| Abstract |
The purpose of this study is to measure and analyse the geomagnetic flux density distribution in a steelconcrete campus building with a proper equipment referring to records. Also this study provides fundamental information and data about an appraisement standard and characteristics. The major conclusions that resulted from this study are following : 1) Analysises of geomagnetic flux density distribution of each measuring heights show that closer to the floor, the more unstable and farther from the floor, the more stable. 2) Analysises of geomagnetic flux density distribution of each floors show that each floor is not similar. Because the average geomagnetic flux density is different one another and correlation coefficient is below 0.5. 3) A symmetrical feature does not make symmetrical geomagnetic flux density distribution. 4) Geomagnetic flux density is from 20,397 nT to 105,744 nT in this invesigation, but the average of total geomagnetism is 44,137 nT and it is close to 50,000 nT which is Korean average geomagnetism. |
