Based on the finite element analysis of the nonlinear shear deformation of the studs and the stress analysis of the partition
the shear deformation of the studs in two parts of the steel-concrete composite beam with box section is studied. The results show that the horizontal shear capacity of steel-concrete composite box girder is provided by web flange bolts. The installation of baffle flange bolts cannot improve the shear connection degree of composite beams. Removing the flange stud of the diaphragm can relieve the force on the diaphragm. The aboved conclusion provide a theoretical basis for reducing the stiffener of the diaphragm.
