Experiment-1: Demonstration of hybrid fragility modules of NISRAF using Burbank building
Experiment Type: Simulation
Description: A method for fragility curves generation based on hybrid simulation results along with the calibrated analytical response, is proposed and implemented in NISRAF. An analytical verification (fragility curves based on multiplatform simulation) is presented to validate the proposed method. The mean PGA from hybrid tests and the dispersion from references are used to generate fragility curves. A building model (built under ZEUS-NL platform) along with multiplatform simulation (coordinated by UI-SIMCOR, but all sub-structures are analytical (ZEUS-NL)) is conducted to verify the proposed experimental method for fragility curves. A six-story instrumented building in Burbank, California (latitude = 34.2A?, longitude = -118.3A?) is selected for this verification.

* 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, four external LVDT's and six strain gauges 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 and strain data (External_Sensors.txt) are from the four external LVDTs and the six strain gauges, the displacements are also converted to Cartesian space, which are uploaded as the derived data (ElasticDefReadings.txt).
