Combining with seismic response characteristic, three shock absorption methods were proposed including setting fluid viscous dampers between columns and joints of the roof, column cap seismic isolation and tuned mass damper. Feasibility study of the three damping methods for the seismic response of the hangar under earthquake input from different directions was carried out. The reduction effects of base shear, lateral displacement of column cap, inner force of space-frame poles and displacements of joints in the roof were compared and the advantages and disadvantages of every method were analyzed. The results show that passive control methods can effectively decrease the seismic response by setting shock absorbing device and parameters reasonably.Keywords: long-span maintenance hangar; seismic response; passive control; energy dissipation brace; column cap seismic isolation; tuned mass damper*國家自然科學(xué)基金面上項(xiàng)目(51178100),江蘇省自然科學(xué)基金面上項(xiàng)目(BK2011693)。作者簡介:徐慶陽,博士,講師, Email:05098414@163.com。參考文獻(xiàn)[1]沈順高. 大跨度機(jī)庫方案的概念設(shè)計(jì)與動(dòng)力性能研究[D]. 北京:清華大學(xué),2002.[2]曹資,薛素鐸. 空間結(jié)構(gòu)抗震理論與設(shè)計(jì)[M]. 北京:科學(xué)出版社,2006.[3]唐柏鑒. 大跨屋蓋結(jié)構(gòu)的抗震與減震研究[D]. 上海:同濟(jì)大學(xué),2006.[4]徐慶陽. 大跨機(jī)庫結(jié)構(gòu)減震分析與優(yōu)化研究[D]. 南京:東南大學(xué),2008.[5]SOONG T T, DARGUSH G F.
