Which one of the following techniques is not covered in Project Network Analysis?
2.
In an excavation of 3,000 cub.mtr of common earth for a canal project, 6 men can be effectively employed on the job. If an output of a man is taken as 100 cub.mtr per day, the duration of excavation activity will be
3.
Air permeability method is used to determine
4.
Which of the following assumptions are correct for the lateral torsional buckling of an I-section
1. The beam is initially distorted
2. Its behaviour is elastic
3. It is loaded by equal and opposite end moments in the plane of the webbeam?
5.
A beam of size 250 mm width and 460 mm effective depth is subjected to limit state moment of 146 kNm. If M20 grade concrete and Fe415 steel are used, the area of steel required will be
6.
Which of the following are correct for cover to reinforcement?
1. The reinforcement shall have a minimum clear cover of 20 mm or diameter of such bar whichever is more.
2. At each end of reinforcing bar not less than 25 mm nor less than twice the diameter of such bar.
3. Increased cover thickness may be provided when surface of concrete is exposed to the action of harmful chemicals.
7.
A simply supported beam having 200 mm width and 450 mm effective depth supports a total uniformly distributed load of 2,00,000 N. The nominal shear stress will be nearly
8.
Which of the following are the desirable properties for efficient functioning in design for movement joint of water tank?
1. The joint should accommodate repeated movement of the structure without loss of water-tightness
2. The design should provide for exclusion of grit and debris which would prevent the closing of the joint
3. The material used in the construction of movement joints should not slump unduly in hot weather or become brittle in cold weather
9.
Which one of the following are the general design requirements of retaining wall?
1. The factor of safety against sliding should be atleast 1.5
2. The factor of safety against overturning should be atleast 2.0
3. The bearing pressure at toe should be less than the bearing capacity of the soil
4. The length of retaining wall to be cast in one go should not exceed 10 m otherwise cracks may develop
