尿素造粒塔在风荷载作用下的结构反应分析

ANALYSIS OF UREA PRILLING TOWER UNDER WIND LOADS

采用有限元软件SAP2000研究尿素造粒塔在风荷载作用下塔底内力变化情况;分析风荷载作用下结构物的变形情况;分析风荷载下结构物的响应情况及不同基本风压下外壁的主应力分布情况。得出下述结论:在风荷载作用下,造粒塔塔底内力、位移以及应力变化都与基本风压成线性关系。

In this thesis, using the finite element software SAP2000,it studied the change of the internal forces of urea prilling tower foundation under different wind loads, it analyzed the structure deformation under wind loads, it also analyzed the structure responses under wind loads and the main stress distribution of the outer wall under different wind pressure. Summing up that, under wind loads, the bottom internal forces of the tower, displacement and stress changes all had linear relationship with the basic wind pressure.
