摘　　要：以苏通大桥主塔#5墩钢吊箱为例,建立有限元模型,计算其频率和振型分布,并对哑铃形状钢吊箱结构进行地震作用下的响应谱分析,研究钢吊箱在地震情况下的响应特点,验证其安全可靠性。In this paper, in order to analyze the response of dumbbell-shape steel suspending cofferdam under seismic action, a steel suspending cofferdam of the largest frusta in Su-tong great bridge is taken as an example. A finite element mode is founded and the frequencies and modes are solved and a spectrum analysis is done. On the base of the solution, the response property of dumbbell - shape steel suspending cofferdarn under seismic action is researched and the safety is validated.
