1/5 Scale Reinforced Concrete Bare Frame with Deficient Seismic Detailing, Frame 1

First frame was constructed without partition walls and deficient reinforcement detailing. Deficiency was controlled by inappropriate longitudinal/transverse reinforcement detailing and also by insufficient splice length for longitudinal column reinforcement. During the static test of first frame, first story inter-story drift ratio reached to 0.7%, 1.1%, 1.5%, 1.9% levels and at the end of each cyclic loading frame is excited with an impact hammer for the purpose of modal analysis.首榀试验框架未设置隔墙，且存在钢筋构造缺陷。该缺陷源自不恰当的纵向与横向钢筋构造细节，以及纵向柱钢筋搭接长度不足。在首榀框架的静力试验过程中，首层层间位移角依次达到0.7%、1.1%、1.5%及1.9%；每一轮循环加载结束后，均采用冲击锤对框架进行激振，以开展模态分析。
