Dry service

Construction; Seismic safety

Structures wherein the maximum equilibrium moisture content does not exceed 19%.

Dressed size

Construction; Seismic safety

The dimensions of lumber after surfacing with a planing machine. Usually 1/2 to 3/4 inch less than nominal size.

Eccentrically braced frame (EBF)

Construction; Seismic safety

A diagonally braced frame in which at least one end of each brace frames into a beam a short distance from a beam-column joint or from another diagonal brace.

Concentrically braced frame (CBF)

Construction; Seismic safety

A braced frame in which the members are subjected primarily to axial forces.

Braced frame

Construction; Seismic safety

An essentially vertical truss, or its equivalent, of the concentric or eccentric type that is provided in a building frame system or dual frame system to resist shear wall.

Effective stiffness

Construction; Seismic safety

The value of the lateral force in the isolation system, or an element thereof, divided by the corresponding lateral displacement.

Effective damping

Construction; Seismic safety

The value of equivalent viscous damping corresponding to energy dissipated during cyclic response of the isolation system.
