Journal of Japan Association for Earthquake Engineering, 2011 本論文では地殻内地震において自治体観測点で消失した地震波形の加速度応答スペクトルを推定するために、従来の研究で用いられている最大加速度比に加え、地震動スペクトルの卓越周期と構造物の固有周期との関係を考慮した応答スペクトル推定手法を提案した。加速度応答スペクトルを推定したところ、最大加速度比、卓越周期と構造物の固有周期との関係をパラメータとした推定式を用いた場合、最大加速度比のみの式に比べて、推定値と観測値の相関が高く、スペクトル形状もおおむね評価することができた。

Response Spectrum for Green Light-Induced Acceleration of Heading in Wheat cv. Norin 61
Plant Production Science, 2009 The response spectrum for green light induced-acceleration of heading in wheat cv. Norin 61 was investigated using narrow-bandwidth (10 nm) green light within the range of 520–550 nm. Heading was observed from approximately 30 days after emergence. The earliest heading was observed at 540 nm, which suggests the presence of a green light photoreceptor ...

The Acceleration Response Spectrum for Simulated Strong Motions Considering the Earthquake Characteristics of the Korean Peninsula [PDF]
Journal of the Korean Earth Science Society, 2007 The response spectrum is one of the important basic materials for the aseismic design. Numerous strong ground motions based on the seismic source characteristics for the earthquakes occurring in the Korean Peninsula were simulated to obtain the response spectra by using the computer program, SMSIM, developed by Boore (2005).

Study on the influence of the seafloor soft soil layer on seismic ground motion [PDF]
Natural Hazards and Earth System Sciences, 2021 In the complex medium system of the sea area, the overlying seawater and the surface soft soil have a significant impact on the seafloor ground motion, which brings great seismic risk to the safety of offshore-engineering structures.

A Semi-Analytic Method to Estimate the Response Spectrum of the Synthetic Acceleration Records with Evolutionary Spectrum [PDF]
Scientia Iranica, 2021 In this paper, we introduce a semi-analytic procedure for deriving the response spectrum of the synthetic acceleration records generated using the Double Frequency Model (DFM). DFM is a filtered white noise method for fully non-stationarity synthetic acceleration records.

A Centrifuge Model Test of the Ground Motion Response in a Moderately Stiff Soil
Shock and Vibration, 2021 The ground motion response in a moderately stiff soil in seismic events has been traditionally studied based on the actual field records which, however, have yet to offer consistent results regarding the amplification effect of the ground motion.
