对砌筑砂浆的几点认识

一、砌筑砂浆对砌体结构有着重大的影响 砌筑砂浆是指由胶凝材料、细骨料和水按适当比例配制而成,用于砌筑砖、石及各种砌体的砂浆。砌体结构是指用各种块材（主要是红砖）通过砌筑砂浆铺垫粘合而成的结构。 砌体在轴心受压时,由于砖表面不可能十分平整,所以当砂浆的厚度、饱满度、均匀度不十分规范时,砖实际上并不是处于我们想象中的面接触,而是点接触,是一种压,弯、剪的复合受力状态。这种复合受力状态,对脆性的砖相当不利,因为砖除了抗压性较好以外,抗弯、抗剪性能相当差,一旦由于弯、剪引起的主拉应力超过砖的抗拉强度,砖就…     

建筑材料的仓库管理

施工企业相对其他行业来说,是一种具较低附加值的行业,在其成本费用构成中,材料占70％甚至于更多,所以说材料管理是施工企业业务管理中的重中之重,加强材料管理,降低材料消耗是控制工程成本最重要的手段,对施工企业的盈亏起着决定性影响。而仓库管理又是材料管理中的重点。     

厄恩斯汀仓库，德国

这是德国北部一家便装零售公司的仓库。业主希望这个新的配货中心不仅在使用功能上合理,还应通过一定的设计手段展现出强烈的、有代表性的建筑形象。为此,业主邀请法比奥·赖因哈特(FabioReinhardt)、布鲁诺·赖希林(Bruno Reichlin)以及卡拉特拉瓦举行了一个立面设计竞赛,结果卡拉特拉瓦的方案中选。钢筋混凝土结构的仓库建筑本身是由格尔茨(Gerzi)设计的。卡氏设计的出发点是用单一的材料构成各自独立的立面。他所使用的未经加工的铝合金,是一种标准的工业材料。对这种材料进行不同的造型,产生截然不同的质感和光影效果,给本来形…

GIS and spatial data analysis: Converging perspectives

This article identifies some of the important developments in GIS and spatial data analysis since the early 1950s. Although GIS and spatial data analysis started out as two more or less separate areas of research and application, they have grown closer together over time. We argue that the two areas meet in the field of geographic information science, with each supporting and adding value to the other. The article starts off providing a critical retrospective of developments over the past 50 years. Subsequently, we reflect on current challenges and speculate about the future. Finally, we comment on the potential for convergence of developments in GIS and spatial data analysis under the rubric of geographic information science (GIScience).JEL Classification: C1, C31, C8

A distance correlation index of spatial dependence for compositional data

Geographical data in economic, social or environmental sciences are usually recorded as compositions, i.e. relative frequencies, and a common inquiring problem concerns the analysis of these data over different geographical regions. In the present paper we define a new statistical test to verify spatial dependence of such geographical distributions based on distance correlation, a recently introduced measure of dependence between random vectors. The proposed index computes the non-linear spatial distance between distributions and can be applied on compositional frequency distributions. Simulations and an application on Italian electoral data are presented, to illustrate the capabilities of the proposed test to detect spatial dependence.     

An analysis of pedestrian crashes using a spatial count data model

We develop a methodology to analyze pedestrian crash frequency in relation to neighborhood characteristics and exposure to traffic using a spatial count data model with a Poisson framework that is expanded to consider spatial factors, a methodological innovation. We also develop and apply a methodology for defining urban boundaries in mid-sized metropolitan areas, following the functionality of the urban area. These methodologies are applied to a case study. The case study identifies specific neighborhood sociodemographic characteristics associated with higher pedestrian crash frequencies. It also finds vehicle exposure to be insignificant. Results suggest that neighborhood-level planning policies may best address pedestrian crashes.     

Standard modularity is unsuitable for functional regionalization of spatial interaction data

Functional regions capturing local socioeconomic dynamics are a framework for territorial statistics and policy-making. The usefulness of such statistics and policies depends on the adequateness of the regions used in the analysis. Several authors have adopted the modularity quality function to drive their regionalization methods. This function, originally devised for non-spatial data, has limitations particularly relevant in this context. The paper discusses these limitations and illustrate them using real data for the United States. The results warn against using standard modularity to assess or optimize the quality of a functional delineation, and advocate for available alternatives that consider the spatial nature of functional regionalization.

Establishing a water information system for Europe: constraints from spatial data heterogeneity

Water information systems (WIS) are being developed for countries, international river basins and the European Union (EU), partly as a result of the requirements specified in the EU Water Framework Directive (WFD). The issue of whether and how these information systems should be integrated into the European Commission's water information system for Europe (WISE) is currently an open one. We present a discussion with regard to the challenges facing WISE development, with particular focus on the heterogeneity of spatial base data. In addition, an assessment of this heterogeneity is presented based on Swedish and English WFD reporting data, and on WISE‐relevant small‐scale European base datasets. Results show that WFD reporting data are based on incomparable methods and spatial analysis units, and that small‐scale data are transborder heterogeneous. Interpretation and international comparison of WFD results as well as their combination into a common WISE may therefore be largely constrained by spatial data heterogeneity.     

中国空间结构的发展与展望

论文阐述了我国空间结构的发展概况,结构类型和形式繁多,且不断创新,需要采用按单元组成方法来分类空间结构。21世纪后,我国空间结构的发展又进入一个崭新阶段,应用范围和领域不断扩大,除在体育场馆、航站楼等大跨度公共建筑中大量采用外,在新建大型铁路客站、无站台柱雨篷、桥梁结构工程和高层建筑结构中也获得创新应用。空间结构工程的国际合作方面,应以积极态度对待国外建筑方案屡屡中标我国空间结构工程的现象。由于多项空间结构之“最”在中国,表明中国已是空间结构大国,现正是加快迈向空间结构强国的最佳时机。展望中国的空间结构,提出了应着力关注和研究的问题。图41表8参19     

Analysing spatial spillovers in corruption: A dynamic spatial panel data approach

Previous studies on the determinants of corruption have seldom addressed cross‐border spillovers of corruption in a panel data setting. In this paper, we first propose a theoretical model of spatial corruption spillover based on network analysis. Then, we analyse spatial spillovers in corruption using a dynamic spatial panel approach. The results indicate that corruption not only exhibits spatial spillovers but also a persistent effect over time. More importantly, increase of income per capita, economic freedom, and percentage of women in the parliaments have a long‐term effect on the perceived levels of corruption. Policies and programmes aiming at abating corruption must take into consideration those results.
