In this paper a new free on-line seismic database is presented. The database has 15 seismological and 26 deducted engineering parameters to search for available records for structural seismic analysis. As known, the selection and scaling of seismic records acquire primary importance in seismic analysis. Moreover, the application and development of Performance-based earthquake engineering (PBEE) implies finding records in different levels of the return period. This is a time-consuming and cumbersome procedure and the whole process is affected by great randomness. A database with specific parameters that permit finding best-suited records would prove very useful. As a consequence, both the randomness in the seismic action and in the results of the dynamic behavior of the structure can be strongly reduced. This is the objective of the new database.
In this work the authors describe the new database and develop a numerical application with 3 different bins of parameters of selection for records and results of structural analyses. The great usefulness of the database is shown.
