Indirect georeferencing of terrestrial laser scanning data using control lines
(2013-09-01)
An indirect method for the georeferencing of 3D point clouds obtained with terrestrial laser scanning (TLS) data using control lines is presented. This technique could be used for rapid data acquisition where resources do ...
Investigação numérica sobre a detecção de danos em vigas metálicas pelo método do erro na equação de movimento
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2017-11-30)
The main objective of this paper was to develop a numerical investigation regarding the application of Error Method in the Motion Equation in beams. The method tested was developed by Genovese (2000) and basically consists ...
Estrategias de rigidización para vigas esbeltas con perforaciones sujetas a cargas cortantes
(Departamento de Ingeniería CivilUniversidad Nacional de Colombia - Sede Medellín, 2019-11-30)
During the construction of bridges by successive overhangs the main beams of the bridge are subjected to shear loads, as a result a buckling failure can occur. Occasionally the girders must be perforated to allow the passage ...
Automatização do cálculo de ligações parafusadas: ligação viga-pilar rígida com chapa de topo e ligação viga-viga flexível com dupla cantoneira
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2016-11-28)
A connection in a structure is responsible for the union and transmission of forces or moments from one structural element to another, such as beams and columns. The aim of this work is to study bolted connections in metal ...
Análise numérica e experimental de uma viga sujeita a cargas dinâmicas
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia MecânicaUTFPR, 2017-06-09)
The purpouse of this work is to perform a study involving the finite element method and image processing in a beam subjected to dynamic loads. The beam was set at one end and free at the other, where an impulsive force was ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
Análise e dimensionamento de uma viga de ponte ferrovíaria em concreto protendido
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2015-02-25)
This paper has as its main goal to design and analyze a railway bridge stringer in prestressed concrete. This kind of structure, called special art of work, is very important to railway. In order to determine the ideal ...
Estudo experimental sobre o uso de estribos de plástico como armadura transversal em vigas de concreto armado
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2018-06-19)
In a competitive market, the search for new materials aiming at a greater productivity with reduction of costs entails the creation of new products with unknown properties or without technical specifications. As for the ...
Análise comparativa experimental e numérica de uma viga engastada livre flexionada em regime não linear
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia MecânicaUTFPR, 2017)
The present work has the objective of comparing the displacements of a beam subjected to bending, using different measurement methods. For the measurement of displacement, three tools were used, the traditional measurement ...
