8.22.010 Purpose. The purpose of this chapter is to promote
public safety and welfare by reducing the risk of death or injury that may
result from the effects of earthquakes on unreinforced masonry bearing
wall buildings constructed prior to 1954 (the adoption date of the
Building Code requiring earthquake resistant design of buildings) . Such
buildings have been widely recognized for sustaining life-hazardous
damage, including partial or complete collapse during moderate to strong
earthquakes.
The provisions of this chapter are intended as minimum standards for
structural seismic resistance established primarily to reduce the risk of
life loss or injury. Compliance with these standards will not necessarily
prevent loss of life or injury or prevent earthquake damage to
rehabilitated buildings. This chapter does not require alteration of
existing electrical , plumbing, mechanical or fire safety systems unless
they constitute a hazard to life or property.
This chapter provides systematic procedures and standards for
identification and classification of unreinforced masonry bearing wall
buildings based on their present use. Priorities, time periods and
standards are also established under which these buildings are required to
be structurally analyzed and anchored. Where the analysis finds
deficiencies, this chapter requires the building to be strengthened or
demolished.
