A New Spectral Shape‐Based Record Selection Approach Using Np and Genetic Algorithms
Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 With the aim to improve code‐based real records selection criteria, an approach inspired in a parameter proxy of spectral shape, named Np, is analyzed. The procedure is based on several objectives aimed to minimize the record‐to‐record variability of the ground motions selected for seismic structural assessment.
