Federal Emergency Management Agency

1.The mechanical aspects of geological faults are the key factors in understanding the generation of strong seismic motions and modeling their different characteristics.
True
False
2. A normal fault is one of dip-slip type in which the rock above the inclined fault surface moves downward relative to the underlying crust.
True
False
3.During an earthquake, a series of seismic waves shakes the ground in all directions, so that under the critical conditions of water saturation, slope, and soil type, even relatively low levels of ground acceleration can cause a landslide.
True
False
4.Surface Wave Magnitude (Ms) because deep focus earthquakes have no trains of surface waves, only the amplitude of the recorded P wave is used.
True
False
5.Directivity is a term that describes the focusing and defocusing of waves due to the direction of rupture with respect to the direction to a given site.
True
False
6.What does FEMA stand for?
Federal Emergency Material Agency
Functional Emergency Management Agency
None of the Above
7.Shear walls are designed to receive lateral forces from diaphragms and transmit them to the ground.
True
False
8.A notable hazard from moderate to large earthquakes is the liquefaction of water-saturated soil and sand produced by the ground shaking.
True
False
9.A moment resistant frame is the engineering term for a frame structure with no diagonal bracing in which the lateral forces are resisted primarily by bending in the beams and columns mobilized by strong joints between columns and beams.
True
False
10.Structures are commonly designed so that under severe shaking, the beams will fail before the columns.
True
False
11.A possible advantage of external bracing is that often the building occupants can continue to use the building during the retrofit work, which is a major economic benefit.
True
False
12.What does EERC stand for?
Earthquake Engineering Research Center
Earthquake Emergency Research Center
Emergency Engineering Research Earthquake
None of the above
13.Performance based seismic design is used to refer to a design approach that meets the life safety and building performance intents of the code, while providing designers and building officials with a more systematic way to get at the alternative design option currently available in codes.
True
False
14.A performance-based seismic design code format could provide a unified basis for comparison of design alternatives that give decision makers a consistent means of quantifying risk.
True
False
15.A regular building is defined as having a distribution of mass or stiffness of the structure that is non-uniform and is often created in buildings that that have complex space planning requirements or asymmetrical configurations.
True
False
16.What does IBC stand for?
International Building Code
International Building Connection
International Building Configuration
None of the above
17.The dual-system steel-moment frame and passive seismic dampers provide high damping, which significantly reduces the seismic loads imparted to the moment frame.
True
False
18.Seismic isolation is a completely different and reliable concept, in which the building structure is supported on isolation bearings and is effectively separated from the ground, significantly reducing seismic response.
True
False
19.What does figure 7-1 illustrate about?
(Refer Pg 7-7)
Development of Seismic Resisting Systems
Seismic structural systems
Earthquake diagrams
None of the above
20.The simple building code approach to seismic design requires diminishing an acceleration spectra plot by use of an R-value. Elastic design is expressed by an R-value, which is used to modify the acceleration spectral value to a simple seismic design force
True
False
