In the scope of European Cooperation in Science and Technology–Wood Science for Conservation of Cultural Heritage (COST IE0601–WoodCultHer) (available at http://www.woodculther.org) it was agreed to produce Guidelines for the Assessment of Historic Timber Structures, covering the principles and possible approaches for the safety assessment of old timber structures of historical relevance that could be used as the basis for possible European Standards, as discussed with CEN/TC346 (Conservation of Cultural Heritage).
This approach was targeted at all those concerned with the conservation of heritage buildings. These guidelines should also help decision-making regarding the need for immediate safety measures. The aim is to guarantee that inspection and assessment measures provide the necessary data for historical analysis, structural safety assessment, and planning of intervention works, while having minimal impact on the building fabric (the original materials, structural systems, and techniques).This article provides information on the criteria to be used in the assessment of load-bearing timber structures in heritage buildings. It covers the preliminary assessment (desk survey, preliminary visual survey, measured survey, structural analysis, and preliminary report), as well as the detailed survey of timbers (with a special emphasis on visual strength grading on site) and carpentry joints. The subsequent diagnostic report and the detailed design of repairs are outside its scope. 相似文献

Finnish Cold War foreign policy was based on the desire to stay out of all international disputes. Yet, during the 1950s, two Finnish tankers, Wiima and Aruba, received an enormous amount of foreign attention when they tried to sail to Communist China. The United Nations had urged all countries, including non-members such as Finland, to stop selling strategic goods to China, which had intervened in the Korean War. The embargo created a highly profitable opening in the shipping market for anyone willing to transport such goods, and Finnish companies tried to fill it. This article suggests that they were in fact undermining the embargo more extensively than has been generally known. When the Finns were criticized for their actions, they interpreted this as a sign of the ruthlessness of great powers. At first, the Finnish government failed to recognize that these companies drove the country into the middle of international conflict and then took little decisive action to steer the country out of it. The allegedly pragmatic Finnish foreign policy was in this case actually based on unreliable information and incorrect assumptions. 相似文献

Chicago's remarkably flexible growth machine, like their brethren across Rust Belt America, continues to aggressively press forward to build an internationally competitive city. This paper deepens our understanding of Chicago's recently changed growth machine. It focuses on its current redevelopment narrative as it is used on the South Side and chronicles two new features about it: its revamped use of fear and its re-fashioned notion of culture. I flesh out these two elements as they circulate through a now dominant redevelopment program: historic preservation. I chronicle three points in this paper. First, programs like historic preservation, like so many current city programs, have now fully shifted to being a neoliberal economic development tool to promote the “go-global Chicago” project. Second, two dominant fears recently nuanced anchor the narrative: fear of a city-destroying globalization and fear of city-subverting poor African-Americans. Third, a revamped notion of culture is used that helps provide resonance and dark appeal to the two offered fears. The culture notion is put into play as two dominant things, as the idealized and timeless glue that unifies Chicago's mainstream and as problematic values and meanings carried by black bodies which renders them civic tainting “ocular trash”. 相似文献

Since its inception, modern conservation has derived the significance of a heritage asset from the identification and prioritisation of distinct classes of values. Different systems of values have been proposed, and the focus of the debate has been on the competing merits of such systems, with little attention paid to the genealogy of their theoretical foundation. If such values-based systems were ever appropriate, they are increasingly out of step with other areas of cultural life, and the resulting tensions are particularly manifested when considering change to historic buildings and environments. The currently under-theorised state of conservation is positively harmful both to the conservation professions and to the buildings we seek to protect. It is increasingly urgent therefore that we understand conservation’s philosophical origins, that we question the application of a late-nineteenth-century modernist approach to culture, and that we seek a better theoretical foundation. 相似文献

This article analyzes the indoor climate that creates risk of damages in naturally ventilated churches in the cold climate of Estonia. Indoor temperature and humidity were measured over a one-year period and the results were analyzed on the basis of damage functions: mold growth, risk of cracking and fracturing of wooden objects, and delamination of the gesso layer of panel paintings.
In unheated churches, one of the most dominant problems was very high relative humidity throughout the year, creating a high risk for mold and algae growth. Churches may need background heating to avoid freezing during a long cold winter that causes low surface temperatures of massive walls during the spring–summer period. It was found that mold risk was significantly lower in heated churches than in unheated or intermittently heated churches. The risk of mold growth was not decreased by the use of intermittent heating.
In heated churches, overheating (room temperature >+10ºC) causes a RH below 50% during cold periods, and the favorable period for irreversible response of panel paintings was significantly longer, so there is a higher risk that the gesso may crack or delaminate. From the point of view of the cracking and fracturing of wood, indoor climate conditions are in the safe range for most of the year. 相似文献

In 2014 Russia occupied and then annexed the Ukrainian region of Crimea, and subsequently incited and later directly supported a rebellion in southeastern Ukraine, ostensibly in both cases to protect the Russian-speaking population. Although the Crimean gambit was quickly resolved in Russia’s favor, at least on the ground, the fighting in the Donbas region of eastern Ukraine continues with huge loss of life, well over 2 million internally displaced persons, and massive damage to infrastructure. On the other hand, in the neighboring Kharkiv region, the population remained loyal to the Ukrainian state and Russian incitements to rebellion were rebuffed. This paper delves deeper into the mindset of the residents of eastern Ukraine to ascertain why support for Russia differs between these two regions. It focuses on the identities, memories, and narratives of the main groups of residents inhabiting the Donbas and Kharkiv Oblast. Then it compares the attributes of these main groups to each other to illustrate their differences. It characterizes the geopolitical narratives promoted by Russia to generate support for its actions to re-construct the Russian geostrategic area of control and demonstrates where and with which group these emotive narratives were successful and where and why they failed. 相似文献

Past earthquakes have demonstrated that historical vaulted adobe buildings are highly vulnerable to seismic actions. Hence, it is crucial for such building typologies to be evaluated in terms of seismic capacity. To this end, this article deals with the seismic performance of historical vaulted adobe houses from the city of Yazd, Iran as one of the seismically active areas of the world and possessing a very rich adobe heritage. Thus, and based on a detailed geometrical survey, a representative sample of adobe houses from Yazd was studied using a simplified in-plane analysis based on three geometric indexes. Concerning the out-of-plane behavior, a deeper assessment was conducted by performing a numerical study, where the main influential parameters on the seismic behavior of vaulted adobe buildings were considered. The numerical analyses were carried out by adopting the limit analysis theory implemented in the Block2D software. The results obtained indicate the safe in-plane behavior of most of the houses and the safe out-of-plane response of the sample under gravitational loads. However, the sample out-of-plane safety under earthquake-induced loads seems to be a matter of concern. 相似文献

对于贤相伊尹的研究,由于种种原因,仍处于误区之中。其一,多数介绍资料,都一致确认伊尹是有莘氏的家奴,善于烹调,以美味喻政治,因而得到成汤的重用。又有部分学者认为,伊尹为家奴说不可取,伊尹应是大巫,是宗教领袖,所以他能协助商汤灭夏建商。此说当今颇为流行。但证据不足,且从伊尹一生的政治生活来看,亦无相关行迹,因而此说也不可信。其二,伊尹放太甲于桐宫,三年见效,太甲复位,卒成名王;与另一说伊尹篡位自立,七年后太甲潜出,诛杀伊尹说,相提并论,缺乏选择与判断。后来虽有学者加以纠正,但论证力度不足,影响甚微。本文认为,伊尹本是夏朝贤臣,有高度的政治智慧,丰富的从政经验,他的离夏从汤,是明主与贤臣的双向选择,是历史的必然机遇。又认为太甲杀伊尹说证据不足,只有伊尹教诲太甲说是正确的。 相似文献
