Development of Floor Vibration Analysis System using aFinite Element Analysis called "Yurayzer3"

In this paper we describe a new system floor vibration analysis using a finite element method which makes it easy for users to input data and visualize results. This system is linear elastic vibration analysis software called "Yurayzer3". It comprises a pre-processor unit, a calculation unit and a post-processor unit. The chief innovation of this system is the in-house development of a pre- processor and post-processor that simplifies the numerical inputs of information about nodes and elements. In order to verify the analytical accuracy of this system, the eigenvalue analysis is carried out and compared with measured values. This comparison showed a coefficient of variation about 10%, which is a level of agreement sufficient for the structural design phase.
