| Abstract: | Having observed and analyzed the vibration characteristics(including inherent frequency,mode and damping ratio)of 16 typical reinforced concrete high-rise buildings in Kunming,and studied the numerical simulation of the seismic response,we obtain Vibration Mode 1-3 and structure of high-rise buildings,and calculate the natural vibration period of Vibration Mode 1-2.Using linear regression methods,we obtain the stimulant formula of the actual measuring of Vibration Mode 1-3 and the theoretical calculating of Vibration Mode 1-2 of high-rise(skyscraper)buildings in Kunming by simulation,which provides experience and basis for the design of similar building structure. |
