建築構造体の振動性状に関する実験的モーダル解析

Abstract

This paper describes some results of vibration propagation characteristics of two rooms next door to each other in the actual building construction (including floor, walls, and upstairfloor) by experimental modal analysis. In addition, we investigate about vibration response of measuring points by forced response and sensitivity analysis. The results are summarized as follows. The vibration of lower modes gives larger effect to vibration propagation characteristics of building construction than that of higher modes. It is considered that the vibration transmission of higher frequency may be caused by energy flow.
