WebbSubstituting the appropriate values for a bolt M24 grade 10.9 gives the following result: Ft.Rb = = 254 kN For a constant amplitude fatigue loading at zero mean level containing more than 107cycles, the allowable maximum force on the bolt will be: Fmax= DF/2 = DsDAs/2 = 0,5 x 26 x 353 = 4,6 kN WebbThe study by Nair et al. (1974) into the effect of tension and prying forces found that the load capacity of bolted connections can be substantially reduced by prying action. The factors found to govern the magnitude of this prying force include the geometry and material properties of the end plate, and the size and strength of the bolts.

Webb11 sep. 2024 · Usually, the force which is acting in one of the legs gets transferred to the entire cross-section in the form of shear. At the location of the connection, the stress distribution is non-uniform due to the concentration of force on the connected leg. This "lag" in stress distribution in the tension member is termed as "SHEAR LAG".
