衝突を考慮した時刻歴応答解析に基づく天井改修

－ 修正Hertzdampモデルの実用化 －

抄録

To make a specific ceiling earthquake resistant, we isolate the ceiling and wall surfaces to ensure the original acoustic performance of the design, place anti-vibration rubber bearings at the collision points between the ceiling and wall and analyzed the collision phenomenon between the anti-vibration rubber and the wall. We modified the Hertzdamp model, which can appropriately evaluate the current state of collisions, and used a method applied to a structural analysis model that takes dissipated energy into account, to rationally set the design seismic intensity of the ceiling surface and apply it to the renovation of an actual project.
