摘　　要：对高层建筑核筒式悬挂结构的运动特性和地震反应的计算进行了理论推导,并编制了相应的悬挂结构计算程序Hangsys,同时提出了核筒悬挂结构前几个周期的简化计算公式.试验结果和理论计算结果符合较好.结果表明,核筒悬挂结构具有较低的自振频率和较小的地震反应,具有良好的抗震性能.The algorithm of dynamic characteristics and seismic responses of core wall suspension structure are derived and a computer program Hangsys is designed and written based on it. At the same time, a simplified calculating means about the basic frequencies of this structure is suggested. It remains in satisfactory agreement between the shaking table tests results with the theoretic results. It＇s shown that the basic frequency of the suspension structure is somewhat lower and this structure has better aseismic performance.
