摘要
沭阳体育场建筑造型优美,下部主体为钢筋混凝土结构,看台顶棚屋盖为钢结构,顶棚屋盖采用空间桁架结构体系,主桁架最大悬挑21.88m。针对其悬挑大、形状不规则的特点,文章详细阐述其结构布置,并利用有限元软件对屋盖结构进行受力、变形、模态和屈曲分析,探讨上下部结构协同工作对屋盖抗震性能的影响。
Shuyang Sports Center has a graceful architectural structure in interior part and steel structure on the roof. The appearance, which adopts reinforced concrete roof adopts large-span cantilever steel truss structure, with the main truss overhanging 21.88m. On basis of its large span and irregular shape,the system arrangement of this structure was laborated Through finite element analysis, the force,deformation,modality and buckling system of the roof structure were discussed.The effect of the synergistic work of the top and bottom structures to the seismic performance of the roof was discussed.
