WebMay 1, 2024 · The unloading/reloading paths in the Pinching4 material were defined by 6 parameters, shown in Fig. 9 (b) and (c), where rDispP is the ratio of the displacement of the reloading point in the forward direction to the maximum deformation; rForceP is the ratio of the load of the reloading point in the forward direction to the maximum load; uForceP ... WebOct 1, 2024 · An analytical hysteresis material model for the seismic sway braces was developed and calibrated using the test data. The Pinching4 uniaxial material, along with a “zeroLength” element in OpenSees were used for simulation. The calibration of the analytical models resulted in a good consistence with the test results.
