1不同规范组合梁抗火设计方法的比较和分析显示文摘首先介绍了中国规范、欧洲规范和英国规范中的组合梁抗火设计方法,并通过算例对比了根据各国规范预测的临界温度和耐火极限。对比发现:对于常温下按完全剪力连接设计的组合梁,各国规范计算出的临界温度相差不是很大,其中欧洲规范的计算值最高,而英国规范的计算值最低。对于常温下按部分剪力连接设计的组合梁,以中国规范中承载力法得到的临界温度可能不安全,建议增加对高温下剪力连接件抗剪承载力的验算;而以中国规范中临界温度法得到的临界温度过于保守,建议将中国规范中临界温度法推荐的表格适用范围局限于常温下按完全剪力连接设计的组合梁。陈玲珠 蒋首超 李国强 Gianluca Ranzi 2015防灾减灾工程学报2015,35,1:8
2高温下钢筋桁架楼承板中栓钉抗剪性能研究显示文摘对15个试件进行常温和高温下推出试验,研究钢筋桁架楼承板中栓钉的抗剪性能,得到混凝土楼板和栓钉不同位置处的温度分布以及栓钉受剪承载力随温度的退化规律。试验结果表明,钢筋桁架楼承板中栓钉在常温和高温下的破坏均为栓钉剪断破坏,栓钉根部混凝土局部压碎,但是与平板混凝土板中栓钉的破坏位置不同,所研究的栓钉剪断破坏的位置在钢梁上翼缘处,而不是在栓钉根部焊缝处,这也在很大程度上导致了钢筋桁架楼承板中栓钉受剪承载力比平板混凝土板中栓钉低。钢筋桁架楼承板中栓钉的受剪承载力和刚度均随温度的升高而降低。通过对试验数据的分析,提出了钢筋桁架楼承板中栓钉高温下受剪承载力和荷载-滑移曲线的计算方法。陈玲珠 李国强 蒋首超 王卫永 RANZI Gianluca 2015建筑结构学报2015,36,5:6
3A day-ahead scheduling framework for thermostatically controlled loads with thermal inertia and thermal comfort model显示文摘This paper proposes a day-ahead dispatch framework of thermostatically controlled loads(TCLs) for system peak load reduction. The proposed day-ahead scheduling framework estimates the user’s indoor thermal comfort degree through the building thermal inertia modelling. Based on the thermal comfort estimation, a dayahead TCL scheduling model is formulated, which consists of 3 stages: TCL aggregator estimates maximal controllable TCL capacities at each scheduling time interval by solving a optimization model;[ the system operator performs the day-ahead system dispatch to determine the load shedding instruction for each aggregator;and ′the TCL aggregator schedules the ON/OFFcontrol actions of the TCL groups based on the instruction from the system operator. A heuristic based optimization method, history driven differential evolution(HDDE)algorithm, is employed to solve the day-ahead dispatch model of the TCL aggregator side. Simulations are conducted to validate the proposed model.Yingying CHEN Fengji LUO Zhaoyang DONG Ke MENG Gianluca RANZI Kit Po WONG 2019Journal of Modern Power Systems and Clean Energy2019,7,3:3
4组合梁抗火设计方法的改进显示文摘通过对现有组合梁抗火设计方法的总结和对比分析发现,中国规范和欧洲规范中承载力法在构件温度和承载力的计算上都基于相同的理论,只是某些参数的取值不同,最大的区别在于欧洲规范强调了对高温下剪力连接件抗剪承载力的验算,中国规范则没有考虑这一影响,而英国规范则基于试验研究的结果,给出了近似的计算公式。对于临界温度法,各规范均以表格或简化公式形式给出了临界温度计算方法,但只有英国规范考虑了常温下抗剪连接程度的影响。通过将各规范计算结果与现有相关试验结果进行对比发现,组合梁抗火设计时,应考虑常温下抗剪连接程度的影响;在现有中国规范组合梁抗火设计方法中考虑常温下剪力连接程度后,能更准确地预测组合梁的临界温度。陈玲珠 李国强 蒋首超 王卫永 Ranzi Gianluca 2015建筑结构2015,45,11:2

11Upstream Operations in the Oil Industry: Rigorous Modeling ofan Electrostatic Coalescer显示文摘This paper deals with a first-principle mathematical model that describes the electrostatic coalescer unitsdevoted to the separation of water from oil in water-in-oil emulsions, which are typical of the upstreamoperations in oil fields. The main phenomena governing the behavior of the electrostatic coalescer are denscribed, starting from fundamental laws. In addition, the gradual coalescence of the emulsion droplets isconsidered in the mathematical modeling in a dynamic fashion, as the phenomenon is identified as a keystep in the overall yield of the unit operation. The resulting differential system with boundary conditionsis then integrated via performing numerical libraries, and the simulation results confirm the available lit-erature and the industrial data. A sensitivity analysis is provided with respect to the main parameters. Themathematical model results in a flexible tool that is useful for the purposes of design, unit behavior predic-tion. performance rnoniroring, and ontimization.Francesco Rossi Simone Colombo Sauro Pierucci Eliseo Ranzi Flavio Manenti 2017Engineering2017,3,2:1
