Abstract
Author shown the numerical method of response analysis on the vibration of multi-storied building due to strong earthquake motion by using the electric digital computer, and discussed the accuracy of that calculation. In this paper he pointed out the problems about the actual calculations, the determination of structural behaviours for the response analysis. 1. In the case of the stories of building are not corresponding to the masses of multimass system, that is assumed as the vibrational model of building, there are very large error that is not safty side. 2. We have few data about the damping behaviour of building and elasto-plastic behaviour of structure, but these facts influenced to the results of the calculation more effectively. 3. He shown the examples of the effects on the response analysis due to the different kind of earthquake motion.
