New Code for Post & Pier ?

[randomq]

Any opinions on sheet metal the thickness of metal roofing as siding?

Would it have enough sheer factor on the corners of a traditionally framed building, without needing plywood underneath?

All plastics including Legos slowly ooze out toxic gasses into the atmosphere.

The Chinese "3D printed" buildings are made of concrete.

Wood is a poor inventment.

Which opinion has been made abundantly clear. As I live on a mafia-controlled island, my house will be made of wood -- not my first choice, but nor do I have the time/money to fight County and build a house.

HPM uses it to side their buildings.

The metal roofing I have seen has very little, if no shear value. I'm sure HPM is taking advantage before the "newer" Code is adopted and actually using the seismic zone tables as prescribed. It is the ribbing that destroys the shear in the panel, as the shear stresses would follow the ribbing, instead of spreading and dissipating in the nail pattern to framing that a smooth panel would provide, in my opinion.
Take standard wood siding called "T1-11", or the vertical cut siding that comes in 4x8 sheets. The half inch thick version fails miserably because the kerf cuts to make it look like individual boards are too deep into the thickness of the plywood, and tears itself to shreds following the vertical cuts, where the 5/8" version passes shear test with no damage. Both were "nailed off" 6 inch spacing on the edge, and a 12 inch pattern in the "field" of the panel.
In my building, and inspection experience I would use 1/2 inch structural plywood, not your normal on a shear wall to perform in a manner In Which I expect it to do if required. I have not seen where HPM installs metal siding in the construction process, so do not know if plywood is underneath the material in the corners.
But remember, nothing, I repeat nothing one can do to make it "earthquake, tsunami or hurricane" proof that it will be unharmed in an event. The design is merely to keep the house together enough so you can get out, whether it be walking, or crawling.
The "tsunami safe" room to me is to me nothing more than a tomb to find your family to make the coroners job easier. It may stay together with you and your loved ones in it, but will more than likely covered in 20 feet of debris and mud, or bobbing 5 miles out in the ocean. Oh joy.

"tsunami safe" room = A boat Tink : ) + yeah hope it stays on surface. Needs drilling tools inside.

The wood mafia seems to be in charge. I am having to get engineering on single story plans. The issue with steel is the engineer the county hired doesn't know steel at all. He admits it. That's a rather uneducated engineer.

Steel is not a rarity in modern construction... it is a mainstay. As much as they pretend to like wood frame the fact is that wood frame has become so distrusted in seismic engineering that wood has become an infill between steel Simpson connectors.

The engineer the county hired is from L.A. Wanna guess what no longer exists in L.A.? Affordable housing.
That is our future. Housing for the wealthy only.

Frankly the way the building department is dealing with this looks like restraint of trade to me. That is illegal. Requiring something from one business (steel framing) that they don't require from a competitor. If they aren't educated about steel they shouldn't be asking the public to pay for their education. They should bone up on the subject on their own dime.

Agreed Rob.
I was really shocked by the ignorance being applied. Not much we can do about, eventually someone will step up with a wad of cash and take the department to court over the matter.

Only if they're planning to leave the island...

[kalakoa]

There is no great conspiracy to deprive Hawaii of non wood alternatives that are superior to wood, this is just a matter of market forces at work.

Market forces only work correctly on a level playing field, eg, "competition on merit". When the local permitting authorities aren't competent to evaluate wood alternatives, the market forces become irrelevant.

Seen it done here already. Just a matter of time, unless they correct the conflict between their unwritten policy and the written code.

[Tink]

A Federal Grand Jury does not recognize unwritten policy, and whether or not the Building Official is accredited through the International Conference of Building Officials (ICBO), as well as the Department following the rule of only 2 Code books behind (2010 version). Current BO is probably skating on "temporary", as I believe he has Civil Engineering certtficates ( dirt and roads).
Good luck getting an inquiry due to the "network" tho....
