Q

Refers to concrete elements that are used as nonstructural cladding elements; Most common use is in precast concrete curtain walls

A

Architectural precast

27
Q

Included all elements of a building’s structural framing

A

28
Q

__________ concrete foundation walls require form work and access to place the concrete.

A

Cast in place

29
Q

____________ masonry foundation walls utilize easily handled small units and do not require formwork.

A

Concrete

30
Q

are plate structures that are reinforced to span either one or both directions of a structural bay.

A

Concrete slabs

31
Q

is uniformly thick, reinforced in one direction, and cast integrally with parallel supporting beams.

A

One way slab

32
Q

A __________ slab is cast integrally with a series of closely spaced joists, which in turn are supported by a parallel set of beams

A

joist or ribbed (One way joist slab)

33
Q

Designed as a series of T-beams, ________ are more suitable for longer spans and heavier loads than one-way slabs

A

Joist slab

34
Q

A ____________ of uniform thickness may be reinforced in two directions and cast
integrally with supporting beams and columns on all four sides of a square or nearly
square bays.

A

two way slab

35
Q

two-way slabs are usually constructed as _____________ without beams

A

flat slabs and plates

36
Q

A ______ is a two-way concrete slab reinforced by ribs in two directions. ________ can carry heavier loads and span longer distances than flat slabs.

A

Waffle slabs (two way waffle slab)

37
Q

A _________ is a concrete slab of uniform thickness reinforced in two or more directions and supported directly by columns without beams or girders

A

Flat plate (two way flat plate)

38
Q

A _________ is a flat plate thickened at its column supports to increase its shear strength and moment-resisting capacity

A

flat slab (two-way flat slab)

39
Q

Each pair of external columns supports a along-spanning beam or girder. This system suits long, narrow buildings, especially when a column-free space is desired.

A

One way beam system

40
Q

is corrugated to increase its stiffness and spanning capability. The floor deck serves as a working platform during construction and as formwork for a site-cast concrete slab.

A

Metal decking

41
Q

serves as permanent form work for a reinforced concrete slab until the slab can support itself and its live load

A

form decking

42
Q

serves as tensile reinforcement for the concrete
slab to which it is bonded with embossed rib patterns.
