What will be an ideal response?
Whenever two steel elements are joined together in a shear connection, the surfaces of the connection elements in contact have a tendency to slide past each other along these contact surfaces. Th is tendency must be resisted by the bolts. When there is one traverse section where this sliding might occur, the bolts are said to be in single shear. When there are two traverse sections, or shear planes, the bolt is said to be in double shear.
