The double C steel section is made of two C steels with gusset plate through bolts. A ridge joint of double C steel is studied through experiment under cyclic loading in this paper. Through the four specimens with different gusset-plate’s thickness and bolt spacing, we analyze the effect of the gusset-plate’s thickness and bolt spacing on stiffness, ductility and energy performance. At last we recommend the suitable gusset-plate’s thickness. The results can give a reference to the engineering application of cold-formed steel structure.

This work presents an experimental study on the flexural behavior of steel tube slab composite beams subjected to pure bending. The main design elements considered in the work are the flange thickness, reinforcement ratio of high strength bolts, spacing between the tubes, and transverse patterns of the tube connections. Based on nine flexural experiments on simply supported steel tube slab specimens, the failure process and crack development in steel tube slab specimens, and their load–deflection curves are investigated. The results of the laboratory tests show that the welding of the bottom flange significantly improves the flexural capacity of the steel tube slab structure. In addition, a lower concrete’s compressive strength improves the ductility of the steel tube slab specimens. Moreover, the flexural capacities predicted from the design guidelines are in good agreement with the experimental test results. Finally, based on the numerical simulations using the ABAQUS software, a numerical model is established to further investigate the effect of the additional parameters on the flexural capacity of steel tube slab structures. The numerical results suggested that the diameter of the steel bolts and the reinforcement ratio have a limited effect on the flexural bearing capacity of the steel tube slab beams, and the ultimate bearing capacity increases linearly along with increase in the diameter of the steel bolts and the reinforcement ratio in a certain range.

Shear Strain Curve

This study examines the shear behaviors of concrete structure with recycled concrete and artificial sand (AS). Thirty-six beams were prepared with two strength grades (C35, C45) and different artificial sand replacement rates (0%, 30%, 50%, 70%, and 100%). They were submitted to four-point static stress test in order to distinguish the shear behaviors of ASCRC (AS-containing recycled concrete) and of natural concrete that is fabricated using original coarse aggregate and natural sand. Experimental results found the shear strengths values of the ASCRC were lower than the nature ones, with decreasing extents less than 20%. When AS-containing level ranged from 30% to 70%, the cube compressive and shear strengths were more lower than other replacement ratios. Shear force-shear strain curve of the ASCRC was found similar to that of the nature concrete. The peak strain of the ASCRC rose with the increase of the shear strength, but the slope of the curves was lower.
