SEISMIC AND IMPACT MITIGATION DEVICES AND SYSTEMS |
摘要 |
Systems mitigate structural damage by selectively engaging energy-absorbing structures only during impact events, including aircraft impacts. Systems include lateral dampening devices and/or seismic bearings between a structure and its foundation. Lateral dampening devices include a restorative member and/or reactive member configured to rigidly join the structure and the foundation and dampen reactive movement after the structure moves toward the foundation during an impact event. Seismic bearings include a top plate connected to the structure, a bottom plate connected to the foundation, and a resistive core between the top plate that dampens relative movement between the structure and the foundation. Seismic bearings may include a capture assembly that rigidly joins and dampens reactive movement between the structure and the foundation during an impact event. The structure may further include a ledge into which the top plate seats and dampens reactive movement between the structure and the foundation during an impact event. |
