跨度800m凯威特型巨型网格结构在8度多遇地震作用下受力性能分析
Mechanical performance analysis of 800 m span Kiewitt type mega-latticed structures under 8 degree frequent earthquake
摘要
Abstract
The mechanical performance of an 800 m span Kiewitt type mega-latticed structure under frequent earthquake action was researched.Based on the displacement and internal force weight,the Rayleigh damping coefficient calculation was modified.Furthermore,time-history method was adopted to analyze the 800 m span Kiewitt type mega-latticed structure under 8 degree frequent earthquake,and the influence of displacement and internal force response was made.The calculation results show that the amplification factor of the structure's maximum displacement and internal force ranges from 1.1 to 1.2.In addition,by comparing mode-interrupt and mode-filter mothed,the combined order determined by the latter has higher precision and higher computation efficiency.The calculation results of multi-dimensional response spectrum method and time-history method were compared.The average error of the displacement and internal force by using the two methods is around 10%,and the response envelope is roughly the same.关键词
