Improved
seismic design and seismic retrofitting of vulnerable configurations will
increase the probability that homes are available to provide shelter
immediately following moderate to large seismic events. The purpose of this
prestandard is provide a methodology to identify and retrofit specific known
vulnerabilities in wood light-frame dwellings. Development of the assessment
and retrofit provisions has included use of the best available seismic numerical
modeling tools and engineering practices to assist in development of assessment
methods and to identify retrofit criteria to best achieve targeted performance
objectives. Use of the provisions is anticipated to improve earthquake
performance but is not intended to prevent earthquake damage.
This
prestandard provides a stand-alone resource for assessment and retrofit,
incorporating all provisions required for implementation, and includes figures
containing prescriptive, pre-engineered structural drawings and commentary, as
well as appendices that are expected to remain non-mandatory.
