某大跨度挑台舒适度分析及振动控制

某景观挑台采用大跨度柔性悬挑钢结构,挑出长度约27m,在人行荷载及山区复杂风场下易发生结构竖向振动.人行荷载作用下的舒适度分析结果表明,结构竖向振动加速度大于规范限值,不满足舒适度要求;采取TMD减振措施后,结构的加速度响应得到了有效控制.根据数值风洞模拟得到的体型系数及Python编程模拟的风荷载时程,采用时域分析法进行风振分析,结果表明,结构振动加速度满足舒适度要求,风荷载单独作用下无需额外采取结构减振措施.人群荷载及风荷载共同作用时结构的竖向振动加速度稳定值小于0.5m/s2,但加速度峰值大于两种荷载分别作用时的加速度峰值之和,因此人行荷载及风荷载对结构的影响不能简单叠加,必要时应进行两种荷载共同作用下的振动分析及减振控制.

Life cycle assessment: A case study of a dwelling home in Scotland

The article provides a life cycle assessment (LCA) of a 3-bed room semi detached house in Scotland. Detailed LCA of five main construction materials i.e. wood, aluminium, glass, concrete and ceramic tiles have been provided to determine their respective embodied energy and associated environmental impacts. Embodied energy of various construction materials involved has been estimated to be equal to 227.4 GJ. It is found that concrete, timber and ceramic tiles are the three major energy expensive materials involved. It as been calculated that concrete alone consumes 65% of the total embodied energy of the home while its share of environmental impacts is even more crucial.

Governing the project process: a conceptual framework

There has been considerable development in a process approach in construction management research in recent years. However, such work begs the question of how those processes are governed. Processes, be they flows of information or materials, need to be channelled in the desired direction as they are handed from team to team. This paper aims to present a conceptual framework for understanding the governance of construction project processes, drawing on transaction cost economics. Earlier attempts to apply this theoretical framework in construction management research have been partial, in that they have focused on only one type of transaction, typically that between client and principal contractor. This paper aims to be comprehensive in covering all the different transactions throughout the project lifecycle within one conceptual framework, and thereby it is hoped that more incisive empirical research can be developed and executed.

Building simulation as assistance in the conceptual design

In order to realize the “design by simulation” concept in the building design, the methodology of applying the building simulation in the building’s conceptual design stage is the main theme discussed in this paper. The conceptual design stage is divided into four sub-stages, and the framework of the design is built by way of the simulation in the conceptual design stage. Moreover, the energy saving potential assessment by the simulation in the preliminary conceptual design stage is also discussed in detail, including the input/output information, the calculation method and procedure, and the requirements and information from architects, etc. The natural ventilation design is used as the first trial in this study, and the difference between the detailed conceptual design and the preliminary conceptual design is also discussed, and the new simulation methodology is further described. The main objective of this paper is to help avoid an incorrect decision in the conceptual design stage, as well as to provide a better base for the energy efficient design in the next stage by means of the building simulation tool.     

城市机动性--城市研究的新概念框架

对城市中日常出行和交通运输问题的认识,正在摆脱工程师的技术观念束缚,成为社会科学的一项研究内容.社会学、地理学、心理学、经济学等多学科的研究方法催生了一个新的概念:城市机动性.城市的交通出行不仅是一个技术问题,而且是一个社会问题.对这一问题应当通过人们的城市生活方式,在空间中的表现,环境导向认知等方面进行研究.城市机动性的概念促使城市研究学者采用一个更加整体和系统化的方法来对待交通问题:城市交通不能脱离技术条件的支持(交通运输)、城市社会活动的组织(布局结构)、城市居民的日常活动(城市社会活动),空间质量(城市景观)以及城市决策者的管理措施(城市政策).城市机动性因此提供了一个概念性的框架.在此基础上可以发展建立新的概念与认识,如"交互的机动性"和"多类型的机动性"的概念.

Fragile cities in the developed world: A conceptual framework

Cities, like any complex adaptive systems, may become increasingly fragile if not properly managed. To date, the literature has focused primarily on the examination of cities within fragile countries. This has resulted in a dearth of studies that have looked at how developed (or even advanced) cities that operate in relatively stable countries and/or environments might allow unresolved issues to accumulate in the city: degrading its ability to function. Studying fragility in developed cities is a worthwhile undertaking given their economic, social, and political significance. This paper puts forth a conceptual framework to understand the nature of fragile cities in the developed world. Our framework frames fragility as a function of unresolved fractures of social compacts that degrades a city's ability to function over time and stress exacerbates its effects. Drawing on over two dozen incidents from developed cities, we ground the framework and illustrate its value.     

Fire risk analysis: General conceptual framework for describing models

A general conceptual framework has been developed as an aid to discussions of alternative approaches to fire risk analysis. The purpose is to show how each alternative seeks to address a few common concerns. Basic concepts and key elements — notably scenario structures, appropriate probability functions, and security and outcome measures — are defined and discussed, as are types of modeling approaches. Anumber of diverse examples are then presented using the framework to illustrate its value in making comparisons.     

Residential inequality in Sweden: A conceptual distinction

This article focuses on two concepts that have been used to study the living conditions of different social groups in Sweden, “residential segregation” and “housing market segmentation”. Distinctions between the two concepts are made in reference to four areas. Although the relation of the groups in question to a basic social inequality is a point of contention in the tradition of residential segregation, when it comes to housing market segmentation the literature more clearly points to a basic inequality in society. Both concepts imply a certain physical hierarchy associated with the residential living of specific social groups. In reference to both concepts one can point to additional attributes that make one or more residential areas or particular form of tenure more advantageous or attractive than others. Finally in reference to residential segregation one would generally assume that the extra benefits from living in a higher quality area would cost more. A similar assumption, however, cannot be made using the concept of housing market segmentation. The attempt to highlight questions of housing tenure by considering them under a separate concept has clear merits. The next step is to explore how these two phenomena, in some circumstances, interact with each other.     

Urban growth and manufacturing change in the United States-Mexico borderlands: A conceptual framework and an empirical analysis

This article is a contribution to the study of urban and manufacturing evolution that develops and applies the author's concept of the urban-manufacturing life cycle. This concept relates internal characteristics and external impacts of the urban manufacturing base to the process of urban growth by considering the most significant variables and their changes over time. Emphasis is also placed on process-oriented evolution and general relevance rather than outcomes. An application to the general study of border cities with distinct levels of development follows a review of the urban and regional growth literature, as an initial contribution to the development of an evolutionary theory of borders. Empirical analyses with longitudinal data for five major United States and Mexican border urban clusters then evaluate the general assumptions of the concept. Growth trends in urban population, sectoral employment shares, urban industrial structure, employment, and number of manufacturing plants are examined in each of the cities and urban clusters considered. The study concludes that the empirical analyses generally verify the assumptions of the urban-manufacturing life cycle.     

Understanding consumption-related sucralose emissions — A conceptual approach combining substance-flow analysis with sampling analysis

This paper explores the potential of combining substance-flow modelling with water and wastewater sampling to trace consumption-related substances emitted through the urban wastewater. The method is exemplified on sucralose. Sucralose is a chemical sweetener that is 600 times sweeter than sucrose and has been on the European market since 2004. As a food additive, sucralose has recently increased in usage in a number of foods, such as soft drinks, dairy products, candy and several dietary products. In a field campaign, sucralose concentrations were measured in the inflow and outflow of the local wastewater treatment plant in Linköping, Sweden, as well as upstream and downstream of the receiving stream and in Lake Roxen. This allows the loads emitted from the city to be estimated. A method consisting of solid-phase extraction followed by liquid chromatography and high resolution mass spectrometry was used to quantify the sucralose in the collected surface and wastewater samples. To identify and quantify the sucralose sources, a consumption analysis of households including small business enterprises was conducted as well as an estimation of the emissions from the local food industry.The application of a simple model including uncertainty and sensitivity analysis indicates that at present not one large source but rather several small sources contribute to the load coming from households, small business enterprises and industry. This is in contrast to the consumption pattern seen two years earlier, which was dominated by one product. The inflow to the wastewater treatment plant decreased significantly from other measurements made two years earlier. The study shows that the combination of substance-flow modelling with the analysis of the loads to the receiving waters helps us to understand consumption-related emissions.
