Rapid Visual Screening of Buildings for Potential Seismic Hazards : A Handbook

Federal Emergency Management Agency (U.S.)

en Limba Engleză Paperback – 3 aug 2017 – vârsta de la 18 ani

The Rapid Visual Screening (RVS) handbook can be used by trained personnel to identify, inventory, and screen buildings that are potentially seismically vulnerable. The RVS procedure compromises a method and several forms that help users to quickly identify, inventory, and score buildings according to the risk of collapse if hit by major earthquakes. This third edition includes extensive updates including:

Update of the Basic Scores and Score Modifiers
Update of the ground motion definitions
Preparation of additional reference guides
Inclusion of additional building types that are prevalent
Inclusion of additional considerations, such as nonstructural hazards, existing retrofits, building additions, and adjacency
Addition of an optional electronic scoring methodology
and more.
