Relações entre propriedades de rigidez de madeiras do grupo das folhosas
(Universidade Federal de São Carlos, 2019-12-13)
For a correct timber structures design, it is necessary to know the physical and mechanical properties of the material. Among these properties, the modulus of elasticity is highly important, in view of its use in the ...
Análise do comportamento estrutural e durabilidade de pilares de concreto armado reforçados com manta de GFRP
(Universidade Federal de São Carlos, 2019-04-26)
Fiber reinforced polymers (FRP) are an attractive option for the strengthening of structures in the civil construction due to the intrinsic characteristics of the system, e.g., lower self-weight, ease and versatility of ...
Contribuição para determinação do módulo de deformação à compressão de aparelhos de apoio elastoméricos simples
(Universidade Federal de São Carlos, 2019-06-25)
The elastomers, also known as neoprene, have been widely used in the precast concrete constructions in Brazil, due to its good performance in connections subjected to compression. Thus elastomeric bearing pads are the most ...
Análise de sensibilidade entre modelos de cálculo de resistência à força cortante de lajes alveolares pré-fabricadas protendidas
(Universidade Federal de São Carlos, 2019-08-30)
Regarding the constant increase in systems using precast members, specially prestressed hollow-core slabs, due to cost and schedule reduction, it was necessary to review past researches related to the shear capacity of ...
Estudo da continuidade de elementos pré-moldados com emendas por luvas grauteadas
(Universidade Federal de São Carlos, 2018-03-07)
The aim of this paper was the validation of the monolithic equivalence applied to precast columns with grouted splice sleeve connections, wherein spliced precast prototypes have been compared with continuous monolithic ...
