摘要
通过配有曲线无粘结预应力筋的框架自由振动试验 ,对时程曲线进行分析 ,计算了结构处于塑性铰阶段曲线预应力筋一个周期内的耗能效应。
Upon the test of the free vibration of a frame with unbonded curve prestressing tendons,energy dissipation effects within a period of vibration in stage with plastic hinges are calculated by analyzing its time history curve in this paper.
