工程地质勘察在房建工程中的运用

近年,随着我国城镇化建设工作不断深入开展,带动了建筑行业的快速发展,将工程地质勘察技术运用在房建工程建设过程中将会对整个建筑行业产生不容小觑的影响,这将从根本上提升我国房建工程的建设品质,减弱负面作用。提升房建工程的地质勘查工作能够为房建工程提供一定的保障,帮助整个行业得到快速有效的发展。文章以工程地质勘察的现实状况为入手点,对其影响房建工程的机制进行了研究与分析。     

SP牌坊开裂机理与维修策略

从物理力学、应力测试、有限元模拟三方面分析计算了SP牌坊的受力及应力情况，再通过对应力及裂纹断口的分析得出：高周疲劳是SP牌坊开裂的根本原因。以理论与现场实际相结合，研究出了SP牌坊开裂有效修补方案，通过该修补方案的实施，牌坊本体上的应力水平降低了40％，且对拍击振动也较不敏感，修补维修策略有效。     

纯电动汽车两挡变速器壳体强度分析与改进

在电动汽车变速器优化设计的研究中,变速器壳体的强度对变速器的传动性能有重要影响.纯电动汽车两挡变速器壳体结构较复杂,且受力极不均匀,难以用传统的解析方法对其进行强度计算.针对上述问题,提出利用有限元法对变速器壳体进行强度分析.研究了两挡变速器的结构及工作原理,计算了极限工况下壳体轴承座载荷,建立了壳体的三维实体模型及有限元模型,得到了壳体的应力分布云图,确定了壳体强度的薄弱环节,并据此提出了改进方案.结果表明:改进后的变速器壳体强度得到了改善,并实现了产品的轻量化,为变速器壳体的设计及生产提供了理论依据.     

从"为大众的住宅"到"为大众的社区"从"居住区规划"到"社区建设"

在历经20年的建设后，中国的城市住房在数量和质量方面都有了飞跃发展，但同时，城市的富裕居民和贫困居民在住房条件上的鸿沟也日益加大。有鉴于美国在住房建设方面的经验，文章提出应制定一种侧重于社会发展的住房新政策，并提出“为大众的社区”和“社区建设”的概念。     

住宅设计原理——“住”的思考

居住类建筑一直是建筑设计人员关注的重点,关于"住"的思考人们也从未停歇过,将结合一些流行的住宅设计观点展开对于"住"的思考.     

预制混凝土结构插入式预留孔灌浆钢筋搭接试验

为研究具有自主知识产权的预制混凝土结构钢筋连接方法,在钢筋锚固试验结论的基础上,设计制作了108个预制混凝土结构插入式预留孔灌浆钢筋搭接试件。依据搭接接头率为100%的要求确定了钢筋搭接长度,考虑了钢筋直径、混凝土强度、搭接长度等不同影响因素,完成了试件的单向拉伸试验,得到了插入式预留孔灌浆钢筋搭接连接的破坏模式及各因素的影响规律,计算分析并给出了合理的搭接长度。通过实验证明,插入式预留孔灌浆钢筋搭接的方法,其连接性能可靠且施工简便,适合于住宅产业化下的预制混凝土结构的钢筋连接。     

Eurohypothec: Drafting a Common Mortgage for Europe

The virtual lack of cross-border mortgage lending in the European Union (E.U.), even before the current mortgage and financial crisis, reveals the need to adopt a pan-European mortgage instrument. This article shows how it can be structured such that a common mortgage instrument for Europe could lead to the construction of a true pan-European cross-border mortgage market. It is the so-called Eurohypothec. The model is studied following the objectives pursued by the E.U. White Paper about the integration of the E.U. mortgage credit markets and also taking into account the causes of the current mortgage and financial crisis (mainly weak legal structures of mortgage securitization processes and their control, in addition to the lack of transparency in mortgage lending). The paper also shows how operations using or based on mortgage loans can be done efficiently, securely, and transparently throughout Europe through the so-called Eurotrust. In conclusion, the writer finds out that the combination of Eurohypothec and Eurotrust is fully compliant with the E.U. White Paper. Moreover, this combination could not only help with the creation of a true pan-European mortgage market but also would help to enhance current national mortgage legislations and to make more transparent and secure several financial operations that involve mortgages.     

CBR Revision Model for Improving Cost Prediction Accuracy in Multifamily Housing Projects

For any construction project to succeed, it is very important to accurately estimate the construction cost during the project’s initial stage. This is why there has been much interest lately in cost prediction models that use case-based reasoning (CBR). It has been pointed out, however, that existing CBR-based cost prediction models may yield inaccurate results even though they could survey optimal similar cases, if the number of cases in the case base is not enough. As opposed to the existing CBR-based construction cost prediction models, this study developed a CBR revision model that reflects the “revise” phase of the CBR cycle (retrieve, reuse, revise, and retain) based on nine multifamily housing projects executed recently by “A” Housing Corporation. To verify the developed model, a case study was performed using three case projects completed by “B” and “C” Housing Corporations. The result showed that the prediction error ratio after the Revise (I) phase decreased from 97.44 to 22.58%. This model can be effective when there are insufficient established cases in the case base.
