A

Construction joint

18
Q

A joint formed when a concrete surface hardens before the next batch of concrete is palced

A

19
Q

A cantilever wall that is reinforced with a masonry structure extending upward from the foundation or from the inner face of the retaining wall, to provide additional resistance to thrust and are placed at regular intervals

A

Counter

20
Q

A cantilever wall that is reinforced with a masonry structure extending upward from the foundation or from the outer face of the retaining wall, to provide additional resistance to thrust and are placed at regular intervals

A

Buttress

21
Q

A horizontal or nearly horizontal system including horizontal bracing system, that act to transmit lateral forces to the vertical resisting elements

A

Diaphragm

22
Q

A structural member of a horizontal bracing system that takes axial tension and compression; parallel to the applied load that collects and transfer shear to the vertical resisting elements or distributive loads within the horizontal bracing system

A

Diaphragm strut

23
Q

A short steel bar extending from one concrete element to another as for instance a concrete foundation to a concrete column

A

Dowel

24
Q

A long pin of steel or wood, made with or without the head, driven through the timber and into an adjacent timber to hold them together and to transmit stresses

A

Drift bolt

25
Q

A rich cement mortar which is applied by spraying under high air pressure

A

Gunite

26
Q

A concrete beam placed directly on the ground to provide foundation for the superstructure

A

Grade beam

27
Q

A deformed bar, embedded in a concrete construction at a joint and designed to hold a butting edges together, not designed for direct load transfer

A

Tie bar

28
Q

A watertight pipe 300-600 mm in diameter with a flared top used in depositing concrete under water

A

An art of pacing new foundation under old foundation

29
Q

Ratio of volume of air plus water to the volume cement

A

Void-cement ratio

30
Q

The ratio of the amount of water with the amount of cement in a concrete or mortar mixture

A

Water cement ratio

31
Q

Loads of constant magnitude that remains in one position

A

Dead load (DL)

32
Q

Load that may change in magnitude and position

A

Live load (LL)

33
Q

Load multiplied by appropriate load factors, used to proportion a members by the strength design method

A

Factored load

34
Q

Reinforcement used to resist shear and torsion stresses in a structural member; typically, bars, wires, or welded wire fabric; usually applied to lateral reinforcement in flexural members and the term ties to those in compression members

A

Stirrups
