Design and Construction of Safe Room and Shelter Against Terrorist Attack


Quiz Questions

1.Bacteria are small free-living organisms that reproduce by simple division and are easy to grow. The diseases they produce often respond to treatment with antibiotics
True
False
2. ________________are poisonous substances found in, and extracted from, living plants, animals, or microorganisms; some toxins can be produced or altered by chemical means.
Toxins
Aerosols
3.What does FEMA stand for?
Federal Emergency Management Agency
Federal Emergency Management Association
Federal Emergency Management Attacks
None of the above
4.A standalone shelter is considered a separate building (i.e., not within or attached to any other building) that is designed and constructed to withstand the range of natural and manmade hazards.
True
False
5.An ___________________is a specially designed and constructed room or area within or attached to a larger building that is designed and constructed to be structurally independent of the larger building and to withstand the range of natural and manmade hazards.
Internal shelter
Laboratory
6.Shelters should also be located inside areas known to be flood prone, including areas within the 100-year floodplain.
True
False
7.For a standalone shelter, many sites will be constrained or site limited for underground, and an aboveground structure may be the only feasible alternative. For these sites, the siting considerations include:
Outside the floodplain
Separation distance between buildings and structures to prevent progressive collapse or impact from collapsing elements
Separation from major transportation features (road, rail)
Access to redundant power and communications capabilities
All of the above
8.What does ASHRAE stand for?
American Society of Heating, Refrigeration, and Air-Conditioning Engineers
American Society of Heating, Reviewing and Air-Conditioning Engineers
American Society of Heating, Reviewing Agency Engineers
None of the above
9.The parameters that primarily determine the characteristics and intensity of blast loading are:
Weight of explosives
Type of the explosives
Distance from the point of detonation to the protected building
All of the above
10.Shear is a brittle mode of failure and primary members and/or their connections should therefore be designed to prevent shear failure prior to the development of the flexural capacity.
True
False
11.The ratio of a member’s maximum inelastic deformation to a member’s elastic limit is a measure of its__________________.
Ductility
Redundancy
12.What does figure 2-7 illustrate about?
(Refer Pg 2-13)
Effects of uplift and load reversals
Ductile detailing of reinforced concrete structures
13.Floor slabs are typically designed to resist downward gravity loading and have limited capacity to resist uplift pressures or the upward deformations experienced during load reversals that may precipitate a flexural or punching shear failure.
True
False
14._____________________involves both the blocking of sightlines to conceal the occupants and the use of ballistic-resistant materials to minimize the effectiveness of the weapon.
Ballistic-resistant design
Forced entry
15.Reinforced concrete is a composite material in which the concrete provides the primary resistance to compression and shear and the steel reinforcement provides the resistance to tension and confines the concrete core.
True
False
16.The building’s facade is its first real defense against the effects of a bomb and is typically the strongest component that will be subjected to blast pressures.
True
False
17.A CBR safe room protects its occupants from contaminated air outside it by providing clean, breathable air in some ways:
By trapping air inside the room and minimizing the air exchange (an unventilated safe room)
By passing contaminated air through a filter to purify it as it is supplied to the room (a ventilated safe room)
a & b
None of the above
18.The addition of air filtering improves the protection a safe room provides, although there is limitations as to what gases can be filtered.
True
False
19.There are two general approaches to closing the intentional openings in transition to the protective mode. The first is to use hinged covers mounted within the safe room. The second is to use automatic dampers, particularly in ducts for supply, return, and exhaust.
True
False
20.An air-handling unit can be operated in a safe room in the protective mode only if the unit and its ducts are fully within the safe room.
True
False
