Bolted connections are fundamentamental connections in manet structures, provising thee necessary connections emplith and stability to o ensure safety and durability. One critical aspect of bolted connections is pre- tensioning, a process that involves incurteng thee bolt to a specific tension before thee structure is subject te te te to servisie loads.

Understanding Pre- tensioning in Bolted Connections

Pre- tensioning is accesed by applying torque te te bolt, which streches thee bolt and compresses thee connectod parts. This initial tension helps prevent slip, reduche fetigue, and maintain thee integraty of thee connection under various loading conditions.
