Seismic damage and usability assessment aims to:

evaluate the (seismic) safety conditions of

constructions (buildings and others) affected by

earthquake damage,

in order to:

enable people to return home

social and economical activities to restart

USE

Management of post-emergency

(e.g: No. of shelters and temporary houses for

homeless people)Repair and reconstruction

(e.g.: strategy and overall funds needed, reimbursement

for repair of individual dwellings)Scientific advancements (in the long run)

(data collected contribute to the improvement of the

vulnerability assessment methods: e.g. fragility curves,damage probability distributions)


5/50

TOOLS

Inspection form and compilation manual

(approved by a decree of the Prime Minister in 2008)

Procedures set up by DPC(for collection of requests, team assignments, validation

of compiled forms)

Management Software (SET)

(based on procedures)

Compilation tools

(paper forms, pen & paper, PDA, )

USABILITY scale

A) USABLE Building can be used without measures.

Small damage, negligible risk for human life.

B) USABLE WITHCOUNTERMEASURES Building is damaged, but can be used whenshort term countermeasures are taken

C) PARTIALLY USABLE Only a part of the building can be safely used

D) TEMPORARILY

UNUSABLE

Building to be re-inspected. Unusable until the

new inspection.

E) UNUSABLE Building cannot be used due to high

structural, non structural or geotechnical risk

for human life. Not necessarily imminent riskof total collapse.

F) UNUSABLE FOR

EXTERNAL RISKBuilding could be used, but it cannot due the

high risk caused by external factors (heavy

damaged adjacent or facing buildings,possible rock falls, etc.)
