Q

Which structural system is commonly used in situations where floor to floor height must be kept at minimum?

A

Flat plate construction

20
Q

Flat plate construction is often difficult but not impossible to….

A

Drill floors for electrical and pipes

21
Q

Which concrete structural system is usually left exposed with lighting integrated into coeffers?

A

Waffle slab system

22
Q

Waffle slab system - two way joist system?

A

Can provide support for heavier loads at slightly longer spans than the flat slab system

23
Q

Which precast concrete is commonly found in industrial bldgs , one and two story commercial bldgs, and parking garages?

A

Double tee construction

24
Q

CMU

A

Concrete masonry units, dimensions based on nominal 4 inch module

25
Q

What is the most common size of CMU?

A

8” (w) x 8” (h) x 16” (L)

26
Q

What is loadbearing wall?

A

Support load from above, and cannot be removed but only pierced for doors and other openings (if the top of opening is engineered with lintel or beam).

27
Q

Live Load

A

People and furniture

28
Q

Dead Load

A

Weight of structure itself (beam, column etc)

29
Q

Gravity Load

A

Dead load and live load

30
Q

Lateral Load

A

Wind load and earthquake load

31
Q

Dynamic Load

A

When load is applied suddenly or changes rapidly , ex. Elevator, car moving in garage

32
Q

Impact Load

A

When force is only applied suddenly

33
Q

What is slip joint?

A

Allow building to move slightly without putting pressure on partitions

34
Q

What is core drill?

A

2-4inch round hole drilled through concrete with special hollow drill bit
Used for minor electrical or telephone conduit

35
Q

What is floors of commercial bldgs primarily constructed of?

A

Cast in place concrete
Precast concrete
Concrete or metal decking

36
Q

What system for cast-in-place concrete framing type are easiest to penetrate with small ing for pipes and poke through electrical outlets?

A

Beam and girder system and one way pan joist system
Because there is less reinforcing in the slabs

37
Q

What system is easiest to cut large openings?

A

Flat plate and flat slabs
Possible with waffle slab but difficult and expensive and requires additional support around the cut

38
Q

What is tendons?

A

Post-tensioning steel strands
Cannot be cut

39
Q

Common Residential construction stud size is …..

A

2” x 4” , 16” on center

40
Q

What is lintel?

A

Also called header
When openings for doors and small windows are required, they are framed at top with lintels
Double 2”x4” , 2”x6”, or 2”x8” vertically to act as a beam

41
Q

What is platform framing?

A

For two-story construction
Wood stud placed as a sole plate at bottom and spanned with double top plate at the ceiling level

42
Q

When is glued-laminated members may be used?

A

When stronger members are required in small commercial construction and some residential construction
Also called glulams
Built up from number of individual pieces of lumber, glued together and finish as beams, columns, purloins etc
Unusual shape or larger span are needed

43
Q

What light-weight, efficient, stronger and longer span residential and light commercial construction?

A

I-shaped joist

44
Q

What is LVL?

A

Laminated veneer lumber
Wood member manufactured with individual layers of thin veneer glued together
Used for headers over large openings
Stronger than solid of same dimension

45
Q

What is cricket?

A

Saddle-shaped projection on a sloping roof used to divert water around an obstacle

46
Q

What is designated by for the amount of slope of a roof?

A

Pitch, number of inches of rise for every 12 inch of horizontal projection or run
