Theoretical Study on the Tensile Strength of the New Type Single Side Full Bolt Connection

It's easy to connect the square steel tube and H-shape steel beam with the new type full bolt joints. Different connections, different tension resisting capacities. Experimental study found that the tensile strength of the new type single side full bolt connection depends on the thickness of the plate, the type of steel, the rigidity of the steel sheet and so on. By using the related knowledge of elastic mechanics, It is obtained approximation formula of elastic thin plate at any point in the elastic deflection stage under the new type single side full bolt connection, in which welding attaching plate acted as a nut and screw worked as a concentrated force. the flex value of the corresponding point can be drawn through the formula, and the actual measurement value can be gained with the test of 6 groups of specimen in the same axial tension test. The result indicates that the approximate theoretical derivation value and the actual measured value are approximately equal, verifying the correctness of the proposed formula.
