抗震设计是整个建筑结构设计的重要内容,在设计工作中,非结构构件的抗震性能设计也是整个抗震设计的重要组成部分。现针对非结构构件在地震中破坏的现象、震害情况,分析破坏原因,给出了非结构构件的抗震设防目标。基于建筑物性能的基本思想,结合非结构构件的性能设计要求,讨论了非结构构件和附属设备的抗震设计基本计算要求,提出了相应的抗震设防技术措施,以提高其抗震能力。  相似文献

由于挑出结构构件本身具有较强的结构表现力,同时还可以避免在一定立面上设置竖向结构构件,因此,广泛运用于各种类型建(构)筑物中,对现代建筑的艺术造型产生了巨大的影响,利用挑出结构构件成为满足现代建筑造型的主要手段之一。文章着重论述了挑出结构构件在设计和施工中的常见问题,并针对挑出结构构件容易出现的问题,提出了较好的解决方法及注意事项。  相似文献

<正>在建筑结构设计中,设计人员要严格按照规范条文的规定进行设计。对于某些细部构造,设计人员可以直接套用标准图集,为设计者提供方便。对于建筑中的同一部位,不同行业的图集、做法等细部结构构造不尽相同。针对这种情况,笔者有以下几点看法:一、基础构件构造配筋通过结构计算得出的基础梁的截面一般比较小,为了保证结构安全,提高结构刚度和稳定性的一般做法就是加大构件截面,使构件获得较大的抗弯、抗扭惯性矩。如果基础构件  相似文献

在我国经济不断发展的情况下,建筑业也得到了一个很好的发展机会,伴随着建筑业发展的同时,建筑的相关技术也在不断的发展改革。建筑的钢结构是现在建筑施工当中使用最多的一种建筑结构类型之一,但是对于质量方面的要求,由于建筑钢结构构件和一般的建筑构件是不一样的,所以钢结构构件在进行设计和加工的过程当中也有着一些不一样的地方。为了能够提升建筑物的整体强度、安全性能以及尽量降低钢结构构件的运输费用,所以相关的设计加工单位就应该耍从钢结构构件的源头上来抓起,在钢结构构件的加工过程当中,做好相关的质量控制管理,从而来提升钢结构构件的质量,保证钢结构构件的性能。  相似文献

钢木复合结构是指不同部位结构构件采用钢、木两种材料,或是采用由钢、木为主导的两种不同结构形式的组合。在这种类型的结构中:木构件或木结构起主导作用,并且是建筑主要表现形式,通常决定着建筑的整体结构形式和空间造型;钢构件或局部钢结构往往作为辅助结构穿插于木结构体系中,保证主体结构的稳定性,并常应用于节点设计中。通过不同材料构成的结构构件或结构形式组合,最大限度的发挥各种材料的属性,弥补各自的力学缺陷,从而达到结构能效的优化。现主要分析了现代钢木复合结构的特点,钢木复合结构的安装施工方法以及现代钢木复合结构发展趋势。  相似文献

建筑工程施工质量非常关键,为了提高建筑质量很多工程中都应用了梁式转换层结构,在施工过程中要针对建筑需求,合理设计其抗震等级,同时明确对转换构件的构造要求,严格按照要求进行构件施工操作,完成操作后要对梁式转化层结构进行检查,保证施工操作无误。文章对梁式转换层施工技术在混凝土结构施工中的应用进行了探讨。  相似文献

概念设计是展现先进设计思想的关键,一个结构工程师的主要任务就是在特定的建筑空间中用整体的概念来完成结构总体方案的设计,并能有意识地处理构件与结构、结构与结构的关系。针对目前建筑结构设计当中墨守成规的现象,提倡采用概念设计思想来促进结构工程师的创造性,推动结构设计的发展。  相似文献

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.  相似文献

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.  相似文献

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.  相似文献

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders.  相似文献

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion.  相似文献

A new Office for National Statistics was created in the United Kingdom in 1996 following a series of developments designed to strengthen the relevance and integrity of statistics. This paper describes these fundamental changes and sets out a blueprint for future progress. It also sets current developments in the United Kingdom in an historical and international context.  相似文献
