A combination of brackets and self-locking drawers. Drawer closures should be used to protect the home during seismic events.
Image
A masonry chimney is reconstructed to withstand seismic forces by adding an insert to the existing firebox
Image
A masonry chimney is reconstructed to withstand seismic forces by completely retrofitting the firebox and chimney using light-frame construction on the top of the foundation
Image
A masonry chimney is reconstructed to withstand seismic forces by maintaining the current firebox but replacing the chimney section with a metal flue and light-weight chimney enclosure.
Image
A masonry chimney is shortened and capped at roof level to reduce its chances of detaching in high winds or earthquakes; the fireplace can no longer be used.
Image
A resilient multifamily building in Puerto Rico constructed of concrete on a raised slab foundation with a hip roof design for wind resistance and deep overhangs and permanent awnings to keep sun and rain off windows.

Image
Nailing and ridge ventilation for roof sheathing used as a structural diaphragm in high-wind and seismic hazard areas.
Image
Plywood or OSB shear wall panels help the wind to resist the compression, tension, and shear forces of high winds and earthquakes
Image
Right - Braced wall line spacing is correctly calculated for determining wall bracing in accordance with the IRC.
Image
Right - Engineered portal frames are used for wall bracing to resist wind and earthquake loads.
Image
Seal the roof deck as follows: Sweep roof decking, tape seams, and cover underlayment or roofing felt as shown.
Image
Self-locking drawers and cabinets can be installed to protect against damage from seismic events.

Image
Types of brackets recommended for use in securing cabinets and drawers to the wall of the home.
Image
When installing fasteners in roof sheathing, common mistakes include using the wrong size fasteners, missing the framing members, overdriving nails, and using too many or too few fasteners.
Image
Wrong - Framing a dormer using only toe nailing and end nailing is not acceptable in areas subjected to high winds, hurricanes, or earthquakes.
Image
Wrong – The cabinets and drawers were not outfitted properly with mechanical or self-locking latches, causing them to swing open and spill their contents onto the floor.
