A shear wall is a vertical structural element designed to resist lateral forces, mainly wind and earthquake loads, that act parallel to its plane. Built from reinforced concrete, wood panels, masonry, or steel, a shear wall collects horizontal forces from the floors and roof and carries them down to the...
Skyscrapers stay up because two systems work together: a deep foundation that transfers the building's weight to firm soil or bedrock, and a stiff vertical skeleton of columns, cores, and frames that resists wind and earthquake forces. Every load, from gravity to a typhoon gust, follows a continuous path down...
A retaining wall is a structure that holds back soil or rock to keep ground at two different heights on either side of it. Retaining wall types include gravity, cantilever, sheet pile, anchored, and mechanically stabilized earth walls. Each handles different heights, soil conditions, and site constraints, so the right...
The footing vs foundation question comes down to scope: a footing is the widened base that sits directly on the soil and spreads a load across more ground, while the foundation is the whole substructure that carries the building down to that footing. Every footing is part of a foundation,...
A pile foundation is a deep foundation made of slender columns of concrete, steel, or timber driven or bored into the ground. It carries a structure's load past weak surface soil down to stronger soil or rock, supporting buildings, bridges, and towers where shallow footings would settle or fail. When...
