1.
Computation. Compute the number of CHB and Reinforced bar needed on the given
scenario. (Each RSB is 6 meters in length and the height of CHB id 18 cm.)
1. A wall 1.1 meters from the ground with a length of 3 meters is to be constructed using a 4"
concrete hollow block (CHB). 2 layers of CHB will be buried on the ground. The distance of the
vertical reinforce steel bar (RSB) is 60cm and the horizontal RSB is to be placed after every 3
layers of CHB.

Answer:

To compute the number of CHB (Concrete Hollow Blocks) and Reinforced Steel Bars (RSB) needed for the given scenario, we will follow these steps:

Given:

- Wall height: 1.1 meters from the ground

- Wall length: 3 meters

- CHB height: 4 inches (equivalent to 10.16 cm)

- 2 layers of CHB will be buried on the ground

- Vertical RSB spacing: 60 cm

- Horizontal RSB to be placed after every 3 layers of CHB

- Each RSB is 6 meters in length

Let's calculate the number of CHB needed first:

1. Calculate the total height of the wall including the buried CHB:

Total wall height = Wall height + 2 * CHB height

Total wall height = 1.1 meters + 2 * 10.16 cm = 1.1 meters + 20.32 cm = 1.1 meters + 0.2032 meters = 1.3032 meters

2. Calculate the number of CHB layers:

Number of CHB layers = Total wall height / CHB height

Number of CHB layers = 1.3032 meters / 0.18 meters = 7.239 (round up to 8 layers for safety)

3. Calculate the total number of CHB needed:

Total CHB needed = Wall length * Number of CHB layers

Total CHB needed = 3 meters * 8 layers = 24 CHB

Next, let's calculate the number of RSB needed:

4. Calculate the number of horizontal RSB needed:

Number of horizontal RSB = Number of CHB layers / 3 (placed after every 3 layers)

Number of horizontal RSB = 8 layers / 3 ≈ 2.67 (round up to 3 bars for safety)

5. Calculate the number of vertical RSB needed:

Number of vertical RSB = Wall length / Vertical RSB spacing

Number of vertical RSB = 3 meters / 0.6 meters = 5 bars

Therefore, for the given scenario, you would need:

- 24 Concrete Hollow Blocks (CHB)

- 3 Horizontal Reinforced Steel Bars (RSB)

- 5 Vertical Reinforced Steel Bars (RSB)
