Hi gommeqld
The design & codes greatly impact structural & construction considerations for cyclonic and since I have no idea what you are designing, eg Plan image,Size, shape, site contour, split level, access etc,etc it's hard to make specific choices & recommendations. I prefer steel over timber for cyclonic
Contact one steel (lysaght) and ask for someone (rep) who's been there for decades.. I know they have excellent design data, details and info (since they supply the base steel for the cold form section manufacturers), then cross check them with the current codes, a local engineer will need to check the calcs and then certify.
BTW..For construction purposes 3D BIM engineering details and simulations would be perfect for you... but time, cost and finding someone local would be the limiting factors
