摘要
作为一种新型建筑材料,FRP具有轻质、高强、耐腐蚀等优点,非常适合作为预应力筋材料.通过4根预应力FRP筋混凝土梁在低周反复荷载下的试验研究,根据预应力FRP筋混凝土梁在低周反复荷载下滞回曲线的特点,提出了适合于预应力FRP筋混凝土梁的弯矩-曲率恢复力模型,并与试验结果进行了比较,计算模型与试验结果吻合良好。
As a new structural material,fiber reinforced plastics（FRP） features light weight,high strength,corrosion resistance,etc.,and has a bright future when used for a new type of prestressing tendon in engineering structures.The pseudo-static test on four concrete beams under low reversed cyclic loading is introduced in this paper.Based on the characteristic of measured hysteresis curves of concrete beams prestressed with FRP tendons,a new moment-curvature hysteresis model is proposed,which agrees well with experimental curves.
