Bolted Assemblies: Traction, Shear, and Pre-Stressed Connections

This lecture covers the design and verification of bolted connections in metal structures, focusing on tension, shear, and pre-stressed assemblies. Topics include calculation examples, bolt placement, shear and tension stresses, net section breakage, and the importance of correct bolt sizing and spacing. The instructor discusses the interaction between shear and tension, the effect of prestressing on assembly serviceability, and methods for ensuring reliable connections. Various tables and figures are used to illustrate resistance values, bolt slip resistance, and the relationship between tightening torque and prestressing force.
