(1 北京市建筑設(shè)計研究院,北京 100045; 2 北京交通大學(xué),北京 100044)[摘要]針對廣州新客站站橋合一的特點,分析了高速列車通過時其振動對候車室舒適度的影響,同時對候車室大跨鋼桁架樓蓋在人行荷載下的舒適度進行了分析研究。結(jié)果表明,高速列車通過時,候車室的振動峰值加速度介于商業(yè)建筑與人行天橋之間,大跨度樓蓋在人行荷載下的峰值加速度可以滿足舒適度要求。[關(guān)鍵詞]廣州新客站;振動舒適度;減振;鋼結(jié)構(gòu)Study of vibration comfort of a bridge-station combined railway stationSheng Ping1, Wang Yi1, Zhang Nan2, Zhen Wei1(1 Beijing Institute of Architectural Design, Beijing 100045, China; 2 Beijing Jiaotong University, Beijing 100044,China)Abstract:The dynamic responses of the train-bridge-station system of New Guangzhou Railway Station is studied when the train goes through with high speed. The effect factor and distribution of vibration comfort rules of large-span truss floor are analyzed. It is shown that the vibration frequency and peak acceleration satisfy the vibration comfort standard.Keywords:New Guangzhou Railway Station; vibration comfort; vibration decreasing; steel structure作者簡介:盛平,碩士,教授級高工,Email:Shengp@biad.com.cn。參考文獻[1]盛平,柯長華,甄偉,等.廣州新客站結(jié)構(gòu)總體設(shè)計[J].建筑結(jié)構(gòu),2009,39(12).[2]徐培福,傅學(xué)怡,王翠坤,等. 復(fù)雜高層建筑結(jié)構(gòu)設(shè)計[M]. 北京: 中國建筑工業(yè)出版社, 2005.[3]MIDAS技術(shù)手冊:結(jié)構(gòu)分析與設(shè)計[M].北京邁達(dá)斯技術(shù)有限公司,2002.[4]宋志剛,金偉良. 行走激勵下大跨度樓板振動的最大加速度響應(yīng)譜方法[J]. 建筑結(jié)構(gòu)學(xué)報,2004(4).[5]朱鳴,張志強,等.大跨度鋼結(jié)構(gòu)樓蓋豎向振動舒適度的研究[J].建筑結(jié)構(gòu),2008,38(1).[6]ALLEN D E, RAINER J H.Vibration criteria for long-span floors[J].
