14 th European Conference on Earthquake Engineering SelEQ: a web-based application for the selection of earthquake ground motions for structural analysis João Dias, José Miguel Castro, Xavier Romão ; Marília Gonçalves; João Correia Lopes
What is SelEQ? SeleEQ is a web-based application for the search and selection of earthquake waveforms and records . SeleEQ incorporates filtering procedures allowing for the search of seismic records based on geophysical data but also on criteria such as spectral shape matching , following current seismic design code requirements.
SelEQ usage: search for waveforms Dropdown menus to define filters
Conclusions SelEQ is easy to use and allows for the flexible search for earthquake ground motions SeleEQ can be easily enhanced with the introduction of new filtering criteria. Contact us with suggestions: email@example.com In the context of performance-based earthquake engineering methods which increasingly rely on nonlinear dynamic analyses, SeleEQ is a valuable tool SelEQ does not require the installation of additional software
Future developments of SelEQ New filtering criteria are currently being introduced (e.g. search for records based on the Mean Period) Different response spectra and different damping values will be available (e.g. ASCE 07, user-defined spectrum, compatibility with displacement spectrum) Searching for Sets of Records according to current seismic deign code provisions (already under development) A linear optimization algorithm is being developed based on the MINOS large-scale optimization solver Heuristic strategies will be used to reduce the number of combinations to test (sets of 7 records using a sample of 50 records ≈ 100 million combinations)
