3. Numerical Simulation and Parametric Analysis 3.1. Finite Element Model and Parameter Selection 3.1.1. Finite Element Model The solid units of each component of the composite damper were created and assembled as a whole in the ABAQUS. Each component was simulated using C3D8R units. Material parameters and properties.

3.2. Analysis of the Time History Curves for Impact and Support Response Forces Figure 11 illustrates the time−history curves of the impact force and the support response force for test beams A1–B3. Time history curves for impact forces and support response forces are shown in black and red, respectively. It is generally possible to divide the impact−force–time history curve into segments for the primary wave peak, oscillation peak, secondary wave peak, and attenuation peak.

5. Parametric Analysis of Main and Sub−Frame Collisions 5.1. Influence of Collision on Structural Response The collision between the main and sub−frame was achieved by increasing the seismic wave acceleration to analyze the dynamic response under the collision of the main and sub−frame. Three different seismic waves, the El Centro wave, Taft wave, and artificial wave, were input in the X direction of the structure, and the peak acceleration was adjusted to 0.4 g.
