摘要
纤维增强塑料(FRP)作为一种新型高性能的结构材料,具有轻质、高强和抗腐蚀等特点,在土木工程中是一种具有发展前景的新型预应力筋用材。采用应变折减的方法推导了体外预应力FRP筋混凝土梁承载力的计算方法,并将计算结果与试验数据进行了对比。研究结果表明本文推导的计算方法可以作为体外预应力FRP筋混凝土梁承载力的计算公式。
As a new structural material,FRP（fiber reinforced plastics） features light weight,high strength,corrosion resistance,etc.,and have a bright future when used for a new type of pre-stressing tendon in engineering structures.How to calculate the ultimate strength of external pre-stressed concrete beam with FRP tendons by means of strain reduction is introduced.Comparing with the test data,it indicates that satisfactory results may be obtained using the presented method.
