摘要
对《索结构技术规程》(JGJ 257-2012)局部修订的原则及主要内容进行了介绍.此次局部修订工作,尽可能全面反映国内外近 10 年来在索结构产品、设计、施工等方面新成果、新经验,主要梳理、变更、完善的内容包括索体材料的分类、屋盖挠度允许值及其计算点对应的荷载、张拉控制原则及指标、柔性索承载力设计值确定基准、节点承载力要求、索结构监测及关于劲性索的规定等.最后,对后续工作进行了展望.
Abstract
The principles and main contents of the partial revision of Technical specification for cable structures(JGJ 257-2012)were introduced.This partial revision work reflects the new achievements and new experience in cable structure products,design and construction in the past 10 years at home and abroad as much as possible.The main contents of combing,changing and perfecting include the classification of cable material,the allowable value of roof deflection and the corresponding load of calculation point,the principle and index of tension control,the design value of flexible cable bearing capacity,the requirement of joint bearing capacity,the monitoring of cable structure and the provisions on rigid cable.Finally,the future work was prospected.
