采用三维非线性有限元分析方法评价与估算了桥面板与混凝土覆层间结合界面的干燥收缩诱导应力,并采用修正Fowler准则测算了桥面板与聚合物覆层间的热诱导应力。在评价覆层与面板间相对厚度to/ts的影响时,ts取常数200 mm;在评价相对弹性模量Eo/Es的影响时,Es取常数,27.5 GPa,并设定了3个Eo/Es比值,分别是0.5,0.75,1.0。在评价每个Eo/Es比值的影响时,考虑3个to/ts比值,其值分别为0.281,0.375,0.45,并对应3个覆层厚度值,分别为55,75,3.6,90 mm。结果表明:收缩诱导剪切应力与黏结应力随Eo/Es比值及to/ts比值的增加而增加;有限元分析结果与修正Fowler准则测算结果表现出相同的变化趋势,但由前者估算的黏结应力要比由后者估算的高很多。对诱导黏结应力有重要影响或者会导致黏结强度下降的其他因素也进行了深入讨论。

工业项目一直是非洲许多国家的经济支柱,但为了使该国的工业部门蓬勃发展,需要建立有利的投资环境,例如建设更大的现代化海港和机场,提供可靠的公用事业和其他配套产业实体,如建立有竞争力的现代工业园区,以激励产业投资。但是,这种投资规模太大,仅靠政府征税、以政府机构作为项目技术实施主体是难以应对的。因为,这些类型的投资需要大量资金、高技能人才和国家承诺,这就是为什么如果不应用项目管理技术和工具来规划和控制这些项目,就会面临无法实现的高风险。富有成果的国家期望。然而,政府管理下的项目执行不力似乎是桑给巴尔的普遍情况。审计报告显示,大部分政府全额融资项目超预算、超法、超时、亏本经营。尽管政府努力审查它的发展政策并提高其人民的技术技能并用工具和设备促进他的机构,但如果没有适当的项目计划,上述努力不足以避免政府项目失败。本研究旨在评估风险并在Pangatupu工业园区(CPIP)项目建设中应用项目管理工具,该项目是桑给巴尔革命政府(RGo Z)正在进行的项目之一。在这个项目中执行的项目管理应用是工作分解结构(WBS)的准备,其中项目可交付成果被分解为易于执行的工作包,责任矩阵(RM),其中每个项目工作包的责任分配给各自的政府机构,并通过使用Proffhub项目软件,还设计了甘特图。还确定了项目任务之间的关系。此外,在控制CPIP项目的进度过程中,网络图中的关键路径方法(CPM)被应用于通过查找和控制CPIP项目中的最长路径来控制项目时间范围。因为,确定项目的关键路径是在预计时间和预算内成功完成项目的关键。CPIP项目控制进度时间结果表明,该项目可比预计完工时间提前24天完工。最后,通过识别潜在风险及其对项目的影响,对Pangatupu工业园区建设进行风险评估,并提出控制缓解方案。识别出的潜在风险之一是经济风险、建设和收缩现场风险、管理风险、技术风险和政治风险。成功的风险管理导致在预计的时间、预算内并以良好的质量完成了项目。

THE EFFECT OF OCCUPANCY ON ELECTRICITY USE IN THREE CANADIAN SCHOOLS

引用

Journal of Green Building 2018年第1期13卷 95-112页

作者： Mohamed Ouf Mohamed H.issa Phil Merkel Panos Polyzois Department of Civil Engineering University of Manitoba15 Gillson StreetWinnipeg MB R3T 5V6 Canada Customer Engineering Department Manitoba Hydro

Through building performance simulations, previous studies showed the effect of occupants on buildings’ energy consumption. To further demonstrate this effect using empirical evidence, this study analyzed the effect of occupancy on real-time electricity consumption in three case-study schools in Manitoba. Within each school, one classroom as well as the gymnasium were sub-metered to collect real-time electricity consumption data at half-hourly intervals. The study focused on electricity consumption for lighting and plug loads, which make up 30% of energy consumption in Canadian commercial and institutional buildings. A comprehensive method was developed to investigate energy-related occupant behaviour in the sub-metered spaces using four different tools simultaneously: 1) gymnasium bookings after school hours over a four-month period, 2) half-hourly observations of lighting and equipment use in the sub-metered spaces in each school over a two-week period, 3) a daily survey administered to teachers in the sub-metered classrooms over a two-week period, and 4) occupancy and light sensors to evaluate actual recorded occupancy and light use durations over a four-month period. Results showed that recorded occupancy durations over a 4-month period only explained less than 10% of the variations in classrooms’ lighting electricity consumption, meaning that lights may have been used frequently while classrooms were unoccupied. Results also showed the differences in gymnasiums’ electricity consumption were still statistically significant between the three schools, even after school hours and when the gymnasiums were not used or booked for other activities. This study is the first to provide in-depth evaluation of the effect of occupancy on electricity consumption in Canadian schools.
