Imposed Deformations Measured on a Real Integral Structure: New Airport Terminal Barajas, Madrid, Spain

Experimental research on imposed deformation is generally conducted on small scale laboratory experiments. The attractiveness of field research lies in the possibility to compare results obtained from full scale structures to theoretical prediction. Unfortunately, measurements obtained from real structures are rarely described in literature. The structural response of integral edifices depends significantly on stiffness changes and constraints. The New Airport Terminal Barajas in Madrid, Spain provides with large integral modules, partially post?tensioned concrete frames, cast monolithically over three floor levels and an overall length of approx. 80 m. The field campaign described in this article explains the instrumentation of one of these frames focusing on the influence of imposed deformations such as creep, shrinkage and temperature. The applied monitoring equipment included embedded strain gages, thermocouples, DEMEC measurements and simple displacement measurements. Data was collected throughout construction and during two years of service. A complete data range of five years is presented and analysed. The results are compared with a simple approach to predict the long?term shortening of this concrete structure. Both analytical and experimental results are discussed.

Application of Public Private Partnerships to the Spanish Airport System

The current deficit situation of the Spanish airport system suggests the need to manage this in a more efficient and profitable way. One of the possible options is through private management and being able to do this through Public Private Partnerships (PPP). This study analyzes the situation of the sector and its economic importance and the different possibilities for introducing private management in a public company, specifying the situation in the case of airports, presenting the advantages and disadvantages of these possibilities, and aiming at results obtained in other places where it has been applied. It is proposed that the ideal model for the introduction of private management would be through PPP models tailored to each airport, but having common characteristics according to the group they belong to. Finally, we observe that not all airports are commercially attractive, so that the PPP concept does not apply to all of them. In some cases even the operability itself is not viable at all, and that should be considered separately in order to avoid creating a private monopoly while trying to enhance competition among them.

Tenerife South Airport (Phase III)

An architecture of light and shadows is proposed for this airport for the twenty-first century. A great concrete and stone box to frame the incredible view south towards a red mountain that rests Sphinx-like over the Atlantic. = Se propone para este aeropuerto para el siglo XXI una arquitectura construída con la luz y con las sombras. Una gran caja de hormigón que enmarca un maravilloso paisaje: el océano atlántico al sur con la montaña roja que se acuesta sobre el mar como si de una esfinge se tratara.

Territorial cohesion impacts of high-speed rail under different zoning systems

Large-scale transport infrastructure projects such as high-speed rail (HSR) produce significant effects on the spatial distribution of accessibility. These effects, commonly known as territorial cohesion effects, are receiving increasing attention in the research literature. However, there is little empirical research into the sensitivity of these cohesion results to methodological issues such as the definition of the limits of the study area or the zoning system. In a previous paper (Ortega et al., 2012), we investigated the influence of scale issues, comparing the cohesion results obtained at four different planning levels. This paper makes an additional contribution to our research with the investigation of the influence of zoning issues. We analyze the extent to which changes in the size of the units of analysis influence the measurement of spatial inequalities. The methodology is tested by application to the Galician (north-western) HSR corridor, with a length of nearly 670 km, included in the Spanish PEIT (Strategic Transport and Infrastructure Plan) 2005-2020. We calculated the accessibility indicators for the Galician HSR corridor and assessed their corresponding territorial distribution. We used five alternative zoning systems depending on the method of data representation used (vector or raster), and the level of detail (cartographic accuracy or cell size). Our results suggest that the choice between a vector-based and raster-based system has important implications. The vector system produces a higher mean accessibility value and a more polarized accessibility distribution than raster systems. The increased pixel size of raster-based systems tends to give rise to higher mean accessibility values and a more balanced accessibility distribution. Our findings strongly encourage spatial analysts to acknowledge that the results of their analyses may vary widely according to the definition of the units of analysis.

Renewable Energy Systems in the City of Northglenn: Draft Zoning Ordinance and Resident Pamphlet

Recent federal incentives and increased demand for home photovoltaic and small wind electrical systems highlights the need for consistent zoning ordinances and guidance materials for Northglenn residents. This Capstone Project assesses perceived impacts related to renewable energy systems, like noise, safety, aesthetics, and environmental considerations, and provides a model ordinance intended to mitigate these issues. It was concluded a model ordinance would ease and stimulate additions of alternative energy systems in Northglenn. Additionally, this research concluded development of public information could stimulate homeowners into positive decisions. The project also identifies potential financial and environmental benefits of installing such systems in an effort to promote sustainable and clean energy production within the city.
