Hi Ken;
To me an Alaskan slab is a poured concrete slab with thickened edges. This "monolithic pour" is the entire foundation and does not need footings underneath. We use these slabs some here in the frozen north so I am sure they would be even more reliable there the ground does not freeze four feet deep as long as the soil is stable. High quality anchors embedded in the concrete are important to keep the frame tied down. Your local building code enforcement officer may be friendly and would answer detailed questions.
Good luck;
Jim
Jim,
Maybe I was not clear in my first post? I am planning two stories TF structure with 2nd floor containing a floor joint for me to live upstair and will be using Queen Post design as a bent. I do not think that a simple Alaskan Slab will support the structure itself. Please keep in mind that the code in this area require to support 200MPH wind load. All the structures must be bolted down using the anchor. I imagine that the 4" concrete slab will suddenly crack easily under the wind load stress and will collapse? That is why I was seeking professional (or near there) opinion on the 3' X 3' X 3' footing
under each post area. The footing would act as an underground concrete pier and joined with the 4" slab.
The local building inspector is nice and friendly, but he doesn't know very much of Timber Frame engineering he said I had one of two options: 1) Get a friend with building license and use his license to build it or 2) Get engineer stamp and he will let me build it as 'Self'. Log home and TF is a very rare structure around here anyway.
