Hybrid simulation of 4 story frame to collapse using 1.5 story substructure

This experiment consists of a substructured hybrid simulation of a 4 story aluminum moment frame structure previously tested on the shaking table to collapse. The objective of the test was to verify the efficacy of new substructuring technique in being able to simulate structural response through collapse. The experimental substructure consisted of the lower one and one-half stories of the four story two bay frame.
