Anchor Bolts

The wood mudsill is anchored to the concrete foundation by threaded rods set in epoxy. In most cases the bolts are installed at a maximum of every 4 feet on center and 12 inches from the corner or joint in the mudsill. The purpose of these bolts is to reduce lateral slippage.		 Bearing Plate

Bearing plates give greater bearing surface and help distribute the load at these critical connections.
Sheathing

Plywood sheathing is installed on the inside of the cripple wall. This shear wall acts as a brace to strengthen the cripple wall. During an earthquake, the shear wall resists the lateral movement and the uplift.

10 d nails are used 4 inches to 6 inches on center for perimeter nailing and 6 inches to 12 inches on center for field nailing. The plywood sheathing is generally 1/2 inch 5-ply, and the amount used depends on the size and weight of the building.
Holdowns/Metal Connectors

Holdowns are heavy gauge galvanized steel brackets which secure the cripple wall framing to the concrete foundation to prevent uplift. When holdowns are used with shearwall, the possibility of lateral collapse is greatly reduced.

Holdowns are connected through the mudsill into the concrete foundation by threaded rods embedded in epoxy then bolted to the cripple wall with machine bolts.

Beam and Post Connectors

Galvanized steel post caps are used at the top of floor supporting posts. These steel post and beam connectors increase the ability of the floor supporting posts to resist movement during an earthquake.
Vertical Steel Plates

12" x 12" x 3/16" or 12" x 8" x 3/16" steel plates are bolted to the mudsill and to the concrete foundation with threaded rod embedded in epoxy. These plates perform the same function as anchor bolts, but are needed because of low clearances in areas where there is 24" or less of vertical space between the mudsill and the floor joists.
Framing Anchors or Seismic Ties

Nailed metal framing anchors or seismic ties are used to attach floor joists to cripple wall below. Many types of anchors are used depending upon the situation.




Angle Steel

4" x 4" x 1/4" angle steel connectors are used in low clearance areas also. Where floor joists and beams are accessible in a low clearance area, angle steel connects the floor joists or beams to the concrete foundation helping to resist uplift and lateral movement during an earthquake.

Angle steel is bolted to the floor joist or beam with a machine bolt and also bolted to the concrete foundation with threaded rod set in epoxy.

THE FIVE CONCERNS OF DISASTER PREPAREDNESS
  1. HUMAN SURVIVAL - Water, Food, Warmth, Light, Communication, and Cash
  2. MEDICAL - First Aid, CPR, Trauma, Bloodborne Pathogen, and Training
  3. SANITATION/HYGIENE - Portable Toilet, Waste Liners, Dental Kits, Extra Eye Glasses
    and Medication if necessary
  4. RESCUE AND ESCAPE - Crowbar, Work Gloves, Goggles, Fire Axe/Mask, Dust Mask, Flashlight,
    Battery, Hard Hat, Duct Tape, Danger Tape.
  5. NON-STRUCTURAL HAZARDS - Cabinet, Book Case, Furniture, Water Heater Restraints,
    Electronic Equipment Fasterners, Safety Attachments for
    Wall Pictures, Safety Hooks and cords,
THE MANDATORY FOUR "UNDER THE BED" PREPAREDNESS ITEMS
  1. CROWBAR - To open jammed doors or remove broken gass to escape
  2. SPARE SHOES - Wrap spare shoes in plastic bag. Broken and debris may be present on bedroom
    floor. (Tie bag to bed leg).
  3. LIGHT - Flashlight/working batteries and lightsticks. Secure to bed. With gas smell, use of flashlight
    can cause explosion.
  4. HEAVY DUTY GLOVES - To protect hands from glass and debris.
WATER PRESERVATION AND PURIFICATION

  1. Normal tap water has a shelf life of 6 months. Use (8) drops of Unscented Clorox Bleach per gallon to make water last a year. 1/2 Teaspoons = 5 gallons (or) Use 5 year Water Preserver Products.
  2. Use Water Purification Tablets (Iodine Base), Purification pumps, with natural or chemical filtration, or Sanitizer, (Chlorine Base) to purify water. These products eliminate harmful organisms that grow naturally in water. Shelf life of purification chemicals is from 3 to 5 years.
  3. 5 year shelf life water is purificed, sterile, and vacuumed packed. When 5 year water is void of air and light, life of water becomes dependent on integrity of the container.
  4. Immediately turn off your main water control after the disaster. A broken water line else where can drain water from your water heater and cause a fire, or incoming contaminated water can ruin your existing "in hourse" water heater and toilet tank water supply.
