本文从基本层面回顾了强震地震记录信息的呈现方式。参考 1971 年圣费尔南多地震中帕科伊马大坝获得的强震记录来说明各种表示方法。作为大多数抗震结构设计规范的基础的加速度响应谱，响应谱的历史发展可以追溯到最初的概念。概述了通过使用“伪”响应谱来简化表示，以及使用谱来定义地震烈度。强烈震动记录 1906 年旧金山地震后，工程师们充分意识到设计建筑物以抵抗地震力的必要性。人们认识到需要实际地震的强震记录作为设计信息。当时，地震学家正在进行远震记录，但这些记录没有表明震中地区运动的性质。
This article reviews, at an elementary level, the ways in which information from strong-motion earthquake records may be presented. The various methods of presentation are illustrated with reference to the strong-motion records obtained at Pacoima Dam, in the San Fernando earthquake of 1971. As acceleration response spectra from the basis of most codes for the design of earthquake resistant structures, the historical development of response spectra is traced from the initial concept. Simplification of presentation by the use of 'pseudo' response spectra, and the use of spectra to define earthquake intensity are outlined. STRONG-MOTION RECORDS It was after the 1906 San Francisco earthquake that engineers became fully aware of the necessity to design buildings to resist earthquake forces. It was recognised that strong-motion records of actual earth quakes were required as design information. At that time, seismologists were making teleseismic records, but these gave no indication of the nature of the motion in the epicentral area.
