嘉峪关光化楼残损变形现状及抗震性能分析

中国木结构建筑是我国宝贵的物质文化遗产和文化瑰宝，具有悠久的文化历史。以嘉峪关光化楼为依托，对光化楼进行实地调研，分析光化楼主要残损变形。采用ANSYS软件建立考虑光化楼残损变形的三维有限元精细模型，并进行模态分析与时程分析。研究结果表明，光化楼主要残损变形为油饰脱落、墙体剥蚀开裂、柱偏移等，极个别柱产生较大偏移；光化楼刚度相对稳定，前20阶振型自振频率均在10Hz以内；光化楼动力放大系数与层间位移角均较小，仍具有良好的抗震减震性能。     

The political geography of religion: historical state-church relations in Europe and recent challenges

Historical processes of state formation and nation building are crucial for an understanding of the geography of religions and churches in Europe. Each country has developed its own model of state-church relations, giving rise to a ‘bewildering variety’ as Grace Davie aptly remarks. The aim of this paper is to bring some order to this variety by developing a framework for the comparative study of church-state relations based on Stein Rokkan’s famous conceptual map and recent extensions of it to Central and Eastern Europe by John Madeley. According to that framework Europe has been divided into three mono-confessional (Roman Catholic, Lutheran, and Eastern Orthodox) blocs and two multi-confessional culture belts from Northwest to Southeast, and from Northeast to Southeast. This historical pattern has been challenged by secularisation, which started with the Enlightenment and the French Revolution (Western Europe) and the Russian Revolution (Eastern Europe until the velvet revolutions of 1989/1991) and then became widespread after the ‘cultural revolutions’ of the 1960s. A second challenge has to do with globalisation and its consequences, such as massive immigration and the rise of immigrant religions, and in general deterritorialisation, which means the disembeddedness of religion from its national territory. A third challenge concerns reterritorialisation at other (supranational, regional, transnational, and local) scales, of which the new territorial order of the European Union seems to be the most important. Finally, this paper serves as an introduction to the case studies on church-state relations in this special issue.

从集集地震看建筑物震害与地震动参数的关系

本文根据9．21台湾集集大地震中南投县、台中县、台北县和苗栗县的建筑物震害调查资料确定出这4个主要受害地区的平均震害指数,然后义计算出这4个地区的地震动峰值加速度、峰值速度、峰值谱加速度、峰值谱速度、峰值谱位移的平均值。将这些均值分别与平均震害指数进行基于最小二乘法的线性回归,发现峰值速度和震害指数有非常好的相关性,相关系数接近1．0,而峰值加速度与震害指数相关性只有0．8,这说明地震动峰值速度能够体现地震动对脆性结构的破坏势,与以往将不同次地震的记录和资料混淆在一起研究而获得峰值加速度与震害有很好相关性形成了对比。     

大型建筑物主轴线相关性问题研究

随着现代建筑施工技术的发展,建筑物的结构越来越复杂,对施工测量技术和方法的要求也越来越高.对于大型建筑群,尤其是连体建筑,要保证工程质量,不仅要对各建筑主轴线进行准确定位,还要考虑各主轴线的相关性.本文结合中新城上城项目,提出建筑主轴线相关性研究的一些方法,取得了预期的效果.     

电磁散射模型应用于单景高分辨率SAR影像建筑物高度反演的解算方法

首先,测量建筑物叠掩量,反演出建筑物高度初值;然后,在相邻建筑物下垫面粗糙度相关的假设下,对重组后的电磁散射模型进行基于拟模拟退火的参数解算,实现了模型中未知参数的求解以及建筑物高度的反演。将此方法应用于真实Radarsat-2SAR场景中3座建筑物高度的反演,取得了反演高度相对误差均小于10%的结果。     

Building extraction from LIDAR based semantic analysis

Extraction of buildings from LIDAR data has been an active research field in recent years. A scheme for building detection and reconstruction from LIDAR data is presented with an object-oriented method which is based on the buildings' semantic rules. Two key steps are discussed: how to group the discrete LIDAR points into single objects and how to establish the buildings' semantic rules. In the end, the buildings are reconstructed in 3D form and three common parametric building models (flat, gabled, hipped) are implemented.
