Methods used for finding slab thickness varies for different types of slabs.
1 story reinforced concrete wall thickness.
So taller walls in heavier soils should be made thicker or with stronger concrete.
Thickness of concrete slab depends on loads and size of the slab.
The rebar increases the wall s strength without expanding its thickness.
Footing thickness 8 to 12 inches.
Aci 318 allows two approaches to the design of reinforced concrete with some limits on wall thickness and the minimum amount of steel reinforcement.
Reinforced concrete wall is used in case where beam is not provided and load from the slab is heavy or when the masonry wall thickness is restricted.
In general 6 inch 150mm slab thickness is considered for residential and commercial buildings with reinforcement details as per design.
Cabo one and two family dwelling code.
Increasing the strength of the concrete mix or the thickness of the wall increases the wall s capacity.
Reinforced concrete wall is classified as.
Reinforced concrete concrete walls that contain steel bars or rebar offer more resistance to external stresses than concrete with no reinforcement.
As soon as you go higher or have greater depths of soil pushing against the wall you need to increase the thickness to 10 inches.
Plain concrete wall when reinforcement 0 4 reinforced concrete wall when reinforcement gt.
Concrete calculator figure out how much concrete you ll need for your footings.
Strength reduced from 136 7 to 114 9 in kips.
However aci 318 also permits these requirements to be waived in the event that structural analysis demonstrates adequate strength and stability in accordance with aci 318 14 2 7.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well.
Footing depth varies based on frost line and soil strength some footings can be shallow while other must be deep.
In some situations the rebar is critical to the structural integrity of the wall.
The thickness of concrete is an important factor in load bearing strength but to conserve resources and avoid over building other factors are also taken into consideration.
Table 4a is based directly on the aci method but for table 4b the author has applied a reduced strength reduction factor a factor of safety.
2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16.
For example one way slab thickness calculation is different and easier from hellip.
