Evaluation of Structural Intervention in the Quartel das Esquadras,Almeida (Portugal)

ABSTRACT

The “Quartel das Esquadras” is an 18th century infantry barrack located within the limits of the bulwarked fortress of Almeida, in Portugal. An ongoing adaptive reuse project of the building aims to recover its full capacity and also its importance, by implementing a variety of new uses. The architectural intervention results in the need of the structure to withstand new and diverse imposed loads. As the current configuration of the structure will be altered, the main objective of this article is to evaluate the suitability of some of the proposed structural interventions. The current condition has been characterized following a multidisciplinary approach comprising historical research, visual inspection, non-destructive testing, and structural analysis to identify the possible sources of major structural problems. A portion of the building particularly affected by the alterations has been selected to carry out structural analysis. A comparative safety assessment of the selected area in both current and altered condition has been done through finite element modelling and nonlinear static analysis, resulting in an identification of the weaker points against the new implemented loads and alterations. Finally, proposals for the implementation of the studied intervention, as well as recommendations for future research and analyses, have been given.     

Characterization of concrete from Roman buildings for public spectacles in <Emphasis Type="Italic">Emerita Augusta</Emphasis> (Mérida,Spain)

The aim of this work is to characterize the original concrete from Roman buildings for public spectacles, theatre and amphitheatre, from Emerita Augusta, Mérida, Spain. An advanced knowledge of the Roman concrete composition is required for a reliable restoration and preservation of these ancient monuments. The concrete was studied through mineralogical (optical polarized microscopy and X-ray diffraction) and petrophysical (bulk and real density, open porosity to water and Hg, mechanical strength and ultrasonic velocity) analyses. With this work, it is possible to fill the gap that exists in this field and the characterization of the materials used in the Roman concrete from these two buildings, never previously studied, despite the significance of this archaeological ensemble, declared a World Heritage Site by UNESCO in 1993. The results allowed us to determine the composition of the Roman concrete and to infer the provenance of the aggregates used in these monuments.

“Inhabitants of rustic parts of the world”: John Locke’s collection of drawings and the Dutch Empire in ethnographic types

This article analyses a collection of 26 watercolour drawings which portray ethnographic types from the Americas, Asia, and Africa. These drawings, presently kept at the British Library, were made for John Locke by his servant Sylvester Brounower during Locke’s exile in the Netherlands in the 1680s.     

European Union Competition Policy and the European Territorial Cohesion Agenda: An Impossible Reconciliation? State Aid Rules and Public Service Liberalization through the European Spatial Planning Lens

The territorial and spatial planning impacts of European Union (EU) economic and competition policies have remained under-researched in the field of European spatial planning, in contrast to other EU policy fields. This briefing explores how two elements of the EU competition policy, the regulation of “state aid” and the liberalization of “services of general interest (SGI)”, have significant implications for the pursuit of the objective of territorial cohesion through spatial planning and territorial development policies at different scales. The paper first reviews the development of the concept of territorial cohesion in the EU discourse and policy agenda since the mid-1990s, as well as the contribution of public services (Services of General Interest, or SGI in EU jargon) to it. It, then, reviews how the EU state aid rules and liberalization policies affect the state's ability to intervene (i) in support of sub-national territories which are lagging behind or suffering decline, and (ii) in the provision of public services across the national territory, specifically in peripheral regions or areas where the provision is not catered for by the market. The conclusion of the paper outlines the additional challenges to the pursuit of territorial cohesion in the EU posed by the post-2008 economic crisis and suggests avenues for future research.
