摘要: 
本文主要在探討地盤特性對阻尼修正係數的影響,首先以常態分佈圖模擬出不同地盤傅立業反應譜,再利用常態分佈圖製造不同地盤人造地表運動,將此不同人造歷時反應轉反應譜後求其阻尼修正係數,並觀察阻尼修正係數在不同地盤地表振動下之變化。另外再取真實地震記錄作分析,本文將地震記錄分為第一類地盤有近斷層效應與無近斷層效應、第二類地盤有近斷層效應與無近斷層效應及台北盆地。首先先檢查工址地震記錄是否有滿足規範的要求,若沒有則需先將工址地震記錄修正與規範反應譜相符之人造地震記錄,再將符合規範要求的人造地震記錄轉反應譜,以迴歸分析的方式求短週期結構與長週期結構之阻尼修正係數,另外再取結構振動週期為0.3秒與1秒當作短週期結構與長週期結構之阻尼修正係數當作對照,其結果顯示阻尼修正係數會受到不同地盤振動週期與地震頻率內涵影響。

This paper investigates the influence between damping coefficients and the characters of soil reaction. This study first simulates different soil interaction on the Fourier spectrum. These spectrums are categorized using normal distribution method. Such results are then used to modify the damping coefficients. Near fault and non-near fault measurement are verified by the analysis and observations from the earthquake records. Before the field measurements are analyzed, the earthquake records are exam by the building codes. The purpose for doing this is to compare the response spectrums between real earthquake and simulation data. Statically regression for short and long vibration period is also used to check the damping coefficients of the structures. Vibrational period of 0.3 or 1 second is utilized respectively as the parameters of the modification of the damping coefficient. The results show that modified damping coefficient would change due to soil reaction and the frequency function of the earthquake.
