摘要: 安阳文体中心全民健身及游泳馆是安阳市文体中心重要的场馆之一，共设看台座席 1 500 余座。建筑主体采用钢筋混凝土框架结构，屋盖采用钢管桁架结构。梳理了建筑条件、抗震设防要求，明确了荷载取值，并选取合理的结构体系；本工程为特别不规则结构，设计借鉴超限高层的相关要求，采用了多种结构计算程序对结构整体进行多遇地震下振型分解反应谱法、弹性时程分析补充计算以及罕遇地震下结构弹塑性分析；并采取了综合性的加强措施，达到了结构抗震性能化设计的预期目标。

Abstract: The Fitness and Natatorium is an important venue of Anyang Cultural and Sports Center which has more than1 500 seats. The building adopts concrete frame structure,and the roof is pipe truss steel structure. The architectureconstruction,seismic fortification requirements were sorted out,determination of loads was explicted and a reasonablestructural system was selected. This project was a particularly irregular structure,and the related design requirements of theout-of-code high-rise buildings were used for reference. A variety of structural calculation programs were used to carry outthe modal decomposition reaction spectrum method under frequent earthquakes,the supplementary calculation of elastictime-history analysis and the elastoplastic analysis of the structure under rare earthquakes. Comprehensive strengtheningmeasures were taken to achieve the expected goals of seismic performance design.

Keywords:Anyang Cultural and Sports Center； large-span roof； particularly irregular structure； elastoplastic time-historyanalysis； special demonstration of seismic design
