# What is eccentrically loaded footing?

## What is eccentrically loaded footing?

Normal footing becomes eccentrically load footing when there is an eccentricity in the loading or when there is a bending moment at the connection of footing and the column. The eccentricity could be in one direction or in both directions.

Examples of eccentric loading activities include performing a calf raise off the ledge of a stair, an exercise that has been shown to decrease the risk of achilles tendon injuries. Another example is the nordic curl exercise, which have been shown to help reduce the risk of hamstring strains.

## What is an eccentrically loaded column?

Eccentric loading on column. When the load acting on the column is offset from the centroid of the column, then it establishes the bending of column along with the axial stress. This offset loading of the column is referred as eccentric loading.

## What is an eccentric foundation?

An eccentric foundation is a foundation whereby the wall sits on the outer edge of the foundation.

## What are the reasons for the eccentricity in footing?

The eccentric footing is designed in such a way that the C.G (center of gravity) of the superimposed load coincides with the C.G of the base area so, resulting in uniform bearing pressure. This footing is subjected to concentric loading. W1 is a super-imposed load, including the weight of the wall per unit length.

## What is a buckling load?

The maximum load that can be imposed on a string of drill rods, casing, or pipe, or on a drill tripod, derrick, or mast without the string buckling; also, a part being bent or buckled.

## Is eccentric against gravity?

The concentric phase is the phase of the movement that is overcoming gravity or load, while the eccentric phase is the phase resisting gravity or load. So for push ups the concentric phase is the up phase where gravity is overcome, and the eccentric phase is the downward phase where gravity is resisted.

For example, if the wall (or column) under construction is near some other property, it will not be possible to spread the footing to both the sides of the wall or column. Such a situation is shown in Fig. 3.7. FIG. 3.7 ECCENTRIC LOADING.

## How are eccentrically loaded foundations different from conventional foundations?

The design of eccentrically loaded foundations is not the same as the conventional foundation where the column load is applied at the center of the footing. Normal footing becomes eccentrically load footing when there is an eccentricity in the loading or when there is a bending moment at the connection of footing and the column.

## When is it not possible to spread footings?

However, in some cases, it may not be possible to do so. For example, if the wall (or column) under construction is near some other property, it will not be possible to spread the footing to both the sides of the wall or column. Such a situation is shown in Fig. 3.7. FIG. 3.7 ECCENTRIC LOADING.

## How are concrete foundations and footings are designed?

Reinforced concrete foundations, or footings, transmit loads from a structure to the supporting soil. Footings are designed based on the nature of the loading, the properties of the footing and the properties of the soil.
