用丰富的高质量数字强震记录对台湾集集大地震及余震的长周期地震动特性进行了研究。
The study of long-period seismic wave is significant to the seismic design of the large-span engineering structures with long auto-oscillation period.
为研究长周期地震动反应谱特性，本文首次采用了地震学研究所使用的宽频带数字地震记录作为数据基础。
In this paper, we use the digital broad-band records to study the characteristics of long-period ground motion.
但是，在松软的土层上，长周期地震波的震动会被放大，可能使摩天大楼的摇摆更加剧烈。
But on soft soils, vibrations from long-period seismic waves are amplified, possibly exacerbating the swaying of skyscrapers.
