建築構造体における環境振動の伝搬性状に関する研究 : 4層3スパンRC構造物模型における振動伝搬性状

Abstract

This paper describes vibration propagation characteristics in the RC building construction by using 4 stories 3 spans prototype model of acrylic resin. We obtain some results of the attenuation of vibration acceleration level from the driving point and distribution of vibration acceletion level in the rooms next door to each other on the upper stories and the same story. We suppose it is important to consider the vibration mode shape of natural frequencies to obtain the attenuation in distance and distribution of vibration acceleration level near by natural frequencies. On the other hand, it is propriety to obtain the attenuation in distance of vibration acceletion level from a viewpoint of enegy flow far from natural frequencies.
