摘要:
本文简要地总结了国外进行人造地震波的研究概况,并从工程角度出发,对满足平滑设计谱的人造地震波的合成方法进行了研究,并编制了计算机程序。这一方法是将地震运动表示为具有均匀分布随机相角的谐波振功的线性组合,然后,反复调整其富氏谱的幅值,强迫其反应谱逐步地收敛于平滑的设计谱,以获得与地震烈度和反应谱等价的人造地面加速度时程曲线,为重要工程的动态设计提供依据。
Abstract:
In this paper, a survey is made of the research works on artificially generated earthquake records. For stractural design purposes, the author proposes a method of creating artificial earthquake acceleration-time records which are compatible with a given smooth design spectrum, and developes acorresponding computer program. This presupposes that the ground motion in earthquake consists of a linear combination of various harmonic motions with stochastic phase angles. The amplitudes of the Fourier spectrum are then modified step by step until the amplitudes of response spectrum of the artificially generated earthquake record match the given design spectrum most closely. The resulting artificial time records are representative of the given earthquake intensity and design spectrum, and will provide a reliable basis for the aseismic design of important engineering structures.
