High Strength Bolts: A Primer for Structural Engineers

A technical manual for structural engineers regarding the selection, installation, and design of high-strength bolts and historical rivets. It differentiates between common bolts (A307) and high-strength varieties (A325 and A490), detailing their mechanical behavior under tension, shear, and combined loading. The text emphasizes modern installation techniques such as the turn-of-nut and calibrated wrench methods, alongside specialized hardware like tension-control bolts and direct tension indicators. Engineers are provided with specific criteria for managing slip-critical and bearing-type joints, as well as complex structural phenomena like prying action, shear lag, and fatigue. Furthermore, the document outlines essential inspection protocols and maintenance considerations, including the reuse of fasteners and the impact of various hole types on connection integrity.You can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/civil_engineering_made_simpleProduced by:https://www.podcaistudio.com/
