WebSep 1, 2024 · Initially, the behavior of this model with one bolt is analyzed by comparing it with existing bibliography for 3 different types of applied load: tension, shear and a combination of these two. Web- Average shearing stress in the bolt = fv = P/A = P/(π db 2/4) - P is the load acting on an individual bolt - A is the area of the bolt and db is its diameter - Strength of the bolt = P = fv x (π db 2/4) where f v = shear yield stress = 0.6Fy - Bolts can be in single shear or double shear as shown below.
