Improving Cyclone, Earthquake & Tsunami Resistance

Two levels of improvement are applicable.

1/ Anchor points with temporary tie ropes. The anchor points are permanent and may be constructed cheaply. The tie ropes may be positioned and tightened at the commencement of the cyclone season (if not already in place). This is a cheap “quick fix”, but is reasonably unattractive and provides only modest improvement.

2/ Additional roof fixings and cyclone washers, roof framing anchors, timber diagonal bracing, steel diagonal bracing and/or sheet bracing. These are permanent structural features that should be installed as part of the construction of new buildings, but are often missing. They may be retro-fitted to existing buildings.
