钢筋混凝土框架结构动力特性研究
|
摘要
本文利用SVSA结构振动信号采集分析系统,对31幢钢筋混凝土框架结构的动力特性进行了现场实测,统计分析结构在环境随机振动作用下的动力特性规律。回归得到了自振周期与房屋层数、高宽比的关系,阻尼比与房屋高度、自振频率之间的关系,可供工程设计参考。
The authors performed the dynamic characteristic test of 31 reinforced concrete(RC) frame structures on the site by using SVSA (The System of Vibration Signal Acquisition and Analysis). Under ambient excitation, the rule of the dynamic characteristics of the structures is analyzed on the basis of the statistical data. Some useful engineering design relationship, e.g. natural period versus building storeys or height-width ratio, damping ratio versus building height or natural frequency can be established by previous regressive analysis.
