TOPIC 2: PLACEMENTS

Question 1

Involves the accurate positioning of reinforcing bars (rebar) within structural elements such as beams, columns, slabs, and footings to ensure
optimal load distribution, strength, and durability.

Answer 1

Placement

Question 2

Is critical to achieving the desired performance of reinforced concrete structures.

Answer 2

Proper Placement

Question 3

Larger diameter bars run the length of the beam and resist the tensile forces
that occur when the beam bends.

Answer 3

Longitudinal Bars

Question 4

Smaller diameter bars are arranged in closed loops at regular intervals along the beam and resist the diagonal tensile stresses caused by shear.

Answer 4

Shear Reinforcement (Stirrups)

Question 5

Runs the length of the column and is used to resist flexural tensile stresses.

Answer 5

Longitudinal Reinforcement

Question 6

Prevents longitudinal bars from buckling,
avoids shear failure, and confines the concrete
core.

Answer 6

Transverse reinforcement (Ties and Hoops)

Question 7

Typically placed at the bottom of the slab and run in a shorter direction.

Answer 7

Main Reinforcement

Question 8

Placed on top of the main reinforcement bars and run in a longer span direction.

Answer 8

Distribution Bars

Question 9

Rebar reinforcement is poured into an excavated trench to create footings.

Answer 9

Main Reinforcement

Question 10

Usually in the form of stirrups, shear reinforcement resists shear forces and holds the main reinforcement in place.

Answer 10

Shear Reinforcements

Question 11

Used to strengthen walls during construction or renovation.

Answer 11

Vertical and Horizontal Reinforcement
