地震研究

对昆明16栋典型钢筋混凝土高层建筑物的振动特征(包括建筑物的固有频率、振型和阻尼比)进行观测与分析,对地震响应数值模拟研究,获取实测高层建筑物第一至第三振型及结构,计算第一至第二振型自振周期结果,采用数学线性回归方法,模拟得到昆明高(超高)层建筑结构实测第一至三振型和计算第一至第二振型周期公式,为类似建筑结构的设计提供经验和依据。

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.
