摘要
采用一种基于光纤传感技术的新型缓粘结预应力智能钢绞线(S-RPS Ra3-12 15.20-1860)代替部分预应力钢绞线应用于第二炮兵文工团排演中心和总后礼堂工程大跨度预应力混凝土梁、板结构中,并简要阐述了S-RPS预应力损失监测与安全评估过程。
Based on the assessment need of long span prestressed concrete structures, a smart retard-bonded prestressed steel strand has been proposed by using the optical fiber sensing technology. It can be directly used in prestressed concrete beam and slab structures as the partial replacement of ordinary prestressed steel strands. Through prestress loss analysis, it can simply evaluate the safety of the structure, which has been val- idated in the project of the auditorium of the General Logistics Department and the rehearsal center of the Sec- ond Artillery Art Troupe.
