What is the load bearing capacity of RCC floor?
1. Loads on the RCC Slab. Live load on Slab= 2.4 KN/m2 (Office use; per Table 4-1 in ASCE standard (ASCE/SEI 10-7)).
How do you determine the strength of a concrete slab?
How to Calculate a Concrete Pad Load
- Not all concrete is the same strength.
- Measure the length and width of the top surface of the concrete pad in inches and then multiply them to get the pad’s area in square inches.
- Knowing a concrete pad’s thickness or depth is vital if you need to determine the load it can withstand.
How is RCC load calculated?
Dead Loads:
- Weight of beam = (0.3 x 0.45) x 5 x 25 = 16.875 kN.
- U.D.L in the beam = 16.875/5 = 3.375 kN/m.
- Weight of slab = 0.15 x 25 = 3.75 kN/m2
- Load on 6 m span = 8 x 0.15 x 25 = 30 kN.
- Thus, U.D.L = 30 / member length = 30/6 = 5 kN/m.
- Load on 4 m span = 4 x 0.15 x 25 = 15 kN = 15 / member length = 15/4 = 3.75 kN/m.
What is the load bearing capacity of a 150 mm thick RCC slab?
Load capacity of simply supported concrete slabs
| Thickness (mm) | Self Weight (kg/m2) | Total Load |
|---|---|---|
| kN/m2 | ||
| 100 | 240 | 7.26 |
| 125 | 300 | 7.85 |
| 150 | 360 | 8.44 |
How do you calculate floor loads?
Divide the maximum load of one joist by the area supported by one joist: 462 kg (1,019 lb) / 1.72 square metres (18.7 sq feet) = 269 kg per square metre (54.5 lb per square foot). This number tells you how much load your floor can support for each square metre of floor space.
How strong is 3 inches of concrete?
So, the “4,000 PSI” rating is for the standard 4-inch thickness of a residential concrete slab. This means that a 3-inch slab will be slightly weaker, while a 5-inch slab will be slightly stronger, in terms of compressive strength. Tensile strength is a bit harder to measure.
How do you calculate the load bearing capacity of a concrete foundation?
The safe bearing capacity of soil is 250 kN/m2 at a depth of 1 m below the ground level. Use M 20 and Fe 415. Given P = 1500 kN, qc = 250 kN/m2 at a depth of 1 m below the ground level. Assuming the weight of the footing and backfill as 10 per cent of the load, the base area required = 1500(1.1)/250 = 6.6 m2.
How is load bearing capacity calculated?
Bearing capacity is one method of measuring this strength. Researchers can calculate the bearing capacity of soil by determining the limit of contact pressure between the soil and the material placed on it.
How is floor strength calculated?
Multiply the maximum load per square metre by the total area of the floor. If the example floor is 6 by 9 metres (20 by 30 feet), the total area is 54 square metres (600 square feet); 54 x 269 = 14,526 kg (32,024 lb). This number tells you the total load capacity of your floor.
What is floor load capacity?
Floor load capacity is the total maximum weight a floor is engineered to support over a given area. In the U.S. it is expressed as pounds per square foot. Floors are engineered to carry a maximum static load and a maximum dynamic load that can’t be exceeded without the risk of compromise to the structure. Examples.
What is the strength of RCC after 28 days?
Strength of RCC is defined as compressive strength after 28 days, expressed as M15, M20, where M stands for Mix and 15 stands for 15 N/mm 2 (n/mm 2 must be read as ‘Newton’s per millimeter Cubed) compressive strength at 28 days.
How to estimate cement, sand and aggregate for RCC?
With the help of our online Reinforced concrete or RCC calculator, you can estimate the quantity of cement, sand and aggregate rquired for your RCC foundation, beam and structural design.
What does RCC stand for in concrete category?
Reinforced cement concrete or RCC is a composite material in which concrete’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.
How is the thickness of a concrete floor determined?
A.: Most designers calculate the required thickness of a floor based on the flexural strength of the concrete. Flexural strength is estimated by the modulus of rupture, which is assumed to vary with the square root of the compressive strength.
