How can steel structures be made from bolts or bolts? High strength bolts are generally used for installation or production?
The high-strength bolt is used to calculate the force of the bolt group, and is also used for node calculation.
It should be said that the steel structure is made unless a small number of bolts are used for positioning in the process equipment and the bolt is removed after completion of the assembly. All other bolts are mounting bolts, including high strength bolts. The production process does not use high-strength bolts, high strength bolt than ordinary bolt because of high cost and high strength bolt cannot be used for the two time in technology (because of the bolt torque coefficient needs to be determined, determination of the torque coefficient is discarded).
You must understand that a mounting bolt is used for installation, which is now in the welding joints of steel structure connection, the first fixed installation bolt and welding, the calculation only considers the weld resistance, the bolt itself does not force, with ordinary bolt.
