Abstract
ACEVEDO, Ana Beatriz. SEISMOLOGICAL CRITERIA FOR THE SELECTION OF REAL ACCELEROGRAMS FROM THE COLOMBIAN NATIONAL NETWORK OF ACCELEROGRAMS FOR USE IN DYNAMIC ANALYSIS. Rev.EIA.Esc.Ing.Antioq [online]. 2012, n.17, pp.57-70. ISSN 1794-1237.
The use of real accelerograms as input in dynamic analysis is desirable as they provide realistic information about the nature of the strong ground motion; in addition, accelerograms capture different characteristics that can be produced by earthquakes at different locations. Colombian design code allows for the use of real accelerograms as input to time-history analysis. The horizontal component of a minimum of three different accelerograms is required by the code; all of the accelerograms must be representative of the expected ground motion at the site. In this paper the database of Colombian National Network of Accelerographs (Red Nacional de Acelerógrafos de Colombia, RNAC) is analyzed in order to assess the availability of records for different ground motion characteristics for their use as input in dynamic analysis. Groups of accelerograms that could be used as input for dynamic analysis were identified. However, if only records from the RNAC are used, it is not possible to completely cover the selection requirements specified on the Colombian design code.
