Structural health monitoring in incrementally launched steel bridges: patch loading phenomena modeling
(2015-10)
Article.
Accés obert
Article.
Accés obert
In this paper, a realistic nonlinear 3D simulation of an incrementally launched steel bridge girder is presented. The numerical simulation accounts for three sources of nonlinearity: geometry, material and boundary conditions. ...

This paper details the research work carried out on masonry mortars produced employing recycled aggregates in 100% substitution for natural sand aggregates. The main objective of the work being the validation of the resulting ...
Effect of fine ceramic recycled aggregate (RA) and mixed fine RA on hardened propertiesof concrete
(2015-06)
Article.
Accés obert
Article.
Accés obert
The ceramic industry is well known for producing large amounts of rejected ceramic waste. During the construction and demolition waste crushing process, a large amount of fine recycled aggregates (FRA) are usually produced. ...
Description of stress-strain curves for stainless steel alloys
(2015-12-15)
Article.
Accés obert
Article.
Accés obert
There is a wide variety of stainless steel alloys, but all are characterized by a rounded stress-strain response with no sharply defined yield point. This behaviour can be represented analytically by different material ...

Article.
Accés obert
Article.
Accés obert
This paper presents a finite element model for the analysis of composite beams with partial interaction. In this model, the elements of the composite beams are modeled by six different types of frame elements. Compared ...
Numerical modelling with experimental validation applied to the study of stud connectors behaviour in concrete and steel composite structures
(Pontificia Universidad Católica de Chile, 2015-04)
Article.
Accés obert
Article.
Accés obert
In this work, the behaviour of stud shear connectors in composite structures is studied, starting from the via numeric simulation of the push out test in a steel beam – with solid concrete slab concrete section is studied. ...
Experimental study on ferritic stainless steel RHS and SHS beam-columns
(2015-12-17)
Article.
Accés obert
Article.
Accés obert
Ferritic stainless steels, with their lower nickel content, supplement the desirable features offered by different stainless steel grades with a more controlled and lower initial investment requirements, which have encouraged ...
Analytical micro-modeling of masonry periodic unit cells : elastic properties
(2015-09-01)
Article.
Accés obert
Article.
Accés obert
A model for the analysis of masonry periodic unit cells based on detailed micro-modeling principles is presented: an analytical model capable of calculating the orthotropic elastic properties of masonry composites. Several ...
Seismic behavior of medium and high strength concrete buildings
(2015-05)
Article.
Accés obert
Article.
Accés obert
Current concrete technology has made higher concrete grades more affordable to mid and high-rise buildings; hence its use has been increasing in the late years as it allows for smaller cross-sections, reduction of the ...
Application of particle motion technique to structural modal identification of heritage buildings
(2015)
Article.
Accés obert
Article.
Accés obert
Determining the behavior of a structure estimated by means of finite elements analysis requires not only an in-depth knowledge of its geometry and dynamic properties but also an experimental validation to corroborate the ...
