摘要：

A total of nine beams have been tested to investigate the influence of fibre reinforcement on the mechanical behaviour of reinforced concrete beams in shear. The major test variables are the volume fraction of steel fibres and the ratios of stirrups to the required shear reinforcement. The test results show that the first crack shear strength increases significantly as fibre content increases and the improvement in ultimate shear strength is also achieved. The present study indicates that fibre reinforcement can reduce the amount of shear stirrups required and that the combination of fibres and stirrups may meet strength and ductility requirements. An analytical method to predict the shear strength of reinforced concrete beams containing steel fibres is proposed and comparisons made with the present test data as well as other data.
