中文摘要 | 本文在建立臺灣地區設計反應譜及地震危害度分佈圖。由臺灣地區強震網之記錄 ,依其不同地點土質狀況分成二種:堅硬土壤及鬆軟土壤,進行分析。由統計之觀點對反應 譜值受不同地震規模及震源距離影響予以探討,進而判定以震源距離在 50 公里以內,地震 規模大於 6.0 以上,且不在此範圍, 但是地表加速度值大於 0.2g 以上時之強震資料做為 基本數據,去發展設計反應譜。利用危害度分析方法,建立在某一特定超越機率下之反應譜, 配合此均佈危害度反應譜,臺灣地區之地震危害度分佈圖則予以建立。 |
英文摘要 | The purpose of this paper is to develop design spectra as well as a risk map for the Taiwan area. Two types of site conditions are separated from the SMA-1 network recordings: hard sites and soil sites. From a statistical point of view, the effects of different magnitudes and hypocentral distances on response spectra are studied. The final site-dependent design spectra for hard sites and soil sites are calculated based on the data with M ≧ 6.0 and with a hypocentral distance of less than 50.0 km. including the data with peak ground acceleration greater than 0.2g which was not included in the data base. The hazard spectrum, which represents a response spectrum whose spectral amplitudes are associated with known probability of exceedance are also studied. With this idca of uniform risk response spectra, the iso-intensity map of spectral amplitude are developed. |
