System Identification on DBF - Rigid Links ON/OFF - Ground Links ON - Loading Beams ON - Actuator @ Floor 2

In this set of experiments, the DBF (damper-brace frame) system is identified dynamically with BWLN (band-limited white noise) and statically in five phases. Those phases are: Phase 1: BLWN Testing without rigid links Phase 2: BLWN Testing with rigid links Phase 3: Static Testing with rigid links (not conducted for Experiment 12) Phase 4: BLWN Testing with rigid links Phase 5: BLWN Testing without rigid links In these tests, actuator #4 is kept at 2nd floor (the second floor above the ground floor). The data is used to generate stiffness matrix of the structure which will be the basis for development of damper control algorithms of RTHS.
