Hybrid testing, as an advanced seismic response simulation method, combines
experimental physical models with analytical numerical models; its versatility and
capability of testing large-scale specimens make it particularly applicable to the study
of seismic performance. Hybrid testing has been applied in approximately twenty
George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES)
research projects. This paper provides a review of hybrid testing techniques used in
these projects based on the information available at the NEEShub project warehouse.
An overview of hybrid testing is firstly presented. Then a list of NEESR projects
involving hybrid testing methods are discussed in details, including experimental
specimen, substructuring, integration algorithms, rate of loading and testing results
validation. The paper concludes that hybrid testing is an effective experimental
method in earthquake engineering simulation but needs further development in the
areas of providing more realistic structural responses and validated general hybrid
testing procedure for broader application.
