Control Parametric Analysis on Improving Park Restoring Force Model and Damage Evaluation of High-Strength Structure

Figure 1

Influence on main structural responses of the numerical model by varying values of energy degradation parameter , stiffness degradation parameter , and fracture slip closure parameter . Note: for the convenience of comparative expression of various parameters in the same range, normalization processing was provided here, so that the stiffness degradation parameter and the energy degradation parameter .
