尿素造粒塔在水平地震作用下的结构反应分析

ANALYSIS OF UREA PRILLING TOWER UNDER HORIZONTAL EARTHQUAKE ACTIONS

采用有限元软件SAP2000研究尿素造粒塔在水平地震作用下随着地震烈度的改变塔底内力的变化情况、塔的动力特性和变形情况及截面的应力变化趋势,得出下述结论:在水平地震作用下,结构的塔底内力、位移以及应力变化都与各地震烈度下水平地震影响系数最大值成线性关系。

In this thesis, using the finite element software SAP2000, it studied the change of the internal forces of urea prilling tower foundation,the dynamic characteristics and deformation of the tower, and the stress changes under the horizontal earthquake loads with different earthquake intensity, and got the following conclusions： in the horizontal earthquake, the internal force of the bottom structure, displacement and stress changes all have a linear relationship with the maximum factors affecting the level of earthquake under different earthquake intensity.
