Abstract

Most people perceived that Malaysia was free from life-threatening seismic crisis. In
reality, seismic hazard in Malaysia is irrefutable, with seismic hazard originated from
seismically active neighbouring countries such as Indonesia and Philippines. There
were several methods that existed today used to predict buildings’ damage index by
using traditional non-destructive evaluation method, for examples, visual inspection
and instrument evaluation method. However, these types of methods are complex for
large structures since it was difficult to assess some parts of them. The evaluation of
damage index in Malaysia is limited especially when the building exposed to the
earthquake loading. Due to the increased number of earthquake incidents in Malaysia,
the development of damage detection method therefore become much more
challenging. This research presents the prediction of damage index of building using
IDARC 2D program which used Park and Ang damage model. Therefore, the
corresponding state of damage of the RC buildings can be identified in order to assess
the building’s condition under seismic loading. The time history analysis method was
applied using Aceh earthquake recorded at Ipoh, Malaysia which occurred in December
26, 2004 at Indian Ocean with magnitude 9.3 on Richter scale and the analyses were
carried out using ten intensities of seismic load; 0.05g, 0.10g, 0.15g, 0.20g, 0.3g, 0.4g,
0.5g, 0.6g, 0.8g and 1.0g respectively. The performance of the structure is shown by the
damage index recorded from IDARC 2D analysis and the corresponding state of
damage through previous study. The results show increased contribution to damage
index value with increased height of structures, increased maximum displacement of
structures and increased peak ground acceleration (PGA) value. The research resulted
in new method of prediction model of damage index of RC frame that can be determined
and according to the height, maximum displacement and PGA value to achieve
acceptable behaviour when possible earthquake event happened.
