Wind tunnel test of the fifth Tower (Madrid).
The study of site-wind interferences on buildings is an amazing subject. This work is currently carried out by Olaya Gómez Carril. We are comparing the experimental results with the Spanish code. Some CFD models will be also developed.
Alconétar Arches wind tunnel test.
This has become a classical issue in Wind Engineering. Our students will be able to distinguish between many aeroelastic phenomena as well as they learn the types of wind tunnel test: sectional 2D and complete 3D. This work is currently conducted by Anselmo Antuña Gómez. A 2D CFD model is being analyzing.
Aerodynamic study of box & struts deck bridge.
This experiment explains the behaviour of a launched bridge and the influence of the struts and upper slab on the aerodynamic coefficients. This work is currently conducted by Javier Ruiz Berciano.
Influence of scaffolding supports on the aerodynamics of a bridge formwork.
There is no structured and systematised information about aerodynamic coefficients on bridge scaffoldings and formworks. This work is currently conducted by Marcelo Álvarez Gallego and bridge the gap between the codes and reality.
Aerodynamic study of the four towers of Madrid.
Another interesting project: study of site-wind interferences on buildings. Some time ago we have studied the case of the 4 towers of Madrid. We expect to apply all that knowledge to the construction of the fifth!!! The work has been developed by Ignacio Rodríguez Sánchez. This study is being complemented with a numerical simulation (CFD).

In the present Bach. Thesis, the aerodynamic study of a wooden footbridge designed by Media Madera Ingenieros Consultores S.L. is carried out. The work has been developed by Efrén Gómez García. For this purpose, the static wind loads on the structure obtained by means of experimental tests in wind tunnels are compared with the results determined by applying the calculation rules of the "Instrucción sobre las acciones a considerar en el proyecto de puentes de carretera (IAP-11)", which is the regulation that governs the determination of bridge loads in Spain.

To perform the experimental tests, a reduced scale model manufactured by ATG is used. This model is identical to the footbridge under study and reproduces all the details and magnitudes at 1/20 scale of the real bridge that are relevant from the aerodynamic point of view.
Therefore, the main objectives that will be developed throughout the document are the following
- Calculation of the aerodynamic force on the model at a reduced scale, resulting from the composition of a horizontal or drag force and a vertical or lift force, and applied in a given line of action.
- Determination of the frequency of vortex shedding.
- Dimensioning of the phenomenon, through aerodynamic force coefficients.
- Calculation of the aerodynamic force on the catwalk prototype, both from the experimental results and from the application of the IAP-11 standard.
- Preliminary design of a numerical simulation for the calculation of the forces and aerodynamic coefficients.
- Comparison of the results of the three studies: experimental tests in wind tunnels, application of the current regulations and calculation by the finite volume method.
Although it is not the main objective of the project, a preliminary 2D numerical simulation by finite volume method (Computational Fluid Dynamics, CFD) of the structure is also carried out, whose results will be compared with those obtained following the current regulations and the experimental tests in the wind tunnel.

The aim of this Bach. Thesis by Ignacio Romero Villanueva is to study the aerodynamic behaviour of a self-launching formwork (MSS) used for the construction of road bridges. Specifically, the behaviour of the main beam, that is, without the part of the machine that performs the formwork functions. It is a reality that the improvement of the mechanical properties of the materials traditionally used in the building industry, the adoption of new construction techniques as well as the incorporation of new materials, allows buildings to be more audacious every day, with shapes that are little or not at all similar to the basic shapes used in traditional architecture.

For this reason there are more and more buildings in which wind loads (static and dynamic) play a very important role. Thus, wind, a factor hardly taken into account in traditional construction, has become a determining factor when evaluating design loads on quite a number of current buildings.
The need for this study arises because of the unique character of the structure, with shapes and characteristics far removed from those included in wind design standards and for which it is difficult to reliably estimate aerodynamic loads by analytical methods. For this reason, it is increasingly common to resort to scale model tests in wind tunnels.
The aerodynamic study is carried out by two methods:
- Experimental tests in the EB40-oWT wind tunnel, belonging to the Department of Energy of the University of Oviedo, of a 1/36 scale model of the upper beam of the self-launching formwork and manufactured with a 3D printer in lactic polyacid (PLA).
- Analytical study of the action of the wind applying the current regulations (IAP-11).
