Development of Vibration Experiment Education Materials for Structural and Soil Dynamics

Abstract eng:
A series of dynamic vibration experiment and educational devices, collectively named ‘BURURU’ are developed to facilitate and improve education regarding structural and soil dynamics for university students and professional engineers, and to encourage seismic retrofitting among members of the general public by clearly demonstrating the effectiveness of such retrofitting. The BURURU series consists of various kinds of vibration-producing devices and building and soil models. Web-based simulation tools and other experimental materials are also developed and made available for specific purposes and/or objectives. Vibration tables of various types, sizes, and driving mechanisms, including small shaking platforms have been developed to serve as platforms for forced vibration testing. The devices utilize various pendulums, frame structures of different sizes, viscous dampers and base-isolation mechanism, soft soil to demonstrate soil amplification, structure interaction and liquefaction and even indoor furniture models. In order to support online virtual experimentation, a web-based, real-time dynamic simulator using FLASH action script is also available. It is felt that by showing various dynamic tests immediately after teaching the formulation of dynamics, students more easily understand dynamic phenomena, residents can fully comprehend the importance of seismic retrofitting, and all parties concerned can be expected to more enthusiastically work on concrete disaster prevention activities.
