強震記錄之修正方法

Abstract

本研究共可分為四部份：第一部份為強震記錄的誤差校正，以消除在 高低頻中的誤差與由基線偏移所造成的誤差。第二部份為地震反應譜的製 作，使用頻域分析法求取單一自由度結構系統受地震力擾動之反應，以製 作每一筆地震記錄的反應譜。第三部份為設計反應譜的製作，最後則為對 設計地震加以探討。同時並針對台灣地區強震觀測網 SMA-1所收集的地震 加速度記錄由前述步驟作一系列的分析。 This research is devided into four parts to be discussed. The first part is the error correction of strong earthquake records .We can eliminate the error that existing in the high and low frequency and the error that producing by the movement of the base-line. The second part is the production of the response spectrum. We use the frequency domain analysis method to obtain the response of structure with single degree of freedom under the earthquake loads. Then we can product the response spectrum of every earthquake records.The third part is the production of the design response spectrum. Finally , we do the research of design earthquake. At the same time , according to the front statements , we can make a series analysis for those ground motion records that collected from SMA-1 strong earthquake observation net in taiwan.
