- Description
- A seismic risk analysis addressed to earthquake emergency management and protection strategies planning, requires territorial scale evaluation; to this aim a macroseismic method for the vulnerability assessment of built-up area is presented. The method is derived, in a conceptually rigorous way, by the use of Probability and of Fuzzy Set Theory, considering Macroseismic Scale definitions. Damage Probability Matrices are evaluated for the six vulnerability classes considered by the EMS98 scale; vulnerability
curves are drawn for these classes and for different building typologies. An analytical equation, interpolating the curves, is introduced as a function of an only one parameter the Vulnerability Index; it correlates the seismic input, in term of Macroseismic Intensity, with the physical damage, summarized by the mean value of the beta distribution. An average Vulnerability Index is associated to each building
typology, which may be refined on the basis of a seismic behavior modifier factor, and of a regional factor. A different uncertainty is associated with the vulnerability assessment and the consequent damage evaluation depending on the quantity and quality of data available for the analysis. By the use of statistical correlations, consequences scenarios (collapse, unfit for use buildings, deaths and injuries, homeless) and physical losses can be estimated.

- Description
- This report provides guidance on implementing the seismic performance assessment methodology set forth in FEMA P-58-1, Seismic Performance
Assessment of Buildings, Volume 1 – Methodology, to assess the seismic performance of individual buildings based on their unique site, structural,
nonstructural, and occupancy characteristics, expressed in terms of the probability of incurring casualties, repair and replacement costs, repair time, and unsafe placarding. This Implementation Guide contains examples illustrating the performance assessment process, including selected
calculation and data generation procedures, as well user manuals for selected electronic materials provided in Volume 3 – Supporting Electronic Materials and Background Documentation.

- Description
- This report describes a general methodology and recommended procedures to assess the probable seismic performance of individual buildings based on
their unique site, structural, nonstructural, and occupancy characteristics. Performance is measured in terms of the probability of incurring casualties,
repair and replacement costs, repair time, and unsafe placarding. The methodology and procedures are applicable to new or existing buildings, and
can be used to: (1) assess the probable performance of a building; (2) design new buildings to be capable of providing desired performance; or (3) design seismic upgrades for existing buildings to improve their performance.
