Prestressed Concrete Structures - Pre Assessment Test

The maximum moment of resistance in a pole is generally required at:

• 1) Base

• Corner

• Edge

• Middle

The main advantage of prestressed concrete piles over traditional reinforced and concrete steel piles is:

• Moment carrying capacity

• Beam carrying capacity

• Column carrying capacity

• Foundation carrying capacity

Prestressed concrete sheet piles are ideally suited for the construction of:

• Air frond bulkheads

• Water frond bulkheads

• Half brick walls

• Full brick walls

The prominent prestressed sleepers which have been adopted by railways of various countries is:

• Single block sleepers

• Gauge sleepers

• Two block sleepers

• 1) Friction sleepers

In reinforced concrete members the prestress is commonly introduced by:

• Tensioning the steel reinforcement

• Tendons

• Shortening of concrete

• Rings

Which of the following basic concept is involved in the analysis of prestressed concrete members?

• Combined and bending stresses

• Principle stresses

• Shear stresses

• Overhead stresses

The concept which is used in many branches of civil engineering and building construction?

• Reinforced concrete

• Prestressed concrete

• Steel concrete

• Lump sum concrete

Development of early cracks in reinforced concrete is due to:

• Strains of steel

• Stresses of steel

• Ultimate load

• Bending of steel

Concrete is weak in?

• Compression

• Tension

• Loading

• Bending

The attempt to introduce permanently acting forces in concrete to resist the elastic forces is:

• Prestressing

• Loading

• Pre-straining

• Bending
