摘　　要：在大跨度和大悬挑结构设计中,为确保舒适度,需要进行舒适度验算。通过对江阴新国联大厦大悬挑钢-混凝土组合楼盖采用有限元时程分析,对2～5层和标准层楼盖分别建模,在平面不同位置,分别输入1人、3人、4人、8人同时跳跃荷载,分析位移响应峰值、速度响应峰值和加速度响应峰值。In the design of large span and large cantilever structure, the calculation of comfort is necessary to ensure the comfort. In the finite element time historyanalysisofthe large cantilever steel concrete composite floor of Jiangyin New Nation Building, the second to fifth floor and the standard floor stab are modeled respectively. At different positions of the plane, 1, 3, 4, 8 people are inputted respectivelyin the jumping load model and tested simultaneously. The peak ofdisplacement response, velocityresponse and acceleration response are analyzed.
