1高层建筑抗风设计中存在的问题与对策探析显示文摘风荷载与风致加速度响应越来越成为高层建筑主体结构与围护结构设计的主要控制性指标。工程技术人员能否选择适合具体项目的风洞试验单位,是否具备审核风洞试验方法与试验结果的能力越来越影响高层建筑抗风设计的安全性与经济性。首先指出了规范GB 50009—2012在实际工程应用中存在的不足,主要包括远场地貌类别、阵风风速剖面、风速风向折减因子、围护结构极值负压与气动阻尼比等参数,然后基于实际项目案例给出风洞试验过程中出现的一些问题,例如测试技术与分析参数的选取、设备故障判断与第三方独立试验,最后针对性的给出相关建议,可为相关技术人员进行风洞试验管理与报告结果校核提供参考。张正维 杜平 Andrew Allsop 2018建筑结构2018,48,18:7
2重庆来福士广场抗风设计显示文摘通过对重庆来福士广场项目的风气候分析、复杂地形风洞试验、多天平风洞试验、高频压力积分试验与第三方风洞试验,得到了等效静力风荷载与加速度响应,分别采用频域与时域方法分析了复杂连体多塔结构的风致响应,并对结果进行包络设计。单塔结构的测力天平与测压试验结果吻合性较好,多塔连体结构的第三方风洞试验与原有试验的平均值与背景值吻合较好,说明了试验方法的合理性。还在时域中采用LS-DYNA对塔楼与连桥之间的隔震支座在风荷载作用下的性能进行了研究。分析结果为重庆来福士广场项目设计提供了安全经济合理的设计风荷载。张正维 杜平 Andrew Allsop Francois Lancelot 凤多多 2015建筑结构2015,45,24:5
3高层建筑围护结构风压规范比较与工程应用显示文摘风荷载是高层建筑围护结构设计的主要控制荷载。中国《建筑结构荷载规范》(GB 50009—2012)给出了单体矩形截面高层建筑围护结构的设计风荷载,其中迎风面正压与分离区负压都随着建筑高度的增大而增大,这与近地面钝体结流的机理不符。通过与欧洲规范EN 1991-1-4、美国规范ASCE 7-10、澳大利亚/新西兰规范AS/NZS 1170.2∶2011、加拿大规范NBC 2005、日本规范AIJ 2004等主要国外规范进行比较,发现主要国外规范仅给出了极值负压的最大值,而没有给出极值负压的分布。接着基于某项目风洞试验与中国规范GB 50009—2012的比较,发现高层建筑极值负压最大值一般发生在建筑中下部区域,并指出当前工程上采用的中国规范GB 50009—2012与风洞试验包络设计方法是不经济的。最后基于奥雅纳多年的风工程应用经验,对幕墙结构风荷载取值给出了一些建议,并特别强调风洞试验报告只有经独立于风洞试验单位的风专家审核后才可用于实际工程设计。张正维 杜平 Andrew Allsop 邹植 2017建筑结构2017,47,14:5
4Photonic gas sensors exploiting directly the optical properties of hybrid carbon nanotube localized surface plasmon structures显示文摘Weinvestigate the modification of the optical properties of carbon nanotubes(CNTs)resulting from a chemical reaction triggered by the presence of a specific compound(gaseous carbon dioxide(CO_(2)))and show this mechanism has important consequences for chemical sensing.CNTs have attracted significant research interest because they can be functionalized for a particular chemical,yielding a specific physical response which suggests many potential applications in the fields of nanotechnology and sensing.So far,however,utilizing their optical properties for this purpose has proven to be challenging.We demonstrate the use of localized surface plasmons generated on a nanostructured thin film,resembling a large array of nano-wires,to detect changes in the optical properties of the CNTs.Chemical selectivity is demonstrated using CO_(2) in gaseous form at room temperature.The demonstrated methodology results additionally in a new,electrically passive,optical sensing configuration that opens up the possibilities of using CNTs as sensors in hazardous/explosive environments.Thomas Allsop Raz Arif Ron Neal Kyriacos Kalli Vojtěch Kundrát Aleksey Rozhin Phil Culverhouse David J Webb 2016Light(Science & Applications)2016,5,1:3
