对柱承式混凝土煤仓结构进行模态分析,得到其振型和频率的特点。同时,基于土-结构相互作用,进行柱承式混凝土煤仓结构的地震反应时程分析,通过输入3种地震波(El Centro波、Taft波和人工波),分析得到不同工况下煤仓结构节点的位移时程和最大位移值,确定出结构的薄弱部位,为柱承式混凝土煤仓结构的抗震设计和鉴定提供参考。
The modal analysis of the column-supported concrete coal bunker structure is obtained, and its vibration mode and frequency characteristics are obtained. At the same time, based on the soil-structure interaction, seismic response analysis of column-supported concrete bunker structure is carried out. By inputting three types of seismic waves (El Centro wave, Taft wave and artificial wave), the coal bunker structure under different conditions Node displacement time and the maximum displacement value to determine the weak parts of the structure, which provides a reference for the seismic design and identification of the column-supported concrete bunker structure.
