Comparative study of trusses to determine the influence of the geometry in the structural efficiency, according to the directions of the principal stresses : Part II
(Víctor Compán Cardiel [etc.], 2015)
This study compares flat lattice girders mounted on two supports, based on various design parameters, to determine which have better structural performance and what geometries are more efficient. The fundamental goal is ...

Towards a unified mechanical model for design and assessment of structural concrete members under shear, flexure and punching
(Víctor Compán Cardiel [etc.], 2015)
A mechanical shear model for structural concrete members with and without stirrups is presented, which incorporates the most relevant shear transfer mechanisms. The model is based on the principles of structural mechanics, ...

Optimización de una cimentación pilotada y de la superestructura de un centro comercial mediante simulación de la interacción terreno-estructura en suelos licuefactables con un caso de sismo dimensionante : análisis comparativo de los resultados con y sin interacción terreno estructura
(Víctor Compán Cardiel [etc.], 2015)
Soil-structure interaction techniques have been widely written about and largely used in the Energy domain, even if they are still not commonly used among Civil Engineers. Nevertheless, these techniques have been introduced ...

Modelling crack growth in quasi-brittle materials using mesh fragmentation technique
(Víctor Compán Cardiel [etc.], 2015)
The modelling of discontinuities with new finite element techniques (X-FEM and E-FEM) is cumbersome due to the need of algorithm tracking to simulate the crack growth. Therefore, a new technique to capture strong discontinuities ...

Automatic counterfort retaining wall desing by simulated annealing and extreme value estimation
(Víctor Compán Cardiel [etc.], 2015)
This paper focusses on the automatic design and cost minimization of reinforced concrete buttress earth-retaining walls using a Simulated Annealing (SA) algorithm and the Extreme Value Theory (EVT). The study involves a ...

Dynamic characterization, modelling and model updating of a lively footbridge
(Víctor Compán Cardiel [etc.], 2015)
This paper presents finite element analyses, experimental measurements and finite element model updating of a lively footbridge consisting on an arched main span 40m long and several shorter access spans. Firstly, a finite ...

Dynamic behavior of masonry chimney with different reinforcement schemes
(Víctor Compán Cardiel [etc.], 2015)
This paper presents a structural analysis of a masonry chimney built in the 1950’s, which is currently being catalogued as local interest heritage. These structures exhibit insufficient tensile strength to resist the seismic ...

Self-control of a lively footbridge under pedestrian flow
(Víctor Compán Cardiel [etc.], 2015)
In this paper, a case study about a lively footbridge is developed; the vibration levels caused by the pedestrian action are controlled by the change of the modal parameters of the structure due to the pedestrian-structure ...

On the insurmountable size of truss-like structures
(Víctor Compán Cardiel [etc.], 2015)
Galileo postulated the existence of an insurmountable size for stone columns bearing a useful load as the size for which the structure is only able to resist its self-weight. Herein a method for the determination of the ...

Replacement of cables of the cover archs carbon park in As Pontes (A Coruña)
(Víctor Compán Cardiel [etc.], 2015)
The work done by Acciona Engineering at the coal yard located in As Pontes, is included within the maintenance plan established by Endesa for the period 2010-2020. This consists of predictive, preventive and corrective ...
