Common Terms
Certain Terminologies/Common Terms that will be used for the design of bolted connections are listed below:
Pitch:
It is defined as the centre to centre distance between two consecutive bolts measured along a parallel to the direction of load.
Gauge distance:
It is the centre to centre distance between two consecutive bolts measured in a perpendicular direction to the applied load.
End distance:
It is the distance in the direction of load from the centre of a bolt hole to the end of the element.
Edge distance:
It is the distance perpendicular to the direction of load from the centre of the bolt hole to the adjacent edge of the member.
Nominal diameter of bolt:
It is the diameter of the shank portion of the bolt.
Diameter of bolt hole:
It is the diameter of holes in which bolts are driven.
