In order to simulate the whole structure stiffness and the natural vibration characteristics of the structure, the concrete stand and steel canopy were analyzed as a whole spatial structure. Based on the engineering practice, key problems in structural design were introduced, including the form of roof canopy support for the main truss, optimization of member section and decrease the cantilevered end deflection through exerting pre-stress, anti-collapse analysis through assuming the failure of pull rods between the main truss and columns. By using finite element software, the static nonlinear analysis, elastic response spectrum analysis, elastic time-history analysis and buckling modal analysis were carried out to verify the security, stability and rationality of the structure.Keywords: cantilever truss; pre-stress; anti-collapse analysis作者簡介：馮莉梅，高級工程師，Email:rd70710@vip.sina.com。參考文獻［1］劉志偉，張曉新．錦州濱海體育中心體育場結(jié)構(gòu)設(shè)計［J］．建筑結(jié)構(gòu)，2013，43（9）：29-32.［2］馬克儉，肖建春，劉晨，等．貴陽奧體中心體育場挑篷預應(yīng)力設(shè)計建議［J］．貴州工業(yè)大學學報：自然科學版，2008，37（4）：1-5.［3］陳志華，肖驍，劉紅波. 太陽輻射作用下鋼管溫度計算簡化方法［J］．天津大學學報：自然科學與工程技術(shù)版，2014，47（增刊）：1-7.［4］王紅濤，徐珂，田立強．某體育場罩篷鋼結(jié)構(gòu)設(shè)計［J］．鋼結(jié)構(gòu)，2012，27（6）32-36.［5］傅學怡，楊想兵，高穎，等．濟南奧體中心體育場結(jié)構(gòu)設(shè)計［J］．空間結(jié)構(gòu)，2009，15（1）：11-19.［6］陳肇元，錢稼茹．建筑與工程結(jié)構(gòu)抗倒塌分析與設(shè)計 ［M］．北京：中國建筑工業(yè)出版社，2010.
