长期以来，结构设计专业一直对结构设计感兴趣，以抵抗潜在破坏性地震期间强烈的地面水平震动。这种地面运动的记录成功地为建筑规范、设计程序和强地面运动研究提供了数据基础。本《历史笔记》的目的是记录强地震动加速度计在美国（20世纪30年代）、日本（50年代）和新西兰（60年代）的早期发展——在相纸、蜡纸和胶片上记录的加速度计——并描述将这些模拟记录早期处理成适合数字计算机新兴力量的数字形式。地面加速度和结构加速度现在是地震设计和地震工程研究中熟悉的概念，尽管许多用户可能不熟悉早期识别它们、记录它们并将其作为有用数据呈现的工作。版权所有©2009 John Wiley & Sons， Ltd
The structural design profession has long been interested in the design of structures to resist the strong horizontal shaking of the ground during potentially damaging earthquakes. Recordings of this ground motion have successfully provided the data on which building codes, design procedures and strong ground motion research are based. The object of this Historical Note is to chronicle the early development of strong ground motion accelerographs in the United States (the 1930s), Japan (the 1950s) and New Zealand (the 1960s)—accelerographs that recorded on photographic paper, waxed paper and film—and to describe the early processing of these analog records into digital form suitable for the emerging power of the digital computer. Ground accelerations and structural accelerations are now familiar concepts in seismic design and seismic engineering research, though many users may be unfamiliar with early efforts to identify them, record them and present them as useful data.
