摘要
宽7 m、长1000 m的螺旋环道通过悬挑钢板连接件与32颗斜柱偏心连接成一倒锥体螺旋结构,结构体系新颖。基于结构特点,对螺旋环道活荷载分布、规避第一周期扭转的措施、螺旋环道人行舒适度、悬挑钢板与斜柱的节点、柱脚节点等进行分析并有针对性地采取了加强措施。结果表明结构具有良好刚度和强度,满足规范各项指标要求,保证了工程的安全性、合理性。
The helical walkway with a width of 7 m and a length of 1000 m is eccentrically connected with 32 inclined columns through a cantilevered steel plate connector to form an inverted cone helical structure.The structure system is novel.Based on the structural characteristics,analysis was carried out on the walkway live load distribution,measures to avoid the first modal of torsion,walking comfort of the walkway,the joints of the cantilevered steel plate and the inclined column,column foot joints.Take targeted measures to strengthen.The results show that the structure has good rigidity and strength,and meets the requirements of the specifications.The safety and rationality of the project were ensured.
