## Is pedestal required for footing?

When the allowable bearing pressure of soil is very low, wide footing is to be provided with required bearing area. But, the depth of footing is to be reduced. If pedestal is provided on the footing it is not a problem with thinner footing. It permits the way to provide thinner footings in such type of soils.

### What is pedestal footing?

1. Column Pedestal. A concrete pedestal is a compression element provided to carry the loads from supported elements like columns, statues etc. to footing below the ground. Column pedestal is placed under column.

How do I know what size pedestal to get?

The area of contact between pedestal and supported column should be more and pedestal should have equal height as its width to avoid bending and shear movements. The allowable bearing stress depends upon the ratio of column contact are to pedestal gross area.

What is stepped footing?

The stepped footing is also known as a Stepped foundation. The stepped footing is a simple type of isolated footing which is provided over soil having less bearing capacity. Because of low soil capacity load need to be transferred on the larger area. Stepped footing are stepped upon one another.

## How many types of footing are there?

There are four types of shallow foundation: Individual footing or isolated footing. Combined footing. Strip foundation.

### What is the height of pedestal?

The pedestal height is the height of a polarization signature above 0 and the value is calculated by averaging the following four polarization combinations: orientation 0 degrees, ellipticity -45 degrees; orientation 90 degrees, ellipticity -45 degrees; orientation 0 degrees, ellipticity 45 degrees; orientation 90 …

Why are concrete pedestals used?

A concrete pedestal is a compression element provided to carry the loads from supported elements like columns, statues etc. to footing below the ground.

How wide should footings be?

“The depth depends on what the ground is like you have to dig to solid ground. For a single storey building strip foundations will typically be 450mm wide and at least 200mm deep, and for two storeys 600mm wide and 200mm deep.”

## Why pedestals are provided above the footings?

If pedestal is provided on the footing it is not a problem with thinner footing. It permits the way to provide thinner footings in such type of soils. As discussed above, pedestals are provided above the footings. For small load carrying columns, the pedestals are designed without any reinforcement and with height less than three times its width.

### Can pedestals be used for large load columns?

But this is only limited to small load ranges. But in the case of large load columns, construction and design of pedestals is same as reinforced columns for major loads. Reinforcement is also provided for the pedestals but the amount of reinforcement is 0.15% of its cross sectional area.

What is the construction of a concrete pedestal?

Construction of Concrete Pedestal As discussed above, pedestals are provided above the footings. For small load carrying columns, the pedestals are designed without any reinforcement and with height less than three times its width. Generally hollow concrete blocks are used and the hollow place is filled with concrete.

How to calculate post frame construction footing size?

Post frame construction footing size calculations are easily determined because of its simple load bearing structure. Typical post frame construction involves a series of posts opposite each other with a truss or rafters spanning the distance. The ultimate load is the defined by area of the roof carried by each post.
