摘　　要：整体悬吊式钢内筒烟囱,其内筒荷载由悬吊点、止晃点等全部传递给外筒,结构受力体系与单筒式烟囱或自立套筒式烟囱差别较大.采用有限单元法,分别计算烟囱分体模型和耦合模型的动力特征和地震效应,研究了水平及竖向地震作用对全悬吊式排烟筒烟囱的影响,并进一步提出在今后设计中应考虑的事项.The chimney with entire suspension inner steel tube is characterized by the more obvious coupling effects between concrete windshield and steel inner tube.In order to fully understand such characteristics,this paper calculates the dynamic characteristics and seismic action on it by using finite element method.Furthermore,some items that shall be taken into consideration in later design procedure are put forward.
