For the brick walls, common thickness of the load bearing wall is taken to be 230 mm (9 inches) whereas for concrete blocks it may vary from 8 inches to 4 inches.
A partition wall is a thin wall, about 10 centimeters thick, while load-bearing walls are usually 30 centimeters thick or more. Differentiating a load-bearing wall from another type of wall or dividing elements in buildings is essential to carry out renovations and maintenance measures.
ACI 318-19, Section 11.3. 1.1 states that the thickness of bearing walls shall be greater than 1/25 the lesser of unsupported length and unsupported height.
A typical foundation wall minimum thickness of eight inches applies to walls eight feet or less with no more than seven feet of soil pressing against it. Foundation walls taller than eight feet with more than seven feet of soil pressing against it requires a larger foundation wall 10 to 12 inches in width.
As a practical consideration, residential designers need to keep in mind that concrete foundation walls are typically 6, 8 or 10 inches thick (nominal). The typical concrete compressive strength used in residential construction is 2,500 or 3,000 psi, although other strengths are available.
Concrete surfaces that support large trucks, heavy machinery, or steady traffic need concrete rebar reinforcement, and any structural concrete, like walls in buildings, should definitely include rebar.
As specified by ACI-318, a minimum of 3 inches of concrete cover over steel reinforcement is required when concrete is in contact with soil. In addition, ACI-318 does not permit a depth less than 6 inches for reinforced footings supported by soil.
The concrete core may vary from 140 mm to over 300 mm depending upon the structural design, while the two leaves of insulation may vary from 100 mm to 300 mm depending on the thermal insulation specification. Consequently, total wall thickness may be between 250 mm and 600 mm.
According to IS 456:2000, clause 32.1.
1) Minimum thickness of load bearing RCC wall should be 100 mm. 2) If the story height is equal to length of RCC wall, the percentage increase in strength is 10.
Bearing walls of one-story buildings shall not be less than 6 inches (152 mm) thick. However, the overall thickness of cavity or masonry-bonded hollow walls shall not be less than 8 inches (203 mm), including cavity. 2109.4.
Plain bearing dimensions that result in wall thicknesses of less than 1mm or even 0.5mm are difficult to make, depending on the other dimensions. In the case of metal plain bearings, therefore, the dimensional stability and availability of metal sheets decide whether the bearings can be manufactured.
When bearing wall heights do not exceed 10 ft. 2 x 4 framing is generally code compliant. Here at Medeek Design we typically only specify 2 x 4 studs @ 16" o.c. spacing, for small sheds and garages with a building widths less than 16 feet.
For the brick walls, common thickness of the load bearing wall is taken to be 230 mm (9 inches) whereas for concrete blocks it may vary from 8 inches to 4 inches.
Consider the wall's material: Masonry walls made out of materials like stone, brick, or concrete are almost always load-bearing walls and can be exterior or interior walls. Consult a professional: If you are still unsure if a wall is load-bearing, consult a structural engineer or contractor.
According to the Concrete Block Association, loadbearing internal walls should have a minimum thickness of 90mm, although most construction projects use blocks that are 100mm thick because these are widely available.
ICF walls come in 4”, 6”, 8”, 10” and 12” thickness (some manufacturers go even thicker). Generally, 4” walls are only used for non-loadbearing applications such as demising walls in apartments, hotels or dormitories. 5.
Lift shafts can be built from 1200mm each way up to 2750mm, in increments of 50mm. Wall thickness starts at 150mm, but this can be increased to 200mm or 250mm. Our standard lift design supports all loading from the lift equipment during installation, operation, and maintenance.
The 6-inch core size is the standard and most commonly used in ICF construction. The Standard 6-inch core is used for below-grade walls in residential. Up to 9 stories above grade, the benefit points we discuss are based on the 6-inch core block (wind resistance, fire rate, storm resilience, etc).
Required Footing Sizes
In most cases, a house should have a minimum footing of 12 inches wide by 12 inches deep, with foundations that are 8 to 10 inches thick. This should be enough to support house weight and resist lateral soil and water pressure.
The minimum depth of foundation for the load-bearing wall is 900 mm. The design of building foundations is performed based on prescribed serviceability and strength criteria laid down by various standard codes adopted by different countries.
In conclusion, deciding between a cinder block retaining wall and a concrete one is a matter of preference. Both materials have unique benefits and drawbacks that must be evaluated before making a decision. Cinder blocks are often more affordable, but not as long-lasting as concrete.
A 2-inch concrete thickness is generally not sufficient for a driveway that will be subjected to regular vehicle traffic. While it may be suitable for light-duty applications like footpaths or patios, a driveway requires a thicker concrete slab to withstand the weight and impact of vehicles.
The most common fire rated drywall is known as type X, which is 5/8 inches thick, placed on each side of 2 by 4 or 2 by 6 inch wood studs and has a minimum fire rating of 1 hour.
