Building Performance and Damage Investigation after Hurricane Katrina


Quiz Questions

1.One of the recommendations to Louisiana and Mississippi coastal areas after Hurricane Katrina was to adopt 2006 IBC and IRC codes or 2006 NFPA 5000, for all jurisdictions in each state.
True
False
2. BFEs (Base flood elevations) are the minimum elevations to which the lowest floors, as defined by the NFIP (National Flood Insurance Program), are required to be elevated
True
False
3.The SFHA (Special Flood Hazard Areas) zones and BFE (Base Flood Elevation) are critical factors in determining what building requirements apply to a structure.
True
False
4.In Louisiana, many buildings were constructed behind levees that were intended to protect them from the 100-year flood. SFHA (Special Flood Hazard Areas) zone designation for areas protected by the levees, are based on the certification by the levee owner, that the levee provides protection from the base flood event in onformance with 44 CFR65.10.
True
False
5.The ICC (International Code Council) code include the IBC (international Building Code), the International Residential code (IRC), the International Existing Building Code (IEBC) and a series of codes for mechanical, plumbing, fuel, gas, and on-site sewage installations.
True
False
6.In general most of the residential buildings in the city of New Orleans did not experience structural damage due to hurricane winds, but were impacted by high flood levels. The flooding experienced by most buildings was slow-moving, after the floodwalls failure the flood water stayed in New Orleans for 2 to 3 weeks.
True
False
7.In Figure 2-1, the reasons for the successful standing of the house compared to the buildings around it that have been destroyed by Hurricane Katrina are.
It is well elevated, where adjacent buildings’ foundation was not high enough.
Its pile embedment was deeper and sufficient compared to its adjacent structures.
All of the above.
8.Figure 2-3 is typical building failures when surge and waves exceeded pier foundation height.
True
False
9.Figure 2-5 is a typical example of some of the buildings on pier foundation that floated off during the flood after the hurricane.
True
False
10.The house bellow figure 2-6 is an example of a well elevated house that survived the flood depth associated with Hurricane Katrina. The red dotted line is the estimated water line associated with Hurricane Katrina
True
False
11.Some of the historic buildings in Louisiana that were built on higher elevations and taller piers (an architectural choice, not a requirement when the buildings were constructed in 1900) sustained minimal damage during the flood associated with Hurricane Katrina
True
False
12.The predominant structural damage to the wood frame structures, residential and commercial, was failure of the wall and roof elements.
True
False
13.Little structural damage was noted to most buildings constructed with reinforced concrete frames. Extensive structural damage was observed to un-reinforced masonry buildings.
True
False
14.On pre-engineered metal buildings such as, storage facilities, aircraft hangers or warehouses, most of the damage was between the metal roof panels and their supporting purlins, or between the purlins and the steel frames. (fig 2-16)
True
False
