FAQ: What Is Bearing Capacity Of Foundation?

Bearing capacity of a foundation is the maximum load that can be applied on a foundation, before failure or uncontrolled deformations occur.

What is meant by bearing capacity?

In a nutshell, bearing capacity is the capacity of soil to support the loads that are applied to the ground above. It depends primarily on the type of soil, its shear strength and its density. It also depends on the depth of embedment of the load – the deeper it is founded, the greater the bearing capacity.

How do you calculate bearing capacity of a foundation?

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.

What is meant by soil bearing capacity?

Definition. Bearing capacity is the maximum stress or pressure that a footing can sustain without failure of the soil or rock that is supporting the footing.

What is the bearing capacity of concrete?

Imposed loads varies from approximately 1.5 kN/m2 (153 kg/m2) in domestic buildings to approximately 10 kN/m2 (1053 kg/m2) in heavy industrial areas. 500 kg/m2 is typical for office, storage space and similar.

What is the safe bearing capacity?

Net safe bearing capacity (qns): is the maximum net pressure intensity to which the soil at the base of the foundation can be subjected without risk of shear failure. 5.

What is load bearing capacity?

Loadbearing capacity is the maximum ability of a structural member or material to take loading before failure occurs. For example, before the onset of unacceptable bending.

How do you find weight bearing capacity?


  1. Loads on the RCC Slab. Self-weight= concrete unit weight * Volume of concrete. = 24 * 0.1= 2.4 KN/m2
  2. Loads on the Beam. Self-weight= concrete unit weight* beam width*beam height. =24 * 0.28*0.25= 1.68 KN/m.
  3. Compute Applied Moment. Assume partial fixity of columns.
  4. Geometry of the Original Section.

How do you calculate safe bearing capacity?

Safe Bearing Capacity of Soil Testing Procedure:-

  1. Firstly Excavate a pit of required depth. ( preferably equal to the depth of foundation)
  2. Take a square cube of known weight and dimensions.
  3. Now drop the square-cube on the pit with a known height.
  4. Measure the impression made on the pit by square cube using the scale.

What is foundation bearing?

Bearing capacity of a foundation is the maximum load that can be applied on a foundation, before failure or uncontrolled deformations occur.

Which soil has highest bearing capacity?

Gravel and sand are the soils with higher bearing capacity while silts and clays typically have lower capacities.

Is concrete a load bearing?

Exterior walls are almost always load-bearing, and internal load-bearing walls can be identified by looking for any beams which are submerged into the concrete. Walls which do not connect to the foundation are not considered load-bearing.

How much weight can a foundation hold?

A typical interior footing should support a 10,000-pound load. Even between footings, a post-tensioned slab can safely bear about 1,000 pounds per inch of thickness, or about 5,000 pounds for a typical 5-inch-thick residential slab.

What is concrete bearing?

Thank you for posting your query. The bearing strength of concrete is simply the compressive strength of the concrete and the ratio of the total surface area to the load bearing area (known as bearing ratio).
