钢筋混凝土柱的“强剪弱弯”可靠性区间分析   总被引:1,自引:0,他引:1  
易伟建  李浩 《工程力学》2007,24(9):72-79
在钢筋混凝土结构抗震设计中,"强剪弱弯"是保证结构延性的一个重要设计概念。引进区间变量表达认知不确定性,对钢筋混凝土框架柱进行失效概率区间分析。通过结合代表认知不确定性的区间变量与代表偶遇不确定性的随机变量完成了对不确定性的数学描述。在此基础上,根据对基本事件的包含关系建立"强剪弱弯"区间可靠性概率模型,并从证据理论出发论证了该失效概率区间的上下界实质上等价于证据理论中的信任与似然函数。对于含有区间值不确定性参数的结构承载力计算,将Berz-Taylor模型引进计算过程中,减少由于区间扩张而导致的误差。在数值模拟计算中,运用模拟退火遗传算法(SAGA)确定了"强剪弱弯"的大致设计区间。根据该设计区间构造了特殊的采样函数进行重要性采样模拟从而得到了失效概率区间。误差分析表明该方法具有较好的精度。最后通过算例分析了各设计因素对"强剪弱弯"可靠性的影响,并提出了相应的设计建议。  相似文献

 公理化设计理论与TRIZ在产品设计开发中都有其优势及局限性。公理设计在系统性地生成概念初始方案方面有优势,TRIZ在解决设计中出现的冲突方面有优势。提出了集成公理化设计理论与TRIZ解决设计问题的一种方法。首先应用公理设计理论形成设计的概念初始方案;其次分析所得设计方案中可能存在的冲突,并分清冲突的类型是物理冲突还是技术冲突;然后对不同的冲突采用相应的冲突解决原理来解决;最后重新设计新的设计参数来消除冲突。通过液压修井机设计实例说明了这种方法的有效性。  相似文献

如何理解设计学科专业的对应调整,尤其是对交叉学科“设计学”对应调整意图的解读,从学科专业建设与发展角度来说十分必要。就实施政策来看,其着眼点就在于建设新的学科体系,凸显设计专业博士学位点的实践性功能,并促进设计学尽快融入交叉学科。对此,整个对应调整工作的重心,必然是平衡且凸显学科专业与社会发展紧密联系的优势,拓展应用领域、补齐教学短板、完善学科体系,这是设计学科专业体系在发展中层层革故鼎新、去芜存菁的思考方向。依此来看,交叉学科“设计学”的设置,就有着极大的调整与自主作为的空间,其学科交叉发展策略应当是比较清楚的,诸如,“设计学”交叉学科 +“设计”艺术的开启,显示出新版学科专业目录下的设计学,从艺术学门类调整到交叉学科大类,这明显是将传统意义上的设计学进行了剥离,从而推向适应未来高科技和社会服务发展时代需求,设计学将在国家规划战略中发挥出举足轻重的作用。  相似文献

This study employs social network analysis to identify institutions with strong international collaborative relationships in astronomical research. We find that the strongest ties tend to link institutions across continents in research collaboration. However, the effect of geographic factors is still notable in light of the fact that most of the institutions in the largest subgroup are located in Europe. Examination of the network position, measured by degree centrality, indicates that homophily is more common than heterophily in the network. A relatively high number of relational ties are observed among institutions that have similar levels of network centrality. Mutual relations are prevalent among central institutions, while strong mutual solidarity exists between institutions on the periphery of the network. This study shows a general unstable international collaborative relationship among astronomical institutions. While more and more institutions have linked up in research collaboration, many of them keep relatively weak ties. Institutions tend not remain in the same subgroup, but link to different partners over time.  相似文献

Collaborative product development (CPD) processes are generally based on technological infrastructures. Various information technologies (IT) are proposed every day to facilitate collaboration, integration, co-design and co-development processes. In this highly uncertain environment, a systematic methodology is essential to plan the IT infrastructure needed to start and maintain a collaborative process. This study offers an integrated IT planning methodology combining fuzzy quality function deployment, fuzzy axiomatic design and fuzzy rule-based systems. The methodology is tested in a CPD case and the outcome presents an improvement path for IT for each of the collaborative parties.  相似文献

The literature is replete with examples of collaborative studies and research from 1960 to about 1995, after which the movement seems to have lost momentum. With the emergence and focus on patient safety issues, the importance of collaboration and a team approach to patient care has become paramount. CRM is a communication methodology developed by the aviation industry, based on team-centered decision making systems. Once we have identified the key components of a successful collaborative model, it is imperative that we incorporate them into the health care providers' educational curriculum, both in training as well as in the practice setting. Effective communication must be identified as a necessary skill, and collaboration as a conscious, learned behavior. The dream of collaboration has been deferred long enough, and CRM shows promise for re-igniting the collaborative movement.  相似文献

Computer-supported cooperative work (CSCW) systems are computer-based tools that support collaborative activities. They should meet the requirements of normal collaborative efforts among people. They should not only support virtual face-to-face collaboration among people at a distance, but also improve face-to-face collaboration by providing more mechanisms to overcome the drawbacks of face-to-face collaboration among people. Therefore, introducing roles into CSCW systems is extremely important. By roles, one can avoid users of CSCW systems being overwhelmed by too much irrelevant information. One of the major problems in current CSCW systems is determining how to define and specify roles clearly and rigorously while maintaining the flexibility for collaboration. Many traditional CSCW systems based on roles have lost their flexibility after introducing roles because they can only provide static role mechanisms based on intuitive role concepts. There are no flexible mechanisms for role tuning, changing and transitions because there is not a special mechanism to express a role. This paper reviews the applications of roles in traditional collaborative systems, clarifies the general meanings of roles, discusses the functions of roles in collaboration, and suggests a role mechanism and a group of principles to support collaboration based on roles. This paper concludes that roles need more comprehensive research and will be applied widely in different areas.  相似文献

Facing intensified global competition, firms strive for greater supply chain collaboration by leveraging the resources and knowledge of key suppliers and valued customers to reduce uncertainty, lower transaction costs, build core competence, capitalise on opportunities for learning and knowledge creation, and improve competitive position. This study examines the nature and characteristics of supply chain collaboration. Through an extensive literature review, it conceptualises supply chain collaboration as seven interconnecting elements: information sharing, goal congruence, decision synchronisation, incentive alignment, resource sharing, collaborative communication, and joint knowledge creation. It develops valid and reliable instruments to measure supply chain collaboration through rigorous empirical and statistical analysis including structured interviews, Q-sort, and a large-scale study. Predictive validity is evaluated by demonstrating a strong and positive relationship between a firm's level of supply chain collaboration and its performance. The definitions and measures that result provide a rich and structured understanding of supply chain design and operation. They also facilitate empirical research and provide analytical consistency that enables greater sharing and comparison of research results.  相似文献
