摘　　要： 广州亚运城体操馆钢结构屋盖施工难度大,为确保施工安全,采用有限元软件MIDAS对屋盖钢结构体系的安装过程进行了模拟分析,并使用精密仪器设备对屋盖结构的应力和变形情况进行了监测。通过有限元计算值和现场实测数据的比较,找出了结构受力和变形的规律,并查找了实测数据与计算值存在差异的原因,为评估体操馆的施工安全提供了依据。 The construction of gymnastic hall steel structure roof in Guangzhou Asian Games Town is difficult. To ensure construction safety, the finite element software MIDAS is adopted to simulate and analyze the installation process of the steel structure roof system, and precise instruments and equipments are used to monitor the stress and deformation of the roof structure. By comparing the calculated value by finite element software and measure data on the spot, the characteristic of stress distribution and displacement of the steel roof was found; reasons for the differences between the calculated value and measured value is found. These results provide basis for the evaluation of construction safety of gymnastic hall and significant references for the construction of similar projects in the future.
