摘要
某冰壶馆钢屋盖结构采用单层网壳加张弦梁的杂交体系,单层网壳与张弦梁共同受力,形成良好的空间传力体系.本文详细介绍了其钢屋盖的结构构成和受力特点,并对张弦梁的撑杆高度、拉索直径及拉索预张力的大小进行探讨,从而确定合理的结构布置形式.采用有限元软件对结构进行了静动力分析、极限承载力分析以及抗连续倒塌分析,对类似结构的设计提供有益的参考和借鉴.
A curling hall steel roof consists of single -layer lattice shells and beam strings which bear loads together and form a good spatial system .The composition and characters of the structure were described in detail.The strut height of the beam string , the diameter and the pre -tension of the cable were discussed , thus the proper structure layout was determined .Static analysis , dynamic analysis , ultimate capacity analysis and re-sist progressive collapse analysis on the structure were carried out with FEM software .It＇s useful for the design of similar structure .
