通过一榀多层单跨有粘结预应力混凝土框架在低周反复水平荷载下的拟静力试验,进行了预应力混凝土框架的破坏形态、位移延性、刚度退化、耗能能力等抗震性能的研究。结果表明,经合理设计的预应力混凝土框架能依次形成多个塑性铰,结构具有较好的延性和耗能能力,锚具具有较好的工作性能,分析结果为预应力混凝土框架在地震区的工业应用提供参考。
Through the pseudo-static test of a single-span multi-span single-span bonded prestressed concrete frame at low cyclic repeated horizontal loads, the failure modes, displacement ductility, stiffness degradation, energy dissipation capacity and other seismic performance of prestressed concrete frames the study. The results show that the rational design of prestressed concrete frame can form multiple plastic hinges in sequence, the structure has good ductility and energy dissipation capacity, and the anchorage has better working performance. The analysis result shows that the prestressed concrete frame is located in the seismic zone Industrial applications for reference.
