A plastic damage approach for confined concrete
(Pergamon-Elsevier Science Ltd, 2005-10)
There are many situations in which it is necessary to increase the capacity of structures in use. This need maybe either for a change of use or because the structures have suffered some damage or have shown little resistance ...
Conectores Composite Dowels aplicados a pilares mistos de seção tubular de aço esbelta
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ESTRUTURASPrograma de Pós-Graduação em Engenharia de EstruturasUFMG, 2021-12-14)
The objective of this study is to evaluate the application of Composite Dowels connectors when used as load introduction devices in concrete-filled steel columns (CFSC), in which the circular tubular sections have a high ...
Pullout strength of axially loaded steel rods bonded in glulam at a 45º angle to the grain
(ABM, ABC, ABPol, 2009)
This paper presents an experimental analysis of the pullout strength of bonded and axially loaded steel rods used as connector elements in log-concrete composite bridge decks. Static and cyclic tests were carried out to ...
Estudo numérico de um dispositivo de transferência de cargas em pilares mistos tubulares preenchidos com concreto
(Universidade Federal de Minas GeraisUFMG, 2012-05-09)
In Brazil, Standard Draft for design of steel and composite structures of steel and concrete with tubular, circular and rectangular profiles (PN 02 125.03-004) is on its final stages of development. This work aims at ...
Estudo do dimensionamento de pilares de aço tubulares e pilares mistos de perfis tubulares preenchidos com concreto de acordo com a ABNT NBR 16239:2013
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2014)
The use of steel hollow sections as well concrete filled steel hollow sections for columns are an interesting solution for the civil construction. Due to its geometric shape they have high resistance to internal forces and ...
Análise de custos diretos de lajes mistas steel deck e comparativo de custos com lajes pré-moldadas com vigotas treliçadas
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2016-06-22)
This study brings information about the steel deck composite slab and a cost comparative with pre-cast slabs with trussed joists. Starting from the history of steel deck, vantages and disadvantages, an analysis of the ...
Computational modeling of high performance steel fiber reinforced concrete using a micromorphic approach
(Springer, 2013-01)
A finite element methodology for simulating the failure of high performance fiber reinforced concrete composites (HPFRC),with arbitrarily oriented short fibers, is presented. The composite material model is based on a ...
