从“场地特定”到“场地决定”——建筑之于场地的可能性

借用雕塑与场地之间关系的四种类型,描述并分析了建筑创作中对待建筑与场地之间关系的态度及方法,结合日本导盲犬中心等建筑案例,强调了“场地决定”的意义以及从“场地特定”向“场地决定”的进化,并论述了自然以及对自然的关注在其中的积极角色,类比了农耕景观的特性,呼吁一种新标准理性的产生。     

凝析油输油管道方案的选择

分析凝析油管道输送和油罐车输送的优缺点,以实际工程为例,对凝析油管道加热输送进行水力计算和热力计算。在满足输送压力和温度要求的前提下,利用管道输送,中间不需设置加压泵站和加热站即可满足输送要求。既节省造价和输送成本,又充分利用了规划路由,凝析油采用管道输送是可行的。     

Simplifications for hydronic system models in modelica

Building systems and their heating, ventilation and air conditioning flow networks, are becoming increasingly complex. Some building energy simulation tools simulate these flow networks using pressure drop equations. These flow network models typically generate coupled algebraic nonlinear systems of equations, which become increasingly more difficult to solve as their sizes increase. This leads to longer computation times and can cause the solver to fail. These problems also arise when using the equation-based modelling language Modelica and Annex 60-based libraries. This may limit the applicability of the library to relatively small problems unless problems are restructured. This paper discusses two algebraic loop types and presents an approach that decouples algebraic loops into smaller parts, or removes them completely. The approach is applied to a case study model where an algebraic loop of 86 iteration variables is decoupled into smaller parts with a maximum of five iteration variables.

Strategic IT implementation decisions for major construction projects in Hong Kong are subject to various forces or factors identified in previous research—such as external forces, technological factors and organizational factors. The aim of this research was to examine the relationship (if any) between these families of forces and evaluate their impact, individually and collectively. A complex combination of several families of forces/factors that affect decision making was found to be ‘temporal’ with respect to project teams on major projects in Hong Kong. The research was underpinned by a broad questionnaire survey to establish ‘current practice’ before in‐depth analysis of the forces by means of a case study followed by interviews with industry leaders to confirm the results. It was found that respondents (n = 33) ordered cost, security and confidentiality as the most influential factors affecting IT implementation. A difference was found in the perceptions of ‘hired‐in’ project‐based staff in joint ventures and ‘permanent staff’ of single companies, the former evaluating IT performance more highly but evaluating the strategic use of, and user satisfaction with, IT significantly lower. The major constraint on IT implementation was found to be lack of budget, not cost per se. It is concluded that the temporal factors that apply to implementing innovative IT technology in project teams are relevant to different team members at different stages in the project life cycle and these factors are conditioned by a set of business conditions applying to project‐specific coalition organizations that are different from those that apply to single‐entity organizations.

塔夫里与柯布西耶——关于建筑的现代性

本文试图勾勒威尼斯建筑学派的领导人物塔夫里如何透过柯布西耶的系列研究发现,塔夫里对人们习以为常的观念,提出了不同的诠释与批判,像乡愁、场所、涵构、技术、自然与乌托邦等概念。最后,塔夫里指出必须在城市的尺度上解决现代性的问题,权力的集中与公共部门的整合是必然的。这却与此刻时代的走向相龃龉。     

定制:传统与融合

本文研究了在"自然"视角下的挪威建筑。纵观20世纪,各种各样的环境意识涌现在建成环境和建筑理论中。今天,挪威建筑制造中对自然的运用、阐释和理解的理念在挪威建筑师中几乎已成为一种神话。要从建筑的关系上探讨"自然"的用法和涵义,可以将它解析为自然三相:自然之实、自然之道和自然之象;而这些语汇可以在最近挪威建筑的具体实例上进一步展开。     

中西自然观发展脉络初论——兼论我的自然观

本文梳理了中西传统自然观的发展脉络,比较了中西传统自然观的差异——"重人"与"重神"、"自然"与"祂然"、"求善"与"求真",论述了西方自然观引入中国并持续扩大其影响的7个事件,分析了现代自然观的3个特征——有机、过程、系统,提出了作者的"12事自然观"。     

超细水泥活性粉末混凝土的配合比设计

为了使原材料来源更好地满足实际工程需要,通过试验成功制备了不掺硅粉的新型超高性能混凝土,即超细水泥活性粉末混凝土（SC RPC）,并研究了水胶比、砂胶比、外加剂掺量、骨料粒径范围、普通水泥及矿物掺和料对SC RPC砂浆体抗压强度、（含水）孔隙率、拌和物流动度的影响.试验结果表明：超细水泥可单独作为粉料制备SC RPC;混掺30%（质量分数）粒化高炉矿渣粉、10%（质量分数）粉煤灰后材料抗压强度最高,拌和物流动度最大,且经济性较好;采用普通水泥取代部分超细水泥导致材料孔隙率增大,抗压强度降低;可针对工程需要筛分出粒径范围合适的普通河砂制备SC RPC;建议使用适量消泡剂增加材料密实度.在试验基础上建立了水胶比、孔隙率双因素控制的SC RPC砂浆体抗压强度预测模型,并给出掺入钢纤维后材料抗压强度的计算方法.
