Any building damaged by earthquake suffering from any or all of
the following conditions or defects shall be determined to be unsafe as defined
in ORS 455.010, if life, health,
property or safety of the public or its occupants are endangered:
(1) The stress in any materials, member or
portion thereof, due to all dead and live loads, is more than one- and one-half
times the working stress or stresses allowed in Oregon Structural
Specialty Code (OSSC) or One and Two Family Dwelling Specialty
Code (Dwelling Code) for new buildings of similar structure, purpose or
location.
(2) Any portion of the
building has been damaged to the extent the building's structural strength or
stability is materially less than it was before the earthquake and is less than
the minimum requirements of the OSSC or Dwelling Code
for new buildings of similar structure, purpose or location.
(3) Any portion, member or appurtenance of
the building is likely to fail, or become detached or dislodged, or collapse
and injure persons or damage property.
(4) Any portion, member, appurtenance of the
building or ornamentation on the exterior of the building is damaged to the
point that it lacks sufficient strength or stability to resist a wind pressure
of one-half of that specified for new buildings of similar structure, purpose
or location without exceeding the working stresses permitted in the
OSSC or Dwelling Code for such buildings.
(5) Any portion of the building has racked,
warped, buckled or settled so walls or other structural portions have
materially less resistance to winds or continued earth movement than is
required in the case of similar new construction.
(6) The building or structure, or any portion
of the building is determined by an inspector employed or authorized by the
division to be unsafe for the purpose for which it is being used.
(7) The exterior walls or other vertical
structural members list, lean or buckle to the extent a plumb line passing
through the center of gravity does not fall inside the middle one-third of the
base.
(8) The building or
structure, exclusive of the foundation, shows 33 percent or more damage to its
supporting member or members, or 50 percent damage to the non-supporting
members, outside walls or coverings.
(9) The building or structure has been so
damaged to become an attractive nuisance to children.
(10) Damage resulting in faulty electrical
wiring, gas connections or heating apparatus, or other cause, is a fire
hazard.
