Lotus Riverside, Shangai, China Building fell over after workers began excavating an
underground garage which caused the bank of the
river next to the complex to collapse.
Foundation Transfer the structural loads of a building safely into
the ground. The components of the foundation
system depend on the size of the building and the
loads it needs to support.
,58 Story Millennium Tower, San Completed in 2008. Has sunk 16 inches and has
Francisco, Luxury Apartments started to lean 2 inches since 2009. Some engineers
believe that it is the type of foundations, in this case,
friction piles, that are allowing the building to sink
because the building is not supported by bedrock on
end-bearing piles.
58 Story Millennium Tower, San Lawyers have filed a lawsuit against the buildings
Francisco, Luxury Apartments developers and the Transbay Joint Powers Authority, a
government entity building a transportation hub next
door to the Millennium Tower. Lawyers say that
sinking had already begun significantly before work
on the transport terminal started; the foundation
does not go into bedrock; it is all landfill. It used to
be part of the bay.
3 Types of Footings 1. A retaining wall. 2. Grade beam. 3. The interior
partition is a bearing wall and it needs to be
supported or thickened at the slab.
3 Parts of a Structure Superstructure, Substructure and Foundation
Superstructure Above ground (building)
Substructure Below ground (basement)
Foundation Supports all that is above: Substructure and
Superstructure.
In a house, or mid-scale building... The foundation system can be comprised of: walls
with footings at its base OR a turned down slab.
Slab Concrete slab with footing around the perimeter.
A large scale structure will be Caissons or pilings
supported by...
Caissons Bridge
, Deep Foundations Caissons, pilings. Penetrate through layers of upper
"incompetent" soil in order to transfer loads to
competent bearing soil or bedrock below.
Foundations support: Live loads
Live Loads Non-permanent equipment: People and furnishings
Dead Loads Wight of the frame: floors, walls, ceilings, electrical
and mechanical equipment and foundations
themselves.
Wind Loads Lateral (side) downward and uplift forces on a
structure.
Rain and Snow Loads Accumulation on roof. Downward load.
Lateral Soil Loads Horizontal pressures of the earth and groundwater
against foundation.
Seismic Loads Motion of earthquakes.
Tainan, Taiwan, February 2016 Weiguan Tin cans were used to fill the concrete slab.
Jinlong (Golden Dragon Tower)

3 Requirements of a Satisfactory 1. The foundation must be safe against a structural
Foundation failure. It must support the weight of the building. 2.
The foundation must not settle in such a way that
would damage the structure of a the building. 3. The
foundations must be feasible, both economically and
technically and should not cause damage
surrounding structures or property. The site should
be suitable for the property.
