摘要：

Currently there are only few research results for predicting the relationship between deflection and the crack mouth opening displacement (CMOD) of steel fibre reinforced concrete (SFRC) beams. A series of bending beam tests on SFRC, with different fibre contents and fibre types have been carried out. Based on the experimental results a model for predicting the relation between the deflection and CMOD of SFRC has been established. This model relies on the load-deflection relation and the load-CMOD relation of bending beam. A well agreement has been found between the suggested mode and the test results of other research. The results of this mode indicate that the load-deflection diagram is very similar to that of the load-CMOD diagram, and there is a linear relation between the mid-span deflection and CMOD of SFRC.
