Building Performance and Damage Investigation after 4 Hurricanes


Quiz Questions

1. Which of the following hurricanes struck Florida in 2004?
Charley, category 4
Frances, category 2
Jeanne, category 3
Frances, category 2
Ivan, category 3 + significant flood damage
All of the above
2. Based on observations of wind damage after hurricanes Charley, Ivan and Frances, the most consistent failure was:
Roof covering failure
Mechanical and electrical equipments on the roof
Soffits
Window and door
All of the above
3. South Florida Building Code-both with local amendments-were used to regulate construction in Florida until early 2002 at which time the Florida Building Code (FBC) 2001 Edition was adopted statewide. The FBC is administered by the Florida Building Commission and governs the design and construction of residential and non-residential (commercial, industrial, essential/critical facilities) structures. The FBC 2001 is based on SBC (Southern Building Code) ; however, Florida has completed updates to the 2001 Edition and will release a 2004 Edition of the Code for adoption in July 2005. The 2004 edition is based on the international Building and Residential Codes (IBC and IRC)
True
False
4. In Alabama, which adopts building codes on a statewide basis only for state-owned buildings; jurisdictions have traditionally adopted editions of the SBC, (Southern Building Code) however, the city of Orange Beach adopted the 2003 IBC in the summer of 2004 and the city of Gulf Shores adopted it as an emergency measure after Hurricane Ivan. Other affected communities, such as those in unincorporated Baldwin County, still enforce the SBC.
True
False
5. In overall observations the wood frame houses built in accordance with FBC 2001 and the 2000 IRC performed well structurally, including those located in areas that experienced winds of up to 150 mph (3 second gust) in Charley.
True
False
6. In overall observation of manufactured housing.
There was no significant difference in damage between the houses built pre-1994 HUD standard and after it. (HUD = U.S. Department of Housing and Urban Development)
In high winds the pre-HUD standard homes were mostly destroyed beyond repair. While post-1994 HUD standards homes performed well structurally, these units sustained damages related to building envelope and accessory structure failures.
7. In Concrete Masonry buildings, failure occurred when roof structural systems were inadequately connected to the top of the concrete walls or frame and in URM structures. (URM = un-reinforced masonry)
True
False
8. Steel frame structures were heavily damaged during the hurricane
True
False
9. Significant damage to accessories occurred through out the paths of the hurricanes. Not only the accessory structures themselves fail, but in many cases the failure of the accessory structure led to damage to the primary residence at the point of attachments.
True
False
10. The hurricane Ivan flooded the Florida coastal area. The homes in the costal area that had shallow foundation or shallow embedded pile systems damaged severely during the hurricane Ivan due to erosion and scouring of supporting soil under the foundation.
True
False
11. To minimize damage or prevent failure of older buildings (both residential and commercial), improvements actions that create a continuous load path from the roof deck to foundation must be undertaken. The specific recommendations are included in Matrix #2.
True
False
