本文的目的是了解建筑物和地下地面对脉冲式地震动的响应特征，阐明脉冲式地震动的独特响应产生机理。为了实现这一目标，我们利用模态分析和波传播理论分析了均匀弹性剪切梁在简单脉冲波（正弦脉冲和Ricker小波）作用下的响应。重点研究了最大响应的时间、位置和量，以及各自然模态对最大响应的贡献率。此外，我们定性地参考了损伤集中特征。
The objects of this paper is to comprehend the response characteristics of buildings and subsurface ground for pulse-like ground motions, and to clarify the generating mechanism of the distinctive responses. To achive the objects, we analyze the responses of uniform elastic shear beam for simple pulse waves (sinusoidal pulse and Ricker wavelet), with modal analysis and wave propagation theory. Especially, we focus on the time, the position and the amount of the maximum response, and on the contributing ratio of each natural mode for the maximum response. Additionally, we refer to damage concentration characteristics qualitatively.
