摘要
针对郑州国际会展中心展厅钢屋盖的施工阶段需要,将跨中预应力索拱构件单独建模,运用ANSYS对其预应力施加前后的受力性能进行分析,探索劲性格构拱、竖向腹杆和下悬预应力张拉索的内力分布特征,可供工程设计与施工参考。
The pre-stressed cable arch is independently taken and its numerical model is established to analyze the construction behaviors of the steel roof of Zhengzhou International Convention and Exhibition Center. The behaviors of structures before and alter pre-stressing are analyzed by ANSYS software. The characteristics of the internal forces of the steel arch-truss, struts and prestressed cable are also explored, which may be a reference for design and construction of projects.
