Transmitting the building load to the soil is the ______ of foundation.
Purpose
It performs properly if the soil also behaves properly
Structural foundation
It is the process of the building outline or perimeter on the ground is known to be…
Laying and staking.
Before a foundation for construction is begun the perimeter of the house should be laid out on the…
Ground first
It is below the surface of the ground also called as the substructure
Foundation
All weight in a structure, made up of immovable materials
Dead load
is an enlargement at the lower end of a wall, pier or column to distribute
the load into the ground
Footing
is a steel column used to support girders and beams.
Lally column
a block of concrete supporting the floor of a building.
Pier
are long posts driven into the soil in swampy locations upon which the
foundation footing is laid.
Piles
is a column used for supporting parts of a structure.
Pillar
is a foundation reinforced concrete and foundation floor.
Slab
wooden stick or post drive to the ground.
Stake
are wood sticks nailed horizontally to the stake
Batter boards
for establishing reference points.
Level transit
which is transparent and ¼” Ø filled with water to establish
level of horizontal lines.
Plastic level hose
Connecting established points
String or chord
includes wall footing and column footings whether they
are independent or combined wherein digging of the soil extends to 1.5 meters.
Shallow excavation
is for large building projects as this requires almost total
extraction of the soil at the site. This requires sheeting and shoring of the ground
to project adjoining properties. The process is defined as providing temporary
support to the structure or ground during excavation.
Deep excavation
d is the filling in of the excavated portion after the
foundation has been laid out.
Backfilling
What are designs of foundation?
•dead load plus the live load
•load effects of wind, head, water, earthquake
•explosive blasts
Shallow excavation includes?
Matt and spread footing
Deep excavation includes?
Piles, piers, and caissons
Reasons for the movement of the foundation?
•soil bearing capacity
•failure or deflection of the foundation structure
•sheer distortion of the soil
•compression of the soil
