In order to solve the big error problem of depth measurements by a large span cableway, an automatic positioning type cable supporting equipment is equipped on cableway to reduce span or droop extent, so as to reduce depth measurement error.
为解决大跨度缆道测深误差偏大的问题,在缆道工作索上安装自动定位式支索器,以缩小跨度(垂度),减少测深误差。
Taking the structure of the gymnasium of Yellow River Hydrotechnical Vocational Institute as an example,this paper analyzes large-span arch-supported membrane structure using nonlinear finite element method and approaches to the characteristics of stressing and deformation of this kind of structure.
本文以黄河水利职业技术学院风雨球场拱支索膜屋盖为工程案例,采用非线性有限元法,对大跨空间拱支索膜结构体系进行了结构分析,探讨了拱-膜组合结构的受力和变形规律,检验了初步阶段膜找形结果的可靠性,为同类结构的工程设计提供经验积累。
