Question

Which of the following is correct for pitch of the bolts and gauge?

(a) pitch is measured along direction of load, gauge is measured perpendicular to direction of load

(b) pitch is measured perpendicular direction of load, gauge is measured along to direction of load

(c) pitch is measured along direction of load, gauge is measured along to direction of load

(d) pitch is measured perpendicular direction of load, gauge is measured perpendicular to direction of load

The question was posed to me in an international level competition.

My question is taken from Bolted Connections topic in chapter Bolted Connections of Design of Steel Structures

Answer 1

The correct choice is (a) pitch is measured along direction of load, gauge is measured perpendicular to direction of load

Explanation: Pitch is centre to centre spacing of bolts in a row, measured along direction of load. Gauge is the distance between two consecutive bolts of adjacent row measured at right angles to the direction of load.
