• For example, the bearing capacity of a bolt can be determined using the formula: P = A * σ * F

• Where P is the bearing capacity, A is the contact area, σ is the allo...read more

Load bearing piles support the weight of the structure while friction piles transfer the load to the soil through friction.

• Load bearing piles are designed to support the weight of the structure and transfer it to the soil below.

• Friction piles rely on the friction between the pile and the soil to transfer the load to the ground.

• Load bearing piles are commonly made of concrete or steel while friction piles are usually made of timber or concrete.

• Examples of load bearing piles in...read more

A footing is a structural element that supports the weight of a building and transfers it to the ground.

• Footing is the lowest part of a building's foundation
