For a bolted assembly with six bolts, the stiffness of each bolt is k_b = 3 Mlbf/in and the stiffness of the members is k_m 12 Mlbf/in per bolt. An external load of 80 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use 1/2 in-13 UNC grade 8 bolts with rolled threads. Assume the connection is not meant to be permanent. Determine the yielding (permanent set) factor of safety. Determine the overload factor of safety. Determine the factor of safety based on joint separation. If the external load is a repeated load, Determine the fatigue factor of safety for the bolts using the following failure criteria: Goodman. ASME-elliptic

Solution

The answer of following question is as follows.

The value of overload factor of saftey is 7 .
