摘要
对高层建筑核筒式悬挂结构的动力特性进行了理论与振动台试验研究。推导了相应公式,编制了计算程序Hangsys;在模拟地震振动台上通过正弦波扫描和激振器激励对结构的自振特性进行了试验研究。理论计算和试验结果符合较好。结果表明,核筒悬挂结构具有较低的自振频率,具有良好的抗震性能。
Theoretical and shaking table test studies of the dynamic behavior of a core-wall suspension structures are performed. Formulas are given and a program Hangsys is developed using Matlab. Experimental results are obtained using sine wave scan and vibration exciter on shaking table. It is shown that the frequencies and modes are in satisfactory agreement between the analytical and experimental results. The first frequency of the suspension structure is much lower and the structure has better aseismic performance.
