Normal monitoring experiment400 mm380 mm, 360 mm, 280 mm, and 200 mm

Data retrieving and recording equipmentEquipment for dynamic DIC techniques
(1) Dynamic digital device-industrial CCD 
(2) Dynamic digital device-handy video SONY and Cannon EOS digital camera 
Traditional acceleration detecting device
ACC Accelerometer

Location for installing the data retrieving and recording equipmentDIC method
The experimental setup is shown in Figure 5. All dynamic responses of test structure are recorded by local images of structural response  
Data retrieving form accelerometer
Accelerometers are installed in each floor and base at horizontal direction

Input of earthquake data and external force for the steel structure Natural earthquake record
(1) Strong earthquake Kobe and El Centro 1940 earthquake record 
(2) Strong earthquake TCU, Chi-Chi earthquake record, 1999 
(3) White noise
