Ensaios de ondas ultrassônicas e redes neurais artificiais na avaliação da resistência à compressão do concreto
(Universidade Católica de Pernambuco, 2010-09-10)
Stripping of formworks in reinforced concrete structures can only be done when concrete is hardened enough to carry the loads without generating unacceptable deformations. These are two important demands from Brazilian ...

Comportamento estrutural de edificações de concreto de múltiplos pavimentos considerando o efeito construtivo
(Universidade Católica de Pernambuco, 2015-12-29)
The building industry has experienced in recent years a strong growth in demand in general and in the case of reinforced concrete buildings this increase has been more marked. This fact has also contributed to accelerate ...

Parametric model for the analysis of concrete expansion due to alkali-aggregate reaction
(PROFESSIONAL ENGINEERING PUBLISHING LTD, 2008)
The alkali-aggregate reaction (AAR) is a chemical reaction that provokes a heterogeneous expansion of concrete and reduces important properties such as Young's modulus, leading to a reduction in the structure's useful life. ...
Análise comparativa do módulo de elasticidade calculado segundo diferentes normas
(Universidade Católica de Pernambuco, 2014-06-09)
The work involved studying the behavior and adjustment of dosage diagram of concrete with respect to static and dynamic elastic modulus. Furthermore, it compares the models of the static elastic modulus based on the ...
Eficiência de ligação semirrígida aplicada em concreto pré-moldado
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2018-12-12)
The adoption of construction systems, based on precast concrete, is recurrent in structures built in Brazil. With the adoption of precast concrete structures in buildings, that are increasingly slender or that seek a ...
