摘要
上海环球金融中心工程采用整体钢平台模板体系,以结构体系的可靠度理论为基础,通过结构响应的泊松分布假设,分析得到了多自由度体系的动力可靠度的简化计算公式,以此得到整体钢平台模板体系动力可靠度的区间估计。研究结果表明,整体钢平台模板体系工作工况下的动力可靠度随着施工高度的增加而降低,相应的区间半径也逐渐增加。整体钢平台模板体系只能在6级风或6级以下风速时进行提升。
Integral steel platform formwork system （ISPFS） used in Shanghai Global Finance Center Project is a new kind of formwork system to adapt the construction need of super high buildings, which has a wide application prospect in China. Based on the reliability theory of structure system, a simplified formula of calculating dynamic reliability of multiple freedom-degree system was obtained by means of Poisson distribution hypothesis of structural response, and the dynamic reliability interval of ISPFS was estimated accordingly. Research results indicate that the dynamic reliability of ISPFS reduces along with the increasing of construction altitude, and the interval radius increases accordingly in case of working. On the other hand, the ISPFS can only be lifted under the condition of 6-grade wind or below.
