Hybrid Simulation of the Gravity Load Collapse of Reinforced Concrete Frames
A hybrid simulation test setup is developed to investigate and validate the application of hybrid simulation to the gravity load collapse of reinforced concrete frames. The OpenFresco software framework for hybrid simulation is used in combination with an event-driven real-time predictor/corrector ensuring continuous hybrid testing. A shear-critical reinforced concrete column loaded through three dynamic actuators constitutes the physical substructure while a nonlinear ductile reinforced concrete frame makes up the numerical substructure within the OpenSees environment. This paper presents a nonlinear transformation method designed to allow for an accurate application of the loading on the specimen and a new predictor corrector scheme to eliminate force feedback oscillations. Validation of this hybrid simulation setup is achieved through a comparison with a shaking table test of the same reinforced concrete frame by performing two hybrid tests. Based on the results from the hybrid tests, procedures which are expected to improve the results of the hybrid test are presented.
