Chap 5 Basic Building Construction

Question 1

Key factor in fire performance of wood. Wood also carries its load by this.

Answer 1

Mass

Question 2

2nd most important point to remember in wood frame construction is what?

Answer 2

Connection method used to hold structural members together

Question 3

An older type of wood frame construction in which the wall studs extend vertically from the basement of a structure to the roof without and fire stops

Answer 3

Balloon Frame

Question 4

A type of construction in which each floor is built as a box. The framing in each level is set on a sill plate and runs the height of one floor.

Answer 4

Platform frame.

Question 5

Framing method that uses post (vertical members) and beams ( horizontal members) to create a load bearing frame connected by rigid points. Used in barns and farm buildings and in some commercial buildings.

Answer 5

Post and Beam

Question 6

A framing method that uses heavier beams that are spaced much farther apart than the traditional 16 inches. It is used in modern construction.

Answer 6

Plank and Beam

Question 7

Do not put anyone on top of, underneath, or at the sidewalls of this type of roof.

Answer 7

Bowstring truss roof

Question 8

This type of construction is ofter times referred to as Mill Construction

Answer 8

Heavy timber

Question 9

Heavy timber uses large wooden columns larger than and can be used for buildings up to how tall?

Answer 9

Larger than 8x8 and buildings up to eight stories tall/

Question 10

The hazards with Heavy timber structures?

Answer 10

Walls and ceilings are typically unfinished and lack any real fire protection.

Connection points are an important factor for heavy timber

Question 11

This type of construction is composed of masonry load bearing walls with wood joisted floors and a wood roof?

Answer 11

Ordinary Construction

Question 12

Building materials for load bearing walls in Ordinary Construction?

Answer 12

Brick, concrete block, or both

Question 13

Joist with a 30 degree cut on them? What are they and where are they found?

Answer 13

Fire cuts

Sits in pocket on exterior wall to, collapse downward and saves exterior wall in case of fire.

Question 14

Used to spread a load between two or more structural members. Indicated by star or other decorative device on the exterior.

Answer 14

Spreader

Question 15

This type of spreader is a rod or cable that runs parallel to the joist and ties the walls together to increase the stability of either or both walls.

Answer 15

Type 1 spreader

Question 16

This type of spreader uses Tensile members, rod or cable, that run perpendicular to the joists and tie the fire three or four floor joists to the wall. These members may be part of an original design of heavy timber building, or they may be added to a building to support a weak wall.

Answer 16

Type 2 spreader

Question 17

This type of construction employs building materials that will not add fuel to the fire but can suffer from the effects. Exposed steel trusses and iron beams can elongate and fail during fires.

Answer 17

Type 2 Non combustible

Question 18

Most common method for building the roof structure on non combustible construction?

Answer 18

Metal decking build up of different materials.

Metal deck>insulation material>then alt layers of felt and tar>light gravel

Question 19

When walking on flat roofs, where should you walk and why?

Answer 19

Along the side next to the wall, roof is better supported and less likely to collapse under your weight

Question 20

Rule of thumb for the expansion of steel.

Answer 20

1 inch for every 10 feet at approximately 800f

Question 21

This type of construction has the most inherent fire safety factors associated with both the building material and the building techniques.

Answer 21

Type 1 fire-resistive

Question 22

Top and bottom members of truss

Answer 22

Chords

Question 23

Inside members of truss

Answer 23

Web

Question 24

Trusses are tied together with connecting members called?

Answer 24

Ties

Question 25

Connection points inside web, Not talking about gussets

Answer 25

Panel Points

Question 26

Most dangerous type of truss

Answer 26

Bowstring truss

Question 27

Most common truss for roof construction?

Answer 27

Peaked roof truss

Question 28

How far apart are trusses placed? How are they held in place?

Answer 28

16 to 24 inch on center.

Plywood roof material.

Question 29

Besides toe nailing, way that trusses are connected to wall?

Answer 29

Metal clips, hurricane ties

Question 30

This type of truss is used for both roofs and floors. Can be either wood or steel. Top chords and bottom chords run parallel to each other.

Answer 30

Parallel Chord Truss

Question 31

The void space and potential problem with parallel chord truss.

Answer 31

Interstitial space.

Question 32

These have helped the building industry span larger open distances with load bearing ability at a lower cost.

Under fire conditions, they can begin to delaminate, reducing strength and mass of the beam.

Answer 32

Laminated beams and engineered I-beams
