Abstract
The block work house with Industrialised Building System (IBS) is innovated to minimize the rate of casualties from earthquake disaster. In order to improve the ductility of IBS block work house, rubber dampers were used to resist dynamic motion of a structure under seismic event. Through the research, the seismic performance of the 1:5 down scaled IBS block work column was obtained. The objective of this research is to create a robust IBS column by improving the damping system. Time History Test on shake table was conducted for IBS column models to determine its structural behaviour under seismic loading. Three types of IBS column models with different rubber damper type and application were tested. The rubber damping properties for two different rubber types were also obtained. Sabah earthquake 2015 with the PGA of 0.126g was simulated for the time history shake table test. The dynamic parameters such as acceleration, response spectra, and displacement were evaluated. As the results of the study, it was found that the hard rubber has better damping properties than soft rubber. The rubber dampers that installed in xy-plane horizontally on the column system is effective as vibration isolator.
