Earthquake Engineering

The level at which the earthquake motions are considered to be imparted to the structure

Total designed lateral force or shear at the base of a structure.

Structural system without a complete vertical load carrying space frame.

An element at edges of opening or at perimeters of shear walls or diaphragms.

Vertical truss system of the concentric or eccentric type, which is provided to resist lateral forces.

Complete space frame that provides support for gravity loads.

A structural system relying on cantilevered column elements for lateral resistance

Column element in a lateral-force-resisting system that cantilevers from a fixed base and has minimal moment capacity at the top

Transfers lateral forces from a portion of a structure to vertical elements of the lateral force resisting system.

Element of an architectural, electrical, mechanical, or structural system.
