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作者简介：张同亿，博士，教授级高级工程师，Email: zhangtongyi@ippr.net参考文献［1］ 厦门国际会展中心二期结构专项审查告［R］.北京：中国中元国际工程公司,2009.［2］ 薛伟辰，刘晟，苏旭霖，等.上海源深体育馆预应力张弦梁优化设计与试验研究［J］.建筑结构学报,2008,29(1):16-23.［3］ 田炜，崔家春，李承铭,等.张弦梁关键问题研究［J］.建筑结构，2009,39(S1)：73-78.
