In the end plate connection, the arrangement of the stiffeners has a major influence on the force distribution of the bolts, and the stiffening ribs increase the bending stiffness of the end plates or column flanges, so that the bolts near the stiffeners can share a larger load. Stiffeners or beams are generally more resistant to lower bolts than the bolts on them, provided that the joints undergo some deformation to increase their load bearing capacity. For some connections where the bolt diameter is small and the end plate or column flange plate is relatively thick, the deformation ability is very poor. In this case, it is possible that the resistance of the lower row bolt has not been fully exerted, and the upper row of bolts is already Destruction, in order to avoid this, ensure that the bolt is subjected to force plastic distribution, and the thickness of the end plate or column flange plate should be limited. If the thickness of the end plate or column flange plate exceeds this limit, the force distribution of the bolt It must be corrected that the bolt force should not exceed the triangle distribution. When the bolt force exceeds the triangle distribution, it must be reduced. The remaining reaction force can be borne by the lower row of bolts. Unlike the traditional method, the plasticity of the bolt is forced. The distribution is closer to the actual stress situation and is experimentally verified. Although this method is more complicated, the calculation is more accurate and provides higher bending resistance and prevents premature failure of the bolt. The bearing capacity of the tension zone is checked. The resistance of the bolt is calculated. The resistance of the bolt should be calculated row by row. Starting from the outermost row of bolts in the tension zone, it is carried out from top to bottom. When calculating the current row of bolts, the lower bolts are calculated. They are all ignored. When interacting with the upper row of bolts, the resistance of the current row of bolts is the resistance of all bolts participating in the combination minus the resistance of the corresponding upper row of bolts.
The calculation procedure for bolt resistance. If the end plate thickness tp>d1.9UfPyp and the column flange thickness Tc>d1.9UfPyc, the force distribution of the bolt should be corrected. Where d is the bolt diameter; pyp is the design strength of the end plate; pyc is the design strength of the column; Uf is the ultimate tensile strength of the bolt. Bending capacity calculation The actual force of the bolt should meet the force balance condition and not greater than its possible resistance. EFri+N=Fc and Fri
