摘要: 浙江省黃龍體育中心主體育場為承擔(dān)亞運功能的重要體育建筑,為滿足亞運會足球賽事的各項要求,對其進行整體更新改造。 介紹了主體育場更新改造的總體思路并進行了抗震性能化分析,分析結(jié)果表明,主體結(jié)構(gòu)能滿足抗震設(shè)防烈度 7 度、設(shè)計使用年限 30 年的抗震性能要求;采用頻率振動法實測了斜拉索的索力,結(jié)果表明索力都有一定程度的損失。 按實際索力對鋼屋蓋進行分析,分析結(jié)果表明目前的索力損失不影響結(jié)構(gòu)安全;對屋面板翻新改造過程進行受力分析和施工監(jiān)測,分析結(jié)果表明屋面結(jié)構(gòu)受力與變形均在容許范圍之內(nèi),可以滿足各項要求。

Abstract: The main stadium of Zhejiang Huanglong Sports Center is an important sports building to undertake the functionsof the Asian Games. In order to meet the requirements of the Asian Games football matches, reconstruction of overallstructure has been achieved. The overall idea of reconstruction of main stadium was introduced, and the analysis of seismicperformance was achieved. The analysis results show that the overall structure can meets the seismic performancerequirements of seismic fortification intensity of 7 degrees and design service of 30 years. The cable forces of stay cableswere measured by frequency vibration method, and the results show that the cable forces are reduced. According to theactual cable force, the steel roof was analyzed. The analysis results show that the current cable force attenuation does notaffect the structural safety. The stress analysis and construction monitoring were carried out during the renovation of the roofslab. The analysis results show that the stress and deformation of the roof structure are within the allowable range, whichcan meet various requirement.
