Steel Structure Design

1.The effective length of a compression member of length L held in position and restrained in direction at one end and effectively restrained in direction but not held in position at the other end, is

L 0.67 L 0.85 L 2 L

2.The ratio of shearing stress to shearing strain within elastic limit, is known as

modulus of elasticity shear modulus of elasticity bulk modulus of elasticity tangent modulus of elasticity

3.For determination of allowable stress in axial compression, Indian Standard Institution has adopted

Euler's formula Rankine formula Engesser formula Secant formula

4.The method of design of steel framework for greatest rigidity and economy in weight, is known as

simply design semi-rigid design fully rigid design none of these.

5. If the pitch is 6 cm and rivet value is 4 tonnes, the number of rivets required for a riveted connection carrying an eccentric load of 15 tonnes at a distance of 30 cm from the centre line, is
