Interior Design: High-Rise Buildings Lecture Objectives

Study Notes

A high-rise building is a tall, multistory building that requires a system of mechanical vertical transportation, such as elevators.
The skyscraper is a very tall high-rise building.

The first high-rise buildings were constructed in the United States in the 19th century.
High-rise buildings arose in urban areas where increased land prices and significant population densities created a demand for buildings that rose vertically rather than spread horizontally.

Tube structure with perimeter lateral force-resisting systems internally braced by rigid floor diaphragms.
Braced tube: a framed structure tied together by a system of diagonal braces.
Trussed tube: trussed wall frames of widely spaced columns tied together by diagonal or cross bracing.
Latticed truss tube: perimeter frames of closely spaced diagonals with no vertical columns.
Bundled tubes: an assembly of narrow tubes tied directly to each other to form a modular structure.
Tube-in-tube structure: an inner braced core added to the perimeter tube to improve its shear stiffness.

Viscoelastic devices installed at structural joints to absorb energy generated by wind or earthquake forces.
Internal damping: natural damping that occurs as a building undergoes elastic or plastic deformation.
Types of internal damping: hysteresis damping, frictional damping, and viscous damping.

Require incredibly strong bases and walls due to immense weight.
Use pilings to anchor the building to the bedrock underground.
Example: Burj Khalifa, the world's tallest building, uses specially treated and mixed reinforced concrete.
