强震作用下液压爬模抗震性能分析
|
摘要
以昆明西山万达广场核心筒施工中所用液压爬模为工程背景,利用ANSYS建立有限元模型,研究施工状态和爬升状态时爬模在3条不同三向地震波作用下的时程响应。研究发现,爬架在不同地震波作用下地震反应有明显差别;爬架在不同工况下的最大位移由不同方向的地震波控制;施工状态时,爬架上架体位移和等效应力均较大;爬升状态时,三角架横梁与导轨连接处出现最大等效应力。
Based on the hydraulic climbing formwork used in the construction of the core tube of Kunming Xishan Wanda Plaza,the finite element model is established by ANSYS to study the time history response of climbing formwork under three different three-dimensional seismic waves in construction and climbing conditions. It is found that the seismic response of the climbing formwork under different seismic waves is obviously different. The maximum displacement of the climbing formwork under different working conditions is controlled by seismic waves in different directions. The displacement and equivalent stress of the upper frame of climbing formwork are larger in the construction state. The maximum equivalent stress occurs at the joint of the triangle beam and the guide rail in the climbing state.
