What a maritime history! The uses of maritime history in summer festivals in southern Norway
2009
This is a preprint of an article whose final and definitive form has been published in the Journal of Tourism History 2009 copyright Taylor & Francis. Article available at InformaWorld: http://dx.doi.org/10.1080/17551820902823259 This paper focuses on the growth of cultural heritage tourism in southern Norway, with a particular focus on maritime history presented at summer festivals during recent years. I will be using newly collected empirical data gathered from two festivals: Kjæmpestaden (Giant Town) in Arendal and Kapernatten (Privateer Night) in Farsund. In 2006 and 2007, both festivals included grand outdoor plays based on the history of the Napoleonic Wars (1807–1814). Since Tordensk…
Solutions for the Design and Increasing of Efficiency of Viscous Dampers
2016
In last decades many strategies for seismic vulnerability mitigation of structures have been studied and experimented; in particular energy dissipation by external devices assumes a great importance for the relative simplicity and efficacy. Among all possible approaches the use of fluid viscous dampers are very interesting, because of their velocity-dependent behaviour and relatively low costs. Application on buildings requires a specific study under seismic excitation and a particular attention on structural details. Nevertheless seismic codes give only general information and in most case the design of a such protection systems results difficult; this problem is relevant also in Italy whe…
Sharing Mare Nostrum: An Analysis of Mediterranean Maritime History Articles in English-Language Journals.
2015
This discussion paper is a follow-up to a previous bibliometric analysis of articles published in The International Journal of Maritime History and maritime-themed articles published in other economic and business history journals over the last 25 years. The paper looks more closely at articles dealing with the Mediterranean and articles written by scholars from the Mediterranean countries. The article is structured around five propositions about current trends in Mediterranean maritime history publishing in English-language journals.
Dissipative connections of rc frames with prefabricated steel-trussed-concrete beams
2020
In the last thirty years, Hybrid Steel-Trussed Concrete Beams (HSTCBs) have been widely used in civil and industrial constructions and, therefore, their mechanical performance must be evaluated with the aim of guaranteeing adequate dissipation of the seismic energy particularly in the beam-to-column joints. However, one of the most frequent peculiarities of HSTCBs is that of using their own steel joist to cover large spans with reduced depth and, in the case of traditional beam-to-column connections, this requires large amount of steel reinforcement inside the panel zone, often made with large diameter rebars. These characteristics make both the panel zone and the beam end potentially vulne…
Remarks on the History of the Navy of the Empire of Nicaea in the Light of the Chronicle of Georgios Akropolites
2016
The Empire of Nicaea was a successor of the Byzantium shattered in 1204. In the newly established state marine traditions of Byzantines, remain alive. The best testimony to this, are the evidence contained in the chronicle of Georgios Akropolites, devoted to activities of the rulers of Nicaea, aimed to build their own naval forces. In this paper I'll also try to answer, where was beating the heart of the Nicean shipbuilding industry and how large was the navy of this state. This is important from point of view of the maritime history, because of the fleet of the Empire of Nicaea, filled the gap created after the fall of Constantinople and the Byzantine Empire, which was the local naval powe…
Response spectrum analysis of frame structures: reliability-based comparison between complete quadratic combination and damping-adjusted combination
2019
In the framework of seismic design of structures, response spectrum analysis (RSA) is the most commonly used approach in practice. The most popular combination rule is the complete quadratic combination (CQC) which is also prescribed by the most of seismic design codes and is based on the assumptions that the seismic acceleration is a white noise process and the peak factor ratios associated to the total and modal responses are unitary. Recently, the damping adjusted combination (DAC) rule has been developed for base-isolated structures to overcome the aforementioned simplified assumptions. Although it has been proved that the simplifications about peak factors lead to noticeable errors in …
Incremental dynamic based fragility assessment of reinforced concrete structures: Stationary vs. non-stationary artificial ground motions
2017
Abstract Artificial and natural records are commonly employed by researches and practitioners to perform refined seismic assessments of structures. The techniques for the generation of artificial records and their effectiveness in producing signals which are significantly representative of real earthquakes are still debated as well as results of the consequent seismic assessment to expect from their application. The paper presents an in-depth comparative study highlighting the effect of employing different typologies of artificial ground motion records on seismic assessment results, especially addressing seismic fragility curves. Three sets of 50 stationary, nonstationary evenly modulated a…
Influence of wall-to-floor connections and pounding on pre- and post-diction simulations of a masonry building aggregate tested on a shaking table
2023
AbstractThis paper presents numerical simulations within the frame of the project SERA—AIMS (Seismic Testing of Adjacent Interacting Masonry Structures). The study includes blind pre-diction and post-diction stages. The former was developed before performing the shaking table tests at the laboratory facilities of LNEC (Lisbon), while the latter was carried out once the test results were known. For both, three-dimensional finite element models were prepared following a macro-modelling approach. The structure consisted of a half-scaled masonry aggregate composed by two units with different floor levels. Material properties used for the pre-diction model were based on preliminary tests previou…
Deskilling and decline in skill premium during the age of sail : Swedish and Finnish seamen, 1751–1913
2016
The study examines the evolution of skill premium and share at industry level in shipping during the age of sail. We argue that the period from the 1750s to the 1910s represented deskilling for the seamen working in sailing ships. The growth of international trade and shipping during the first era of globalization increased the overall demand for sailors but decreased the relative demand for skilled labor in favor of less skilled ones. This deskilling was associated with a decline in wage inequality, as the premium for high skilled seamen fell relative to mean wages in the shipping industry. The decline in skill premium may have facilitated the growth of trade and shipping, as the relative …
Scansar le frodi. Prede corsare nella Sicilia del decennio inglese (1808-1813)
2013
This essay discusses the topic of fraud linked to the prizes taken by corsairs in the Mediterranean during the period of the Continental Blockade, from the viewpoint of the Kingdom of Sicily, where the Bourbon court was sheltering under the English protectorate. The Tribunale delle prede (1808-1813) judged the legitimacy of the prizes taken by armed Sicilian corsair vessels from ships flying enemy or neutral flags, in a complex juridical framework which also involved the Health and Police authorities, at a time when in the rest of Europe similar institutions were being created. The documents produced by the Tribunale offer a penetrating insight into the dynamics of the fraud and into the pr…
