Linearly elastic seismic evaluation of masonry historical buildings in Santiago, Chile : The case of the Pereira Palace
(Víctor Compán Cardiel [etc.], 2015)
Seismic assessment of the Pereira Palace by means of linear elastic analysis using finite elements techniques is the purpose of this work. Three static analysis based on the provisions of the current Chilean seismic code ...

A procedure to track vibration modes under changing external factors : application to a pedestrian bridge
(Víctor Compán Cardiel [etc.], 2015)
A low-cost vibration monitoring system has been developed and installed on an urban steel- plated stress-ribbon footbridge. The system continuously measures: the acceleration (using 18 triaxial MEMS accelerometers distributed ...

Experimental validation of usual numerical models of cracked beams for damage detection approaches
(Víctor Compán Cardiel [etc.], 2015)
The performances of damage detection approaches are often tested by using numerical solutions of undamaged and damaged structures. However, the numerical results used for a preliminary analysis are useful as far as they ...

Mechanical characterization of sportive tracks made with materials recycled from end-of-life tyres
(Víctor Compán Cardiel [etc.], 2015)
The European Framework Directive 2008/98/EC on waste established as priority reuse and recycling before other recovery alternatives. In this normative reference, one the main waste flows identified are the end-of-life ...

A postgraduate course on precast-prestressed concrete road bridges optimization
(Víctor Compán Cardiel [etc.], 2015)
This paper deals with a postgraduate course in project engineering that forms part of an MSc course in Concrete Engineering at the Universitat Politècnica de València. The course is concerned first with the basic heuristic ...

Serviceability conditions of pedestrian structures using a simplified moving mass model
(Víctor Compán Cardiel [etc.], 2015)
A simple mechanical model for pedestrian loading, consisting on a mass with a single degree of freedom that moves at constant speed along the footbridge, is presented. The footbrigde is modelled using a reduced number ...

Damage assessment in a reinforced concrete pedestal based on rotating machinery vibration analysis
(Víctor Compán Cardiel [etc.], 2015)
A critical operational condition to be considered in the fatigue damage evaluation in reinforced concrete pedestals of power plants generation is the caused by the dynamic effects transmitted by the turbo-generator in terms ...

Estimating robust optimum parameters of tuned mass dampers using multiobjective genetic algorithms
(Víctor Compán Cardiel [etc.], 2015)
Tuned mass dampers (TMD) are a well-known control device widely used to control the vibratory problem originated by the pedestrian action on footbridges. The main purpose of this study is the robust multi-objective ...

Modelling of the behavior of post-tensioned concrete structures subjected to long term thermal loads
(Víctor Compán Cardiel [etc.], 2015)
The effect of the reduction of concrete material strength and the deformations and stress level due to the non-uniform temperature distribution within a structural element such as a storage tank has a coupled negative ...

Reliability-based optimization of steel structures using genetic algorithms and nonlinear finite elements
(Víctor Compán Cardiel [etc.], 2015)
Uncertainties are inherent in material properties, geometry parameters and loading in structural design problems. In a realistic design, it is necessary to consider these types of uncertainties to ensure safety and quality. ...
