The article presents the results of stand tests and numerical analyses conducted in order to determine the working characteristic of a friction joint used in yielding supports and in friction props. A functional model was used to determine analytically the working of the friction joint. A stick-slip model of intermittent motion and a dry friction model were used to model the joint's yield capacity. The friction joint's working characteristic at axial compression and its yield capacity (i.e. joint tensile force) was determined as a result of the analysis. The results of friction joint stand tests at axial compression have also been presented in the paper and compared to the results of numerical analysis. The results obtained in stand tests and numerical analyses reveal high quantitative and qualitative consistency.
