MDOF를 활용한 구조물의 층별 지진파 PGA 전달함수 제시

Abstract

About 3,000 MEMS sensors are installed within the Korea for the use of auxiliary seismic observation stations. Since the responses of the sensors installed in the building are different from the ground motions, this study proposes PGA transfer functions of a seismic wave for structures using MDOF analysis. The transfer function is represented as the ratio of the PGA of the seismic wave and PHA (Peak Horizontal Acceleration) on each story of the building. The resulting transfer function reveals that for the building with short natural periods, the TF is amplified, and for the building with long natural periods, the TF is attenuated.
