城市高架叠跨段组合型模板支架稳定性分析
Stability of combined formwork bracket of urban elevated bridge overlapping section
摘要
Abstract
In order to evaluate the overall stability of cast-in-place box girder formwork bracket,the composite scaffolds of Zhongzhou Avenue and north tricyclic cross-overlap segment in Zhengzhou Sanhuan elevated rapid project were selected as the research object,and midas civil was used for finite element analysis.The analysis results show that the overall stability of the support bracket of West Amplitude Bridge is the lowest,but the o-verall stability coefficient still reaches 2.48.The overall stability of the formwork support is greatly affected by the section size and step length of the steel pipe.It is recommended that the unqualified rod be rejected before inspection.When the step size increases from the original design 800mm to 1200mm,the overall stability fac-tor of the bracket can still be guaranteed to reach 2.21.关键词
