Learn from the Past, Build for Tomorrow
Today’s building codes coupled with advances in wood science and building technology have expanded the options for wood construction. Sound design and construction of tall mass timber buildings, based on international research and compliance with code to ensure life safety, can help make communities more resilient during and after seismic and high wind events. By embracing the benefits of wood as a sustainable building material, architects and engineers can tap the virtually unlimited design possibilities of wood material, while delivering buildings that will perform well for families, communities and the environment for centuries.
"Building Safety Month provides a great opportunity to promote building homes that are stronger and more resilient to natural disasters. Through our safestronghome.com website, Simpson Strong-Tie works to educate homeowners about ways that they can protect their home from the forces of Mother Nature."
Jeremy Gilstrap, Simpson Strong-Tie Vice President of Engineering
Precast concrete, manufactured in a controlled environment, inherently provides a high level of resiliency, mostly due to its strength, mass, and durable nature. Resiliency refers to the ability of a structure to withstand extreme events such as hurricanes, tornados, earthquakes, explosions, and fires.
WEEK THREE // May 16–22, 2016
Prepare Your Family
Making sure your family is prepared for any natural disaster is important. Below are some of the steps you can take to prepare your family and protect your home from natural disasters. Your actions can ensure that no matter what Mother Nature brings, you, your family and your community will be resilient.
- Develop a family disaster plan that includes a list of food and water supplies needed for each member of your family and supplies for your pets. Make copies of important documents like insurance policies, the deed to your home, and other personal papers, important phone numbers and a home inventory. Create a checklist of important things to do before, during and after a disaster.
- Review your evacuation route and emergency shelter locations with your family. Options for evacuation would include staying with friends and relatives, seeking commercial lodging, or staying in a mass care facility operated by disaster relief groups in conjunction with local authorities.
- Taking shelter is critical in times of disaster. Sheltering in place is appropriate when conditions require that you seek protection in your home, place of employment, or other location where you are when disaster strikes.
Review your plan regularly. If you make changes that affect the information in your disaster plan, update it immediately.

Protect Your Home
The power of these natural disasters can be overwhelming. While you can't necessarily stop natural disasters from happening, there are steps you can take to increase your home's chance of survival, even in the face of the worst Mother Nature can dish out.
Build to Code
Although you have little control over the occurrence of hazards in your community, mitigation efforts such as building code adoption and enforcement is one of the strongest strategies jurisdictions can take to protect a community against the effects of natural hazards. Mitigation increases occupant health and safety during a disaster, protects the local tax base, ensures continuity of essential services, and supports more rapid recovery from disasters.
The development and widespread adoption of building codes is beneficial in that it has created a uniform regulatory environment in which design professionals and contractors are held to a set of standards adopted by and applicable to the jurisdiction in which they work. More importantly, building codes provide you, your family, and your community protection in the event of a natural disaster.
What are Building Codes?
Building regulation in the United States began in the late 1800s when major cities began to adopt and enforce building codes in response to large fires in densely populated urban areas. The primary intent of early building codes was to reduce the fire risk, but over time, their scope has broadened. Today, building codes are sets of regulations that address structural integrity, fire resistance, safe exits, lighting, ventilation, and construction materials. They specify the minimum requirements to safeguard the health, safety, and general welfare of building occupants.
The International Code Council (ICC) family of codes covers all aspects of construction. Specific products of interest may include:
If the earthquake occurs in a populated area, it may cause deaths, injuries and extensive property damage. Here are some helpful tips to prepare your family and protect your home.
- Plan and hold earthquake drills for your family. To learn more about planned earthquake drills in your area, visit http://www.ShakeOut.org
- Identify two ways to escape from every room in the home.
- Keep a flashlight and sturdy shoes by each person's bed.
- Select a safe location away from the home where your family can meet after evacuating.
- Have an earthquake kit containing water, food, medicines and other necessities for at least three days
- Make sure your home is securely anchored to its foundation
- Strap water heaters, appliances and TVs to wall studs.
- Anchor bookshelves, heavy furniture, appliances and televisions to wall studs.
- Secure pictures, mirrors and ornaments to the wall with appropriate fasteners.
- Know where and how to shut off electricity, gas, and water services.

Devastating floods occur throughout the U.S. every year. Ninety percent of all presidentially declared natural disasters involve flooding. Flooding is usually divided into two categories: flash flooding and river flooding. Both can cause death, injury and property destruction. If you are building or retrofitting your home consider these recommendations:
- Elevating your home above the base flood elevation (the elevation associated with the "100-year flood") is the best method of protecting your home, and is a requirement for new homes. The term “100-year flood” is misleading. It is not the flood that will occur once every 100 years. Rather, it is the flood elevation that has a 1 percent chance of being equaled or exceeded each year.
- Wet flood proofing your home allows flood water to flow through the structure. An example of wet flood proofing is installing flood vents that create permanent openings in the foundation.
- Dry flood proofing your home prevents floodwaters from entering the building. An example of dry flood proofing is installing new brick veneer over asphalt coating and applying polyethylene film over existing walls.
- Construct non-supporting, break-a-way walls designed to collapse under the force of water without causing damage to the foundation.
- Use flood damage-resistant materials below the base flood elevation.
- The best place to start is with a Do-It-Yourself Wind Inspection to find out what is ok with your house and what needs attention.
- In a high wind event anything can become a dangerous flying object. Take a day to make your landscaping more hurricane resistant.
- Check to see if your gutters are clear of leaves and other debris to prevent flooding.
- Improve your roof's resistance to uplift by applying a 1/4 -inch bead of caulk of along the intersection of the roof deck and the roof support element (rafter or truss chord) on both sides with a caulking gun.
- If your home is not protected by impact-resistant windows and doors or impact-resistant shutters or panels, consider building your own temporary emergency panels.

Tornadoes and High Winds
A properly built, high wind safe room protects your family from the most intense tornadoes and hurricanes and can be incorporated into a planned build or renovation to create a multiuse space in your home, adding to its value. FLASH urges homeowners to "Give an Ordinary Room an Extraordinary Purpose" by building or retrofitting interior spaces in their home to safe-room standards.
- Tornado safe rooms are designed to withstand winds up to 250 miles per hour, and offer lifesaving refuge for families in the path of high-wind events like tornadoes.
- A safe room designed to meet standards set forth by the National Storm Shelter Association, the International Code Council and FEMA and will stand up to the most intense tornadoes and hurricanes.
- Safe rooms can be located anywhere on the first floor of your home, in a basement or outside. A safe room can double as a closet, bathroom, laundry or even an outdoor room like a garden shed or pool house.
- Preparing for Tornados and High Winds by Simpson Strong-Tie
Each year, thousands of acres of wildland and many homes are destroyed by fires that can erupt at any time of the year. Wildfires spread quickly, igniting brush, trees and homes. You can protect your home by following these tips.
- Prevent wildfire damage by developing a defensible space in your landscaping by clearing at least 30 feet around your home, or 50 feet around your home if you reside in a heavily wooded area.
- Plant fire-resistant, native vegetation and remove any dead or dying trees. Properly prune shrubs, and trim tree branches so they don't extend over a roof or near the chimney. Mow your grass and control the height and spread of ground covering vegetation. Keep plants at least 12 to 18 inches away from the house.
- When putting on a new patio deck, build from fire-resistant materials. On new and existing decks, create fire barriers around the deck base and clear vegetation at least 100 to 300 feet downhill from the deck base.
- Install only burning-brand, exposure rated (Class A, B or C) roof assemblies using materials such as asphalt shingles, slate or clay tile or metal roof coverings.
