SHAKING TABLE STUDY AND MODELLING OF SMALL SCALE BUILDINGS UNDER SEISMIC LOADING FOR EDUCATIONAL PURPOSE ANALYSIS

Abstract

Earthquake has become a recurrent phenomenon around the globe, including Malaysia, which causes many casualties and damages to the building structures. Researchers have carried out significant experimental studies for the development of earthquake engineering to investigate the seismic effect of a building under seismic loading, which can be achieved through the utilization of special instrument such as shake table. Shake table is an instrument which can simulate earthquake ground motion and help in determining the dynamic properties of structures under this condition. A portable uni-directional electro mechanical driven shake table of size 24 X 14 and four (4) types of small-scale building models has been developed in this research, which were unbraced structure; braced structure; pendulum tuned mass damper structure; and spring isolator structure. The fabrication of shake table and small-scale buildings used materials including plywood, aluminum and plastic rules. To conclude the study, the performance of shake table was validated and comparison in the seismic behavior of each building models has been made via experimental tests. This research has promising application for hands-on laboratory experiment and better comprehension toward the seismic behavior of building structures during an earthquake for the undergraduate students of University Malaysia Sabah.
