-
The greatest gauge of long rivets should not exceed (where d is the diameter of the holes).
-
Maximum permissible slenderness ratio of a member normally acting as a tie in a roof truss, is
-
If d is the distance between the flange angles,
-
The side thrust T on the tie rods provided at the end beam of jack arch of rise R, is calculated from the formula
-
When the depth of a plate girder is at least n times the depth of vertical leg of the flange angles, the girder is known as deep plate girder, if n is
-
Stiffeners are used in a plate girder
-
The channels get twisted symmetrically with regard to its axis
-
The stiff portion of a bearing stiffener is taken equal to
-
Effective length of a column effectively held in position at both ends and restrained in direction at one end, is
-
The strength of ISA 125 = 75 x 10 mm used as a tie member with its longer leg connected at the ends by 27 mm diameter rivets, is
