| 中文摘要 | 本文利用羅東大比例尺模型試驗(LSST)的強震記錄,印證基礎埋置式樓房系統 在強震時的土壤結構互制歷時反應,結果發現彈性半空間理論低估了阻尼效應,促使結構體 的預測反應值高估了。此現象,尤以能譜圖方面的比較最為顯著。參考黏彈性半空間的理論 後,本文以近似彈性半空間的理論作為分析模式,由預測結果與記錄值之比較,顯示本文模 式確實能模擬結構體的歷時反應,藉此供作研究分析之參考。 |
| 英文摘要 | By using the seismic records of LSST, the prediction of the seismic behaviour of building-embedded foundation systems in time domain was identified. The results of the elastic halfspace foundation show that the damping is underestimated and the seismic response of the structure is overestimated. This effect is significant especially in the power spectrum. Based on the elastic halfspace and viscoelastic foundation, a simple approximate model in presented. The comparison of the predictions with the records shows this approximate model indeed can simulate the seismic behavior of the building-embedded foundation system in time domain. |
