When you select Calculated tensile stress area (Connector-Bolt PropertyManager), the program calculates the tensile stress area (At), which is the minimum area of the threaded section of the bolt, according to the formula: At = [(d3 + d2) / 2)]2 * π /4 P = pitch, axial distance...

The value for tensile stress area can be determined from: As = π/4 x (D - (.938194 x p))² Where: D: bolt diameter p: 1/threads per inch (TPI) Clamp load is typically around 75% of a bolt’s proof load; that is, the highest stress the bolt can accommodate before experienci...
However, a large number of strength tests has shown that in the case of standardized threads, the factual critical cross-sectional area is larger. This area is usually termed the "Tensile stress area" and its section corresponds to the arithmetic mean from the centre and small diameter of the...
@Chano- In a straight line pull, the length of the bolt is irrelevant. The breaking point is the tensile stress area multiplied by the minimum tensile in psi. If your joint is more complicated, and if there are forces that are not in a straight line, then you will need to consult an...
