DYNAMIC PROPERTY OF THE 14-STORY STEEL-STRUCTURE BUILDING BY MICRO-TREMOR, MAN-POWER FREE-VIVRATION AND SEISMIC OBSERVATION

Abstract

There is a difference in the vibration characteristics between the real building and the analysis model used at the design stage. In this research, the micro-tremor measurement, the free vibration test by the human power and the seismic observation were carried out for the steel structure office building of 14 stories. These tests and observation results were examined from the small vibration level to the medium-earthquake response revel. And the validity of the dynamic analysis model used at the design stage was discussed.
