英文摘要	The shear performance of 8 concrete filled rectangular steel tubular members without end-plate was tested. The influences of the section size and shear-span ratio (0.3-0.8) on shear capacity and slip behavior were studied. The result indicates that the specimens experience shear failure when the shear-span ratio is 0.3. With the increasing of shear-span ratio, the failure pattern of the specimens changes from shear failure to bending failure, the shear capacity decreases, and the slip of core concrete decreases. The numerical simulation was carried out using ABAQUS, and the calculating results agree well with the test results in general. The model was verified by the tested results. The influences of parameters such as friction and bonding, with or without end-plate and different axial loading were investigated on the shear performance of the specimens. The results show that calculating results agree well with the test results when the friction coefficient is 0.25 in finite element model. The end-plate has a small effect on the yield platform of load-displacement curves, but it has a great effect on the strength of load-displacement curves. The axial load affects the shear capacity significantly. © 2018, Engineering Mechanics Press. All right reserved.
