A

Less than 1 Hz

24

A building is considered Rigid if the natural frequency is _______

A

Greater than 1 Hz

25

What are the three options for evaluating wind loads?

A

Simplified Procedure, Analytical Procedure, and Wind Tunnel Procedure

26
Q

What is the internal pressure of an enclosed building?

A

+/- .18

27
Q

What is the first type of seismic wave to arrive in the event of an earthquake?

A

A compression wave

28
Q

What is the most concerning type of seismic wave?

A

A Shear wave

29
Q

The intensity of any earthquake is based on what?

A

Damage and other observed effects on people, buildings, and other features.

Modified Mercalli Intensity Scale (12 levels of intensities)

30
Q

The measure of an earthquake strength is ______.

A

Magnitude

Measure by Richter Magnitude Scale

31
Q

Minor Earthquakes are categorized by what numbers on the modified mercalli scale?

A

I - VI

Not felt through slight damage.

32
Q

Moderate Earthquakes are categorized by what numbers on the modified mercalli scale?

A

VII & VIII

Damage in some buildings through Considerable Damage in most

33
Q

Major Earthquakes are categorized by what numbers on the modified mercalli scale?

A

IX - XII

Damage in majority of buildings through total damage

34
Q

What is another term for Displacement?

A

Distance

35
Q

What is Velocity?

A

Rate of Change in Distance

36
Q

What is Acceleration?

A

Rate of Change in Distance of a period of time

37
Q

What is Damping?

A

Process by which vibration diminishes in amplitude

38
Q

Which is better…
1 story building on rock
or
20 story building on rock

A

20 story building on rock- There has to be movement somewhere, the building or the soil. A 20 story building will move more than a 1 story building so it can be on rock.

39
Q

Which is better…
1 story building on deep soil
or
20 story building on deep soil

A

1 story building on deep soil- There has to be movement somewhere, the building or the soil. A 1 story building won’t move much so the soil needs to be flexible.

40
Q

A live load reduction can be taken on structural elements only if they support a tributary area of _____ square feet or more.

A

150

41
Q

Which of the following are considered impact loads?

  1. Elevators and Elevator machinery
  2. Vehicles on garage floors
  3. Stadium and arena bleacher loading
  4. Floor hangers supporting machinery
A

Elevators and Elevator Machinery, and Floor Hangers supporting machinery

42
Q

T/F Horizontal shear stress is always equal to vertical shear stress

A

True

43
Q

A framing system in which the joints are moment connections and allow for unimpeded movement throughout the bays is called a?

A

Vierendeel Frame

44
Q

The ability of an element or system to resist gross deformation is known as?

A

Stability

45
Q

Name the first four soil site classes (A-D)

A

A- Hard Rock
B- Rock
C- Very dense soil or soft rock
D- Stiff Soil

46
Q

What is the best soil class that can be assumed without a geotechnical engineering report?

A

Site Class D- Stiff Soil

47
Q

The ability of a system or element to dissipate energy beyond the elastic limit is ____

A

Ductility

48
Q

A measure of a systems ductility over strength is called _______

A

Response modification factor

49
Q

What are the two design methods for loads that do NOT factor loads?

A

Allowable Stress Design and Allowable Strength Design

50
Q

What are the two design methods that factor loads?

A

Strength Design Method and Load and Resistance Factor Design.
