［摘要］蘇州國際教育園體育中心為平面及豎向特別不規(guī)則的結(jié)構(gòu)，其中籃球館為大跨度屋面，采用型鋼混凝土柱+管桁架為主要受力構(gòu)件的輕鋼屋面體系。采用一端固定支座、一端帶滑動(dòng)支座的管型材三角空腹鋼桁架，充分發(fā)揮空間桁架優(yōu)勢，不僅滿足建筑立面效果和凈高要求，而且釋放溫度應(yīng)力；對建筑要求的大外挑立面，也提出相應(yīng)的結(jié)構(gòu)對策；對主體結(jié)構(gòu)的總裝模型，通過多軟件的比較分析、彈性時(shí)程分析、靜力彈塑性分析、對關(guān)鍵構(gòu)件進(jìn)行抗震性能化設(shè)計(jì)及采取相應(yīng)抗震措施后的結(jié)果表明，結(jié)構(gòu)具有充分的抗震能力。

Abstract: Suzhou International Education Park Sports Center is a structure with especially irregular plane and elevation. For large span roof of basketball arena, light steel roof system was adopted with steel reinforced concrete columns and tube trusses as the main components. Because adopting fixed bearing and sliding bearing on the two ends, triangle hollow steel truss with tube sections takes the advantage of spatial truss in fulfilling facade effects, clear height requirements and releasing the thermal stress. Corresponding structural design method was provided for large cantilevered facade. Through comparing analysis of different programs, elastic time-history analysis, static elastic-plastic analysis, seismic performance-based design of critical components and corresponding strengthened measures of the whole model, the seismic performance of the structure was ensured.
Keywords: particularly irregular; large cantilevered structure; large span; tube truss; sliding bearing
