Seismic Indexing System for Army Installations. Volume II. Seismic Hazard Priority-Ranking Procedure for Army Buildings: Basic Concept

摘要

The Army is developing a capability to economically identify and evaluate the seismic capacity and strengthening strategies for essential and high potential loss facilities at Army installations, i.e., Mission Affordable Seismic Strengthening (MASS). One of the technological needs to achieve MASS is the development of a facility seismic hazard indexing procedure to identify existing facilities that are potentially seismically hazardous based on the information in the real property inventory for Army installations. The basic concept of a seismic hazard priority-ranking procedure for Army buildings described in this volume is an integral part of the facility seismic hazard indexing procedure. The basic concept provides the framework for a preliminary, subjective seismic safety evaluation of existing Army buildings based on an analysis of the information contained in the inventory of Army military real property and the anticipated seismic exposure hazard. Further development of the basic concept is required to refine the basic indices, to establish weighting factors, and to automate the concept.
