Through steel box girder grouting counterweight, the application of beam string structure had been realized in the coastal high pressure region under the action of wind suction. The layout of the structure and the roof system, analysis results of overall structure and cut pieces, key nodes design, finite element analysis results, support design, and construction simulation were introduced, especially the counterweight design principles of steel box girder, grouting scheme comparison and selection, box girder stiffened optimization analysis, specific implementation methods and measures of related construction, which can be a reference for structural design of similar projects.Keywords: roof structure; beam string structure; steel box girder; counterweight作者簡介：張同億，博士，教授級高級工程師，Email: zhangtongyi@ippr.net參考文獻［1］ 廈門國際會展中心二期結構專項審查告［R］.北京：中國中元國際工程公司,2009.［2］ 薛偉辰，劉晟，蘇旭霖，等.上海源深體育館預應力張弦梁優(yōu)化設計與試驗研究［J］.建筑結構學報,2008,29(1):16-23.［3］ 田煒，崔家春，李承銘,等.張弦梁關鍵問題研究［J］.建筑結構，2009,39(S1)：73-78.
