Depressed Strand:
Apretensioning tendon that is pulled to the bottom of the beam at the centre of the span to follow more closely the path of tensile forces in the member.

Diamond Saw:
A tool with a moving chain,belt,wire,straight blade, or circular blade whose cutting action is carried out by diamonds.

Diaphragm Action:

An industrial tool for giving identical form of repeatedly produced or continously generated units, such as a shaped orifice for giving form to a column of clay,a steel wire,or an aluminum extrusion,a shaped punch for making cutouts ofsheet metal or paper, a mold for casting plastic or metal,a cutting tool that produces screw threads.

Die- Cut:
Manufactured by punching from a sheet material.

Differential Settlement:
Subsidence of various foundation elements of a building at differing rates.

A louver shaped so as to distribute air about a room.

Dimension Stone:
Building stone cut to a Rectangular shape.

Distribution Rib:

Double glazing:
Two parallel sheets of glass with an airspace between.

Double-hung window:
A window with two overlapping sashes that slide vertically in tracks.

Double shear:

Double-strength glass:
Glass that is approximately 1/8 inch(3mm) in thickness.

Double tee;
A precast concrete slab element that resembles the letters TT in cross section.

Dovetail slot anchor:
A system for fstening to concrete structure that uses metal tabs inserted into a slot that is small at the face of the concrete and larger behind.

A short cylinderical rod of wood or steel,a steel reinforcing bar that projects from a foundation to tie it to a column or wall, or from one section of a concrete slab or wall to another.

A vertical pipe for conducting water from a roof to a lower level.

Removal of water.

Drawn glass:
Glass sheet pulled directly from a container of molten glass.

Lateral deflection of a building caused by wind and earthquake loads.
