The roof supporting system consists of two structural forms of tree and Y shape column, and folded plate space truss is used for roof. The choice of structure styles was introduced, the loads value and analytical results were given, and indepth analysis on some key issues in structure design was carried out. Based on the elastic-plastic analysis, the seismic performance of the structure was fully studied, and the effective length factor of the columns and the node design were introduced.Keywords: folded plate space truss; tree column; effective length factor; elastic-plastic analysis; seismic performance作者簡介:李云,碩士,工程師,一級注冊結(jié)構(gòu)工程師,Email: liyun@ippr.net參考文獻[1]JGJ 7—2010 空間網(wǎng)格結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京: 中國建筑工業(yè)出版社,2010.[2]董石麟,羅堯治,趙陽, 等.新型空間結(jié)構(gòu)分析、設(shè)計與施工[M]. 北京: 人民交通出版社,2006.[3]石家莊國際會展中心風(fēng)荷載及風(fēng)振研究報告[R]. 石家莊:石家莊鐵道大學(xué)風(fēng)工程研究中心,2012.[4]GB 50011—2010 建筑抗震設(shè)計規(guī)范[S]. 北京: 中國建筑工業(yè)出版社, 2010.[5]童根樹. 鋼結(jié)構(gòu)的平面內(nèi)穩(wěn)定[M]. 北京: 中國建筑工業(yè)出版社, 2005.[6]Federal Emergency Management Agency.
