In order to probe into the shear resistant behaviors ofsteel reinforced concrete(SRC)restrained beams

three test beams underconcentrated loads have been tested.A full range analysis of the testbeams is conducted by using nonlinear finite element(NLFE)techique

and a good agreement with the experimental results is achieved.Theshear resistant mechanism of SRC restrained beam and the main factorsaffecting its shear strength are analysed.It is found that when theavailable shear strength formula for simply supported SRC beams is usedto calculate the shear strength of SRC restrained beams

the result turnsout to be conservative

so it is suggested that the shear strength of SRCrestrained beam could be calculated by the corresponding formula ofsimply supported SRC beam

adopting calculation shear span ratio.Thepractical formula is proposed in the paper.
