RE: History of conventional wood framing- update

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Yep,  a higher standard of damage control housing construction may be a good

BUT, the benefit/cost and probability of occurrences of such damaging
earthquakes does not produce favourable outcomes.  To get $$$ benefit there
needs to be casualties costs and significant loss of function costs.   This
is not true for wood frame housing construction, providing that basic
design/construction details are attended to.

A government directed housing insurance scheme addresses the catastrophe
cost problem in New Zealand, where insured properties throughout the land
share the risk. There is 90% insurance coverage, and only part of the
country is expected to suffer damaging earthquake within certain time
