Brexit: initial reflections

Even though the opinion polling before the British referendum on membership of the European Union showed a narrow gap between the two sides, the actual result—a vote to leave—on the morning of 24 June 2016 came as a surprise to many. Yet in truth both the referendum and its outcome had deep roots in British politics. In this article we cast an eye over the history of Britain's relationship with the EU, which has long been marked by a mixture of awkwardness and successful influence. We trace the origins of the referendum in long‐run tensions between, and within, the political parties, and in the lukewarm public support for European integration. We also examine more contingent, short‐term factors relating to the referendum campaign itself. We conclude by commenting on the divisions exposed by the vote along lines of geography, education, class and wealth, and suggest that reconciling these with the continuing tensions in the party landscape make a clean and speedy exit from the EU unlikely.     

A RETRIEVAL OF HISTORICISM: FRANK ANKERSMIT'S PHILOSOPHY OF HISTORY AND POLITICS

Frank Ankersmit is often perceived as a postmodern thinker, as a European Hayden White, or as an author whose work in political philosophy can safely be ignored by those interested only in his philosophy of history. Although none of these perceptions is entirely wrong, they are of little help in understanding the nature of Ankersmit's work and the sources on which it draws. Specifically, they do not elucidate the extent to which Ankersmit raises questions different from White's, finds himself inspired by continental European traditions, responds to specifically Dutch concerns, and is as active as a public intellectual as he has been prolific in philosophy of history. In order to propose a more comprehensive and balanced interpretation of Ankersmit's work, this article offers a contextual reading based largely on Dutch‐language sources, some of which are unknown even in the Netherlands. The thesis advanced is that Ankersmit draws consistently on nineteenth‐century German historicism as interpreted by Friedrich Meinecke and advocated by his Groningen teacher, Ernst Kossmann. Without forcing each and every element of Ankersmit's oeuvre into a historicist mold, the article demonstrates that some of its most salient aspects can profitably be read as attempts at translating and modifying historicist key notions into late twentieth‐century categories. Also, without creating a father myth of the sort that White helped create around his teacher William Bossenbrook, the article argues that Ankersmit at crucial moments in his intellectual trajectory draws on texts and authors central to Kossmann's research interests.     

ON THE OPTIMAL LOCATION OF SENSORS IN MULTI-STOREYED BUILDINGS

A new approach has been developed for finding optimal location of sensors in 3D multi-storeyed buildings. This approach is based on the compact probabilistic representation of acceleration response in terms of its covariance matrix. For a specified number of sensors, the optimal location has been taken to be the one for which the computed covariance matrix is closest to the exact covariance matrix of the random field constituted by the acceleration response process. It has been found that the determined sensor locations match favourably with those predicted by earlier studies for the special case of shear buildings. Further, the optimality of the determined sensor locations has also been verified by identifying the system parameters from the time series data and comparing them with those of the Finite Element Model.     

SEISMIC REHABILITATION OF BEAM-COLUMN JOINTS USING FRP LAMINATES

An innovative and practical technique for the seismic rehabilitation of beam-column joints using fiber reinforced polymers (FRP) is presented. The procedure is to upgrade the shear capacity of the joint and thus allow the ductile ftexural hinge to form in the beam. An experimental study is conducted in order to evaluate the performance of a full-scale reinforced concrete external beam-column joint from a moment resisting frame designed to earlier code then repaired using the proposed technique. The beam-column joint is tested under cyclic loading applied at the free end of the beam and axial column load. The suggested repair procedure was applied to the tested specimen. The composite laminate system proved to be effective in upgrading the shear capacity of the nonductile beam-column joint. Comparison between the behaviour of the specimen before and after the repair is presented. A design methodology for fibre jacketing to upgrade the shear capacity of existing beam-column joints in reinforced concrete moment resisting frames is proposed.
