［摘要］援塞內(nèi)加爾競(jìng)技摔跤場(chǎng)鋼罩棚為210m大跨空間拱結(jié)構(gòu)，由主拱、后拱及次桁架組成，介紹了結(jié)構(gòu)方案選型、結(jié)構(gòu)靜力、穩(wěn)定及拱腳節(jié)點(diǎn)分析。結(jié)果表明，主拱采用菱形截面，后拱及次桁架采用倒三角空間立體桁架，以及縱向次桁架、聯(lián)系桁架、支撐布置是合理的，桿件截面受力均勻，節(jié)點(diǎn)構(gòu)造簡(jiǎn)單，結(jié)構(gòu)空間整體性強(qiáng)；采用萬(wàn)向球鉸支座的主拱拱腳節(jié)點(diǎn)設(shè)計(jì)合理，能夠滿足設(shè)計(jì)要求。

Abstract:The steel shed of wrestling stadium aid for Senegal is a 210m large-span spatial steel arch structure that composed of the main arch, rear arch and the sub truss. Structural system selection, structural static analysis, stability and arch foot joint analysis were introduced. The analysis result shows that it′s rational to adopt diamond section in the arch structure, to adopt inverted triangular spatial truss in rear truss and sub truss and to adopt vertical sub truss, linking truss and support arrangement. The cross section of the rod has uniform mechanism, and joint structure is simple and spatial integrity of structure is strong. It′s rational to adopt the universal ball hinged support in the design of the main arch foot joint, and it can meet the design requirements.

Keywords:wrestling stadium aid for Senegal; large-span spatial steel structure； arch truss； static analysis； stability analysis； joint analysis
