A three-tiered process is presented for seismic evaluation according to a range of building performance levels. The deficiency-based procedures allow evaluation and retrofit efforts to focus on potential deficiencies for a specified set of building types and heights. The systematic procedure sets forth a methodology to evaluate the entire structure in a rigorous manner.<\/p>\n<p>Analysis procedures and acceptance criteria are established, and requirements specified for:<\/p>\n<ul>\n<li>foundations and geologic site hazards;<\/li>\n<li>building components; and<\/li>\n<li>seismic isolation and energy dissipation systems.<\/li>\n<\/ul>\n<p>This standard is a primary reference for structural engineers addressing the seismic resilience of existing buildings, and for building code officials reviewing such work.
