Experimental and Computational Evaluation of In-Span Hinges in Reinforced Concrete Box-Girder Bridges
(ASCE-AMER SOC CIVIL ENGINEERS, 2011)
During the last three decades, considerable research efforts have sought to improve the seismic design of California highway bridges. However, the in-span hinge (ISH) regions of concrete box girders have not been studied ...
Parametric Study and Design Recommendations for In-Span Hinges in Reinforced Concrete Box-Girder Bridges
(ASCE-AMER SOC CIVIL ENGINEERS, 2012)
In-span hinges (ISHs) are located at the bridge deck of reinforced concrete box-girder bridges and are used to transmit vertical loads between two adjacent parts of the deck. ISHs are disturbed regions because of the complex ...
Estudo dos esforços atuantes em uma ponte em concreto armado
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2016-06-20)
Bridges are structures of extreme importance to the development of a region. Therefore, there is a need for a deeper study of the mechanical behavior, to seek faster, cheaper, durable and safer solutions. Based on this, a ...
Verificação à fadiga de vigas de pontes de concreto armado: estudo comparativo entre o uso do trem-tipo normativo e as cargas reais nas rodovias brasileiras
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2019-12-11)
Bridges and viaducts are important in the social and economic dynamics of a nation, and they are very important elements in transportation systems. In Brazil, freight transportation is predominantly by road. Therefore, ...
