摘要
通过 2 5根钢筋钢纤维混凝土梁的抗弯性能试验 ,研究了钢纤维和高强混凝土对受弯构件初裂强度、极限强度和延性的影响。
This paper presents an experimental study on 25 FRC beams.It is proved that main variable such as the steel fiber and the high strength concrete have great effects on the first cracking strength,the ultimate strength,the ductility of the FRC beams.The formula for calculating normal section strength of flexural HFRC beams is presented.
