Modelos para a estimativa da resistência característica à tração inclinada de madeiras folhosas
(Universidade Federal de São Carlos, 2022-04-13)
Due to the anisotropic characteristics, wood has distinct mechanical performance when requested in longitudinal, radial and tangential directions. In structural design, the longitudinal direction is considered to be parallel ...
Modelos para estimativas de propriedades físico- mecânicas de espécies de madeiras tropicais em função da densidade aparente e da frequência de vibração transversal
(Universidade Federal de São Carlos, 2022-03-23)
The wood is an excellent material of constructive application, little inserted to the market of the national construction, but with great potential of exploration. This fact is justified not only by restrictions of a ...
Influência do valor médio do módulo de elasticidade à compressão paralela às fibras no projeto de treliças em madeira
(Universidade Federal de São Carlos, 2020-12-18)
In the evaluation of the service limit state, the Brazilian standard ABNT NBR 7190 (1997) recommends the adoption of the mean value of the elasticity module to compression in the direction parallel to grain (Ec0,m) for all ...
Avaliação da correlação entre propriedades colorimétricas e propriedades físico-mecânicas de madeiras tropicais
(Universidade Federal de São Carlos, 2021-10-01)
This work aimed to evaluate the use of colorimetric properties (L*, a* and b*) of the CIELAB system and apparent density as estimators of physical and mechanical properties of ten tropical wood species using quadratic ...
Análise do comportamento de sistemas estruturais em concreto moldado in loco sob o efeito do colapso progressivo
(Universidade Federal de São Carlos, 2020-02-21)
This work aims to investigate the behavior of cast-in-place reinforced concrete structures in the ultimate limit state of collapse. Progressive collapse is the disproportionate spread of a local failure due to the incidence ...
Modelos para a estimativa de propriedades elásticas em materiais compósitos sanduíche de núcleo honeycomb submetidos à flexão
(Universidade Federal de São Carlos, 2024-03-12)
Due to their good mechanical performance combined with a low specific weight, sandwich composite materials have been applied in various situations, especially those with a discontinuous honeycomb core geometry, which has ...
Análise da flambagem de paredes de alvenaria estrutural
(Universidade Federal de São Carlos, 2022-09-01)
This research presents analyzes of slender reinforced masonry walls built with concrete units. The analysis was performed with finite element modeling. The Abaqus computational package was used to develop the models. Slender ...
Estudo do fator de dano acumulado (CDF) de pavimentos aeroportuários brasileiros utilizando FAARFIELD e BAKFAA – Avaliação da incorporação de geogrelhas
(Universidade Federal de São Carlos, 2024-03-23)
Brazilian airport pavements, designed during an era of lower aircraft weights, now face up with challenges due to increased traffic and heavier aircraft, as well as aging infrastructure, predominantly constructed between ...
Estimativa do módulo de elasticidade transversal para madeiras de espécies nativas via ensaios de flexão estática
(Universidade Federal de São Carlos, 2024-03-14)
Wood has been playing a key role in civil construction due to its structural and, especially, sustainable properties. The transverse elasticity modulus (G) is an important elastic property for the proper analysis and ...
