E – 1358 Basic Principles of Protecting Residential Structures From Wind
Intended Audience: civil and all engineering areas
PDH UNITS: 2
This course introduces the basic principles of protecting residential structures from high winds. The content of this course is a compilation of several FEMA documents pertaining to wind protection of residential structures. A team of experts examined homes that had failed and homes that had survived damage from Hurricane Andrew. It has been found that once high winds penetrate the building envelope (outer shell) of the home, the likelihood of significant structural damage to the home greatly increases. It can be concluded that protecting the building envelope increases the chances of the home surviving the storm with less damage. The experts identified common areas of weakness – the roof, the doors, windows, garage doors (where applicable), roofing systems, and external insulating finishing systems (EIFS). Gable roof systems were also found to be more likely to suffer damage during a high wind event. Each area of weakness identified also includes simple and effective remedies. Emphasis is made that residents should not avoid or delay evacuation based on implementing the remedies in this course.
This course demonstrates that seemingly minor areas of weakness could provide a path for high winds to enter the home and cause serious damage. The course presents remedies for the most common weaknesses and the highest priority structural preparations for high winds.
At the successful conclusion of this course, you’ll be able to identify and discuss:
- Awareness that protecting the home does not decrease the urgency to evacuate
- Awareness of the importance of protecting the building envelope
- The common areas of weakness of residential structures during storms with high winds
- Remedies for the common areas of weakness of the structure
- Preparation of the home for high winds
- Preparation of the property around the home for high winds
- The role that regular inspection and maintenance of the home can have in making the home more resistant to high winds
