Data retrieving and recording equipment
Equipment 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 equipment
DIC 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 (4) RAMP
