摘要

In order to recognize the behavior of joints joined by means of special blind bolts, in thin-walled structures, the author has tried to solve this problem analytically in connection with an experimental verification of exemplary calculations. Basing on his own investigations he has set up a regression curve for one single blind bolt, describing the relation between load and displacement. The regression function was introduced into a set of equations, which permits to calculate any arbitrary five-blind-bolt joint, simultaneously loaded with the bending moment and the shearing force. The results of numerical calculations were checked experimentally. By means of the suggested set of equations the interactive influence of the shearing force on the load-bearing capacity and rigidity of the investigated joint has been illustrated. Besides that, boundary curve of the load-bearing capacity of the joint has been plotted.
