scope:

(1) Basis of procedures. The seismic review procedures for structural systems were developed by modifying the screening procedures in FEMA 154.

(2) Application. The procedures in this document are intended only for the purposes indicated above, and are not intended to supersede or replace the provisions of TI 809-05 for the evaluation and rehabilitation of military buildings.

(3) Limitations. Review of site-specific seismic geologic hazards and nonstructural components and systems is beyond the scope of these procedures.

Purpose.

The purpose of this document is to provide procedures for the assessment of the relative seismic vulnerability of a large inventory of buildings at a military installation. The structural systems of each building or groups of structurally similar buildings in the inventory are reviewed to obtain a numerical score. The scores obtained for all buildings or groups in the inventory are recorded in numerical order in an Installation Report to provide a numerical ranking of the seismic vulnerability of the buildings. This ranked list will provide a basis by which military installations can determine the order for performing seismic evaluations. Other building-specific aspects to consider in conjunction with this review should include: general condition, known site-specific seismic geologic hazards, occupancy type, number of occupants, year built, plans for future use, and availability of alternative buildings (redundancy of function).

Applicability.

These instructions are applicable to all USACE elements and their contractors assessing buildings for seismic vulnerability at military installations.
