|Description:||For the purpose of calibrating the pier model, a cyclic test is conducted with one of the 1/25th scale RC pier specimens. The lateral load is defined by 8 drift ratios, including 0.5%, 1%, 2%, 3%, 4%, 5%, 6% and 7%. Each drift level is repeated for 3 full cycles. A constant gravity load calculated from the FE model is applied vertically throughout the test. In the cyclic test, the top and bottom of the pier are fixed against rotation. The test result will be used to calibarte the FE model of the bridge pier.
* About the uploaded data for this experiment:
The Load and Boundary Conditions Box (LBCB) equipment at UIUC is very unique in that it combines six actuators to control one point in 6 DOFs, as if only one actuators is being used. What is of interest from the measurements is not the individual displacement of the six actuators (local coordinates), but the derived displacements in Cartesian (global) coordinates, therefore only the derived displacements (LBCB readings, LbcbReadings.txt) in Cartesian space are available.
Meanwhile, six external LVDT's are also installed to measure the specimen movement, so that the results can be compared with the LBCB readings. Therefore, the uploaded unprocessed displacement data (External_Sensors.txt) are from the six external LVDTs, these displacements are also converted to Cartesian space, which are uploaded as the derived data (ElasticDefReadings.txt).
