摘要
通过两榀小比例部分预应力混凝土 (以下称简PPC)框架模型的振动台试验 ,研究预应力混凝土框架结构在地震作用下的动力特性和地震反应 ,主要包括自振周期 (频率 )、阻尼比、振型以及地震加速度反应等。并与相应的普通钢筋混凝土 (以下简称RC)框架模型振动台试验结果进行比较。
In this paper,based on the experiments of two small\|scale PPC frame models carried out on the shaking table,the dynamic properties and seismic response of prestressed concrete frames under the seismic action,inculuding their vibration period (frequency),damping ratios,vibration modes and their seismic acceleration responses ,are respectively investigated.Meanwhile,these properties are compared with those of one corresponding RC frame model.
