Re: [DIY] foundation destroyed by quake??

 

I was at home in Ben Lomond at the time (PTO or home sick).
Pier and post foundation that got pretty messed up. We eventually
had to jack up the house and dig/pour a perimeter foundation.
Still it flexed rather than collapsed completely.
After the quake, there was 3 inches of variation in different parts of the floor,
for the 900 sq ft house I was living in. Forget playing marbles inside ;-)
Brick chimney came partially down. I spent the next couple of days
helping neighbors pull more brick down on houses in the neighborhood.

The house site I'd already mentioned was under construction, just the foundation
had been poured. The folks trying to do the job were an owner/builder,
probably without full permits, and were from the midwest (no previous knowledge
of quakes or quake codes).  So yeah, it was  easy to see the foundation damage after the fact.

Each quake we learn a little more, refine the codes, the weaker
structures are removed.  Yes the codes are not a guarantee
of no damage, but improve your odds of having less damage, or perhaps
not being crushed by the house falling around you.

Now if we get one of those 8. quakes up in Washington state like they
seem to think have happened in the past, all bets are off.  Trees survive
ok, all the man made structures, well, we will see.

Epicenter was outside Soquel, northeast of Santa Cruz, 6.9 at 5_04 PM,  world series just got
started....I was in my hammock with portable TV!! LOL...and friends lived in Boulder Creek.

I looked at property there and saw several homes damaged but all
the bare foundations Steve and I saw had rebar sticking out...like
a war zone.....kinda very unusual
to pour without rebar..even 50 years ago..

The real damage was in downtown Santa Cruz..almost every building
was down (and plenty of rebar also!!)..

I think all this quake code
and proofing certainly helps..but unless you do what Frank Lloyd Wright
did in Tokyo we in California will always face devastation in quakes over
5.5,..my office was cracked and destroyed in Livermore by a 5.6 years
ago...

anyway..
! thanks for the respond
