［摘要］昆明滇池國際會展中心展館主序廳鋼屋蓋曲面由多種幾何形狀組成，空間造型復(fù)雜。介紹了主序廳鋼屋蓋的結(jié)構(gòu)體系，給出了鋼屋蓋結(jié)構(gòu)及其豎向承重結(jié)構(gòu)的布置方案；通過多種有限元軟件對主序廳進(jìn)行計算分析，給出了整體結(jié)構(gòu)的動力特性、結(jié)構(gòu)平面規(guī)則性及中庭柱的穩(wěn)定分析等主要計算結(jié)果；對樹形柱的關(guān)鍵部位進(jìn)行了補充分析，給出了通過配重及局部提高鋼材強度的方法來改善樹形柱受力性能的設(shè)計思路。［關(guān)鍵詞］穩(wěn)定分析; 彎扭構(gòu)件; 配重; 鋼屋蓋中圖分類號：TU393.3 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2015)14-0040-06
Structural design of main preface hall of Tien Lake International Conference Exhibition Center in KunmingZhu Qinghua（China Majesty Structure Design Office Co., Ltd., Shanghai 200135, China）Abstract: The steel roof of the main preface hall of Tien Lake International Conference Exhibition Center in Kunming has a complex space form which consists of multiple geometric shapes. The structural system of the steel roof for main preface hall was introduced, and structural layout schemes for the steel roof structure and its vertical bearing system were provided. The main calculation results were presented by analyses of various finite element programs, including dynamic characteristics of the whole structure, regularity of the structural plan and stability analyses of the atrium columns. Additional analyses of key regions of the atrium columns were provided and better design ideas were given to improve the mechanical performance which used methods of counterweight and increasing steel strength locally.Keywords: stability analysis; bending-torsion component; counterweight; steel roof
