4 Additional Notes

5 MR Damper Made by LORD Model: RD-1005-3 Serial: 0409010 Operation between 0-1 Amp current Pictures about how the damper is attached to the structure can be found under Experiment- 2.

6 Current Driver The current driver used in these tests do not have any brand/serial #. The current driver equation is A = V/1.70

7 Force Sensor and Actuator LVDT The MTS load cell and Schenck actuator LVDT is powered by MTS Flex GT Controller. An output has been sent from controller to DAQ system.

8 Laser Sensor Conditioner The laser sensors are powered with LK- G3001V Controller The signal has been filtered with a low-pass filter at 300 Hz.

9 dSpace To regulate the current level sent to MR Damper, dSpace has been used. For semi-active case voltage regulation, floor accelerations, first floor relative displacement and load cell coming from MTS controller are divided with tee-converter to Donghua and dDspace. For ADC[1-4], resolution is 16 bit. For ADC[5-8], resolution is 12 bit.
