1. What is wind mitigation? Building in the path and pattern of the sea to shore for tropical storms Specific activities to strengthen your home. 2. The primary damages from hurricanes are wind and water intrusion1. Water, as rain directed by varying wind directions, enters homes through gable ends soffit vents poorly sealed windows and doors All of the above 3. A sealed roof deck: Prevents water intrusion if shingles are blown away during storm Provides addition insulation to make your home more energy efficient Both of the above. 4. Reinforcing your foundation to wall, floor to wall and walls to roof _______ create a stronger load path to the structure of the house to resist high wind forces during storm. Does not Does 5. Gables that are taller than ______ will benefit from reinforcing the framing and bracing the top and bottom of the gable. 4 ft 6 ft 10 ft 6. Shatterproof glass windows are expensive, _________ the need to shutter before a storm. But eliminate And do not eliminate 7.
For existing garage doors additional bracing can be applied. Hurricane- rated garage doors are ______ and often in a storm power is lost, so electric openers won’t work.
Heavier Lighter Made out of wood 8. 8 d ring shank nail can be described as: A nail that is 8 inches long A ringed shank (grooves in the nail) provides more secure grip and prevent forces pulling the nails out of the wood. 9. For the underlayment, the Institute for Business and Home Safety recommends a code compliant 30-pound ASTM D226, Type II underlayment and attached using annular ring or deformed shank roof fasteners with minimum 1-inch diameter caps. Metal caps are recommended where wind speeds may exceed 140 mpg. True False 10. A continues load path, in layman terms, is the function of your house as whole, not components of a foundation, walls and a roof. The load of a hurricane force that is coming to your path 11. Many varieties of connectors are manufactured to meet the wide variety of connections that could exist between the rafters and the walls. Every connection, every joint must be secured. Local building departments generally require permits which will leave the soffits uncovered until a post-inspection of work is completed. True False 12. Upper wall to lower wall connections exist with a multistory home. This connection _____ required for single story homes. The connector/hurricane strapping for the upper wall to lower wall connection is a solid steel connector that requires the removal of siding on existing homes. Is Is not 13. Wind resistant doors are generally heavy, solid doors. The most obvious feature of wind resistant doors is that it _______. Wind resistant doors also have at least three and generally four mounting brackets with screws that are 2 1/2 to 3 inches long. This will ensure the door is connected to the door frame as well as the wall framing behind the door frame. Opens out Opens in 14.
Figure 23 is a example of roof wall connection. The failure of roof-to-wall connections results in enormous damage to a building, in most cases causing a loss that approaches the _________ of the building and its contents.
Half insured value Full insured value One third insured value 15. Foundation failures that have occurred in past hurricanes have almost always been associated with the action of storm surge and waves and not wind loads. However, the connections for buildings on piers need to be adequately designed and periodically inspected for corrosion. True False 16. Roof deck attachment during a hurricane is critical to the survival of the building (Figure 5). Once a building looses one or more pieces of roof deck, the losses increase ______________ due to the vast amount of water that enters the building. Exponentially Moderately 17. One of the most important connections in a house is the roof-to-wall connection. The critical loads on the roof are _____________ pressures that produce uplift forces on the roof. Negative (suction) Positive ( Compression) 18. Toe-nailed roof-to-wall connections, a relatively common building practice in the past, are especially vulnerable to failure (Figure 6). Properly installed hurricane straps that connect the roof truss to the wall frame generally provide for adequate resistance to ________________. Uplift roof failures Compressed roof failure 19. Houses with gable ends are also vulnerable to gable end wall failures (Figure 7), although these failures are not, on average, large contributors to loss. True False 20. The shape of the roof influences the aerodynamic loads experienced by the roof covering, roof deck, roof framing and connections. Figure 8 illustrates gable and hip houses at Navarre Beach (on the same street), following Hurricane Erin in 1995. Gables, on average, _______________ hips due to roof shape aerodynamics and the lack of roof-to-wall connections on all 4 sides of the house. Do not perform as well as Perform better than
