The seismic analysis of a dam structure is a crucial consideration in its design and construction. Even though the dam in Malaysia is not located in an earthquake-prone location, various seismic activities in neighboring countries have been documented, which might have an impact on the dams in Malaysia. In the topic of structural seismic performance, there has been an enormous amount of study conducted. However, this research and work practice is not fully implemented in Malaysia. This research was conducted by applying incremental dynamic analysis (IDA) to assess the seismic performance of a dam structure using finite element software. The incremental dynamic analysis was performed at Sungai Kinta Dam which is a roller-compacted concrete gravity dam located at Kinta, Perak. The crack patterns, maximum displacement, maximum normal, and shear stress were determined in this study. The relationship between the intensity of earthquake motions and the damage patterns was investigated. The Sungai Kinta Dam’s cracking patterns steadily got worse as the peak ground acceleration got faster. It was also found that the displacement increases when the peak ground acceleration increases similar with the normal and shear stress. The normal stress was determined to be maximum at the crest of the dam while the shear stress was investigated to propagate from downstream to upstream of the dam. The structural performance of a structure was examined in detail using this method. This study’s findings can potentially be used to support design optimization or seismic evaluation of an existing dam structure.
