Hurricane Charley Quiz:

1) The FBC (Florida Building Code) is administered by the Florida Building Commission and governs the design and construction of residential and non-residential buildings in Florida. The 2001 FBC (effective March 2002) is the applicable building code for the state of Florida.

a) True
b) False

2) When comparing the SBC (Southern Building Code), the FBC, and ASCE 7 in hurricane-prone regions, there are three notable differences that have evolved in these codes and standards that will affect the performance of building. The differences are:

The design wind speed and the averaging time of the wind speed
How and where pressures are calculated on a building
Requirements for debris impact protection

a) True
b) False

3) Exposure is the term used in Florida Building Code and ASCE 7 to define the roughness of the ground surface around a particular building site. Selection of the correct Exposure Category is an important step with the wind load determination process that can alter design wind pressure by more than 15 percent across the building.

a) True
b) False

4) Although the HUD Manufactured Home Construction and safety Standards, 24 CFR 3280, cover the design and construction of the home itself, it is the local jurisdiction that regulates the installation of the home.

a) True
b) False

5) According to the wind zone map in Fig 2-2., Miami would be in:

a) Zone I
b) Zone II
b) Zone III

6) Wind speeds are measured and recorded as sustained and gust wind speeds. For consistency, the report defines sustained wind speed as 1-minute average wind speeds and gust wind speed as 3-second peak gust wind speeds.

a) True
b) False

7) When a building is not designed for internal pressure or if a window or door is broken (breached) such that wind is allowed to enter the building, the building experiences an increase in loads that was probably not designed to handle. Fig 3-2 shows a masonry home with a wood roof structure. Failure of the window in the front wall of the house likely led to pressurization of the house and contributed to the dramatic failure of the roof structure.

a) True
b) False

8) Figure 3-3 and 3-4 show two identical wood frame buildings adjacent next to each other that were in the hurricane path. One building has lost its roof, while the next building is equipped with protective shutters and is undamaged. The reason the second building survived was:

a) The building escaped the pressurization because of the protective shutters.
b) Pure luck
c) Hurricane changed its path

9) The extensive structural damage to the manufactured home in figure 3-8 is the result of 3-second peak gust wind in excess of 110 to 130 mph.

a) True
b) False

10) In Figure 3-9 the wood truss roof failure was caused as a result of :

a) Sheathing loss and lack of bracing at gable end on a pre 2001 FBC un-reinforced masonry building.

b) Earthquake
c) Termite damage in the attic.

11) Figure 3-14 and 3-15 are typical asphalt shingle roof covering loss due to.

a) Hurricane
b) Hail damage
c) Flying debris

12) In Figure 3-20 the cracks at the wooden entry door frame of the house has been caused by:

a) True
b) False

16) Figure 4-5 shows how the roof has blown off over a cathedral ceiling. The cause of roof getting blown away was:

a) Pressurization of the house when the window failed on the windward face during hurricane.
b) Gas explosion in the house
c ) Bad roof design

17) In figure 4-6 the roof decking has failed due to the uplifting load discussed in question 15 and figure 4-4 diagram.

a) True
b) False

18) Figure 4-11 shows:

a) A bad roof job on a newly constructed home
b) A new concrete masonry residence built to 2001 FBC code. The building structurally
performed well during hurricane, although it experienced some asphalt shingle damage.

19) In Figure 4-12 the reinforced masonry wall system is adequately designed.

a) True
b) False

20) In Figure 5-4 the damage to the garage door was caused by:

a) The car backed into the garage door.
b) The suction load in the building’s front envelope.

21) In Figures 5-7 and 5-8 the masonry wall is tilted because of:

a) Bad design
b) Bad construction of non-load bearing wall.
c) The suction pressure loads on the other side of the tilted masonry wall.

22) Figure 5-15 shows:

a) Plastic shutters were not effective during the Hurricane and they were blown off.
b) Plastic shutters were effective during the Hurricane.
c) Those are not plastic shutters

23) Most structural failure observed after the hurricane Charley appeared to be the result of inadequate design and construction methods commonly used before the 2001 FBC; some failures were caused by lack of maintenance or poor condition of the building and its structural elements.

a) True
b) False

24) It was observed that the performance of the manufactured houses against the hurricane was a function of age of the building and the regulations to which the units were designed, constructed and installed. Widespread damage was observed to manufactured housing designed and constructed prior to the 1976 HUD.

a) True
b) False

25) Buildings designed and constructed to resist wind loads prescribed in the 2001 FBC and to the requirements of ASCE 7-98 performed well and showed how improvements to the building codes have been successful in Florida. Structural damages, however is still occurring during code level events such as Hurricane Charley.

a) True
b) False

26) Breach of the building envelope through broken windows, failed doors, or loss of sheathing will not lead to rapid and uncontrolled increases of the internal air pressure in buildings.

a) True
b) False

27) Observations have shown that roof covers and their accessories do not get damaged during hurricane.

a) True
b) False

28) Aggregate roof surfacing does not cause debris damage when aggregate was blown off the roofs by high wind.

a) True
b) False

29) For all roof systems, inadequate attentions were typically given to edge flashing, coping, and gutter/downspout design and installation despite being located in the roof areas subject to the highest wind pressure. Failure of these roofing components often initiated roof membrane lifting and peeling.

a) True
b) False

32) In case #11; It was alleged that Mr. Doe, a Texas PE engineer, altered boundary information on Survey plats for a subdivision that had been prepared by a license surveyor, affixed a copy of the surveyor’s seal to the plats and submitted the plats to county officials for approval without knowledge of the surveyor. The Board reportedly suspended his license for one year and fined him $1000.00

a) True
b) False

33) In case # 15; It was alleged that Jim, the company’s president, designed seven swimming pools and affixed a copy of a Texas Professional engineer’s seal and signature that he had obtained from another source to the plan sheets which were submitted to a city for permitting. Board records did not show that Jim was licensed as a professional engineer in Texas nor that his company had Texas professional engineer as a regular full-time employee. The Board accepted an Agreed Board Order signed by Jim to cease and desist from any and all representations that his company can offer and/or perform engineering services and from the actual performance of engineering services until such time as the company hires a Texas licensed professional engineer as a regular full time employee, and to immediately discontinue the use of the Texas professional engineer’s seal and signature on any and all documents. Jim also agreed to hire a Texas professional engineer to perform after the fact engineering inspections and issue certification reports for the five swimming pools that were permitted and constructed. The company was also ordered to pay a $5000.00 administrative penalty.

a) True
b) False

34) In case #17; John was a registered engineer in:

a) Texas
b) Michigan
c) New Mexico

35) In case #21; It was alleged that Billy signed his name and affixed his Texas Architectural seal to structural, mechanical, electrical and plumbing design plans for renovation of a commercial building. Based upon the size of the building, the structural, mechanical, electrical and plumbing designs were required by law to have been performed by a licensed professional engineer; therefore Billy’s preparation of these design plans constituted the unlawful practice of engineering. The Board accepted a consent order signed by Billy and his attorney agreeing that Billy will not practice engineering outside the exemption listed in the Engineering practice Act and will refrain from making any and all representations that he can offer and/or perform engineering services until such time as he hires a Texas licensed professional engineer as a regular full time employee or until such time as he becomes a Texas licensed professional engineer. Billy also agreed to pay a $1000.00 administrative penalty.

a) True
b) False

36) In case #6; It was alleged that Jim provided professional engineering design services in connection with residential foundation design and exterior wall systems during a period when his Texas engineer license was expired. The Board accepted a Consent Order signed by Jim for a two-year probated suspension of his Texas engineer license contingent upon his payment of a $2000.00 administrative penalty.

a) True
b) False

37) In case #7; It was alleged that Dr. Smith conducted an engineering inspection for his client in December 1998; but did not provide his client with his inspection report until February 2000. This Indicated that he was not acting as a faithful agent for his client and his actions were not in keeping with generally accepted engineering standards and procedures. The Board accepted a Consent Order signed by Dr. Smith for a formal reprimand.

a) True
b) False

38) In case # 24; John-David-Bill, Inc. It was alleged that site grading and drainage plans for two projects were submitted to the city of Brownsville, one set bearing John’s signature and architect seal and the other bearing David’s signature and architectural seal. The size and scope of the respective projects required that Texas licensed professional engineers prepare the grading and the drainage design plans. Board records did not show any of the three were licensed as professional engineers in Texas nor that their company had any regular full time employees who were licensed as professional engineers in Texas. Therefore it appears these individuals unlawfully performed engineering services and their respective plans were an unlawful representation of their company’s ability to offer and /or perform engineering services.
The Board accepted a Consent order signed by the president of the company to cease and desist from practice of engineering and from any and all representations that the company can offer of performing engineering services until the such time as the firm hires a full time employee who is licensed as a professional engineer in Texas. The company also agreed to pay a $2000.00 administrative penalty.

a) True
b) False
