The Basilica of San Francesco in Assisi endured stronger earthquakes for centuries before 1997 earthquake, which generated the collapse of the two vaults. Experts blame as possible reasons of collapse the damage cumulated from previous earthquakes and/or the retrofitting made to the structure over its lifetime. This article presents the history of the retrofit interventions of the Basilica through the centuries, focusing mainly on the roof, which has been subjected to three major restorations through its life. It is shown using simple analytical models that the cumulative effects of the changes made to the roof of the Basilica affected the structure’s dynamic behavior in a negative manner, increasing the seismic loads on the existing structural members. In particular, the numerical results show that the 1958 roof intervention has stiffened the structure, redistributing the seismic loads on the façade and the transept. This overload might explain the collapse of the two Gothic vaults during 1997 earthquake. 相似文献

A framework for quick seismic assessment and retrofit of traditional unreinforced masonry (URM) structures is presented. The proposed methods build on simple principles of structural dynamics and are used as an alternative to detailed time-history analysis, in recognition of the prevailing need for simple and practical methods, compatible with the low-budget and the limited level of knowledge regarding materials, internal force paths, connectivity and condition of older URM structures. An objective is to identify areas in the building that are particularly susceptible to damage and for guiding the types of the required global interventions to improve seismic response. Demand and supply are expressed in terms of relative drift ratios that quantify the intensity of out-of-plane differential translation and in-plane shear distortion of masonry walls. A characteristic traditional building type of timber-laced masonry is used as a model structure for illustration of concepts. The morphology and geometry of the building correspond to a statistical sample of the actual traditional unreinforced masonry buildings (TURM) found in historical centers of many towns in the greater region of Northern Greece. The methodology is particularly useful for setting retrofit priorities and management of the collective seismic risk of historical entities. 相似文献

While power asymmetry typically defines security relationships between allies, there exist other forms of asymmetry that influence alliance politics. In order to illustrate how they can shape policy outcomes that cannot be explained solely through the lens of power capabilities, the authors examine the role of relative attention that each side pays to the alliance. It is their central argument that since the client state has a greater vested interest in the alliance and given that attention depends on interest/need, the client state can leverage attention to get its way. By analysing two specific cases, the 2002 South Korean schoolgirls tragedy and the 2008 beef protests—instances where the South Koreans succeeded in compelling US concessions—the authors show that because the alliance was more central to the client state's agendas, there existed an asymmetry of attention that offered leveraging opportunities for the weaker ally. In this study, the authors emphasise the role of media attention as a key variable, and seek to contribute to debates on weaker party leverage in asymmetrical alliances. 相似文献

Satellite radio posed a new question for Canadian policy-makers: How to take advantage of a transnational radio service while ensuring cultural identity was not lost within channel offerings that are predominately American. Comparing the initial licensing of satellite radio in Canada (2005) to the merger of the services (2011) and the post-merger license renewal (2012) highlights a shift in the spatial understanding of satellite radio, from being determined by a satellite’s footprint to that of what I call ‘cultural lifelines,’ the various mobile devices and services that enable one to maintain connection to cultural content. Alongside shifting spatial considerations of satellite radio, Canadian content has increasingly been packaged as a brand or genre, catering to fragmented taste preferences and individual, mobile listening practices. 相似文献

The promotion of the German language abroad and of German Studies plays a central role in German Foreign Cultural Policy. With regard to Sub-Saharan Africa, otherwise a peripheral region for foreign policy, German as foreign language is firmly established as second language after English. Learners especially in Francophone West and Central Africa have increased over the past decade. Numerous funding programmes and actions are supported by German nongovernmental organizations at college/university levels. But bilateral cooperation between German and African academic institutions are challenged both by negative perceptions of the ‘Global South’ among Western colleagues and by an infrastructure adverse to research and to career development in most African countries. Additionally, North/South relations are traditionally seen in terms of (under-)development by German institutions, effecting cooperation. The paper develops a differentiated picture of African Studies in Africa, and outlines benefits that can be attained through collaboration ‘at eye-level’. 相似文献

Although the factual chronology of World War II is not in dispute, how to best make sense of these facts and how to objectively evaluate that history have always been limited by political circumstances and personal biases. Viewing WWII seven decades later, we need to move away from Eurocentrism and to stop seeing the war from the prism of a European war or Pacific war. The entire history of WWII, from beginning to end, including its several phases characterized by fermentation, outbreak, climax, and conclusion, is extremely complex. This paper argues that the war has two origins or starting points because it resulted from disparate prewar conditions in Europe and Asia. Viewed from this perspective, the strategic importance of the China Theater in WWII and the enormous sacrifices and contributions the Chinese people made to the victory over Fascism and for world peace ought to be given due credit. 相似文献

与历代诸多代人受刑的案件相比,清代命案中的顶凶案件有其自身的特点。顶凶案发生的原因和情节错综复杂,成为一种危害深重的畸形社会现象。发生时间表现为乾隆以降,数量逐渐增多;发生区域以福建、广东地区的械斗顶凶案件最为典型;立法过程表现为例文与司法的相互调适并趋向宽纵。从一手史料出发,对顶凶案件背后的生成机制和司法实践进行探寻和考证,可以在一定程度上揭示清代社会民众的政治生态、文化心理和价值取向,透视出官方与民间的互动实态。 相似文献

土楼是福建西南部以永定为中心的客家人的民居。这种民居非常特殊,有方形、园形。多为四层,中间为庭院。居民多属同族、同宗、同姓。它是北方因战乱而南迁的移民带来的。在东汉以后。北方战乱,大姓士绅多聚居建成坞壁,作为保护自己。客家人南迁到福建西南,在少数民族与荒野之中,也采取这种形式建筑以适应防守需要。永居的土楼在当地环境亦有发展,特别是园形土楼,形成独特形式。由于客家人聚族迁移此地,土楼既适应其特殊环境,而且也进一步促进了客家人以耕读为中心的强大内聚力的文化的发展。因此,土楼既是客家文化的一种外在景观,又是其文化内涵的外在条件。 相似文献
