Design for Fatigue of Structural Steel - The C&S Companies
What is the design stress range for a ¾” dia. A325 bolt that is loaded 300,000 times cyclically? The bolt takes up to 5 kips in tension (3 kips from direct tension and 2 kips from moment) Is the bolt OK? Recall that F. SR = 1000 x (C. f / n. SR) 0.333. 1: Look up Constant, C. f = 0.39, F. TH = 7 ksi, n. SR = 300,000. 2: F. SR = 1000 x (C. f ...

Concrete in the tension zone of the section is neglected in the flexural analysis and design calculations, and the tension reinforcement is assumed to resist the total tensile force (Concrete tensile strength is approximately 10% of its compressive strength). 4. The maximum usable strain at extreme concrete fiber is assumed equal to 0.003. 5.
