Unformatted text preview: CE311 FALL 2010 Lesson 18: Bolted Tension Members I An appeaser is one who feeds a crocodile, hoping it will eat him last. - Winston Churchill LESSON 18: BOLTED TENSION MEMBERS I: YIELD AND FRACTURE Friday, October 08, 2010 LESSON OBJECTIVES 1. Explain why yielding must never be allowed along any structural member, but it is allowed (locally) on a connection (around bolt holes). 2. Explain why yielding is allowed at the connection , so that the limiting stress for connections is the ultimate (fracture) stress. 3. Calculate the controlling load capacity P n , considering yielding of the member and fracture of the connection. 4. Calculate the allowable tensile load (ASD) P allow and the reduced design capacity (LRFD) P n , based on yielding and fracture limit states. 5. Judge when the shear lag factor will tend to be lower (greater reduction in strength). 6. Determine the shear lag factor U, using the Case 2 equation or by using one of the generic U values (cases 1, 3, 4,...
