Abstract
This study reports a brief study on linear dynamic analysis of Bakun Concrete Faced Rock fill Dam (CFRD). The analysis was conducted in order to determine the performance and behavior of the dam under seismic excitation. The dam was modeled as two-dimensional and developed based on the design drawing that is obtained from Sarawak Hydro Sdn. Bhd. The dynamic analysis of the dam is conducted using finite element analysis software package LUSAS 14.0 and the dam has been analyze as a plain stress problem with a linear consideration. A set of historic data, with Peak Ground Acceleration (PGA) of about 0.50 g is used as an earthquake excitation. The natural frequency and mode shape up to fifth mode of the dam has been obtained from the analysis to show the differences of the stress and deformation between each mode. The maximum horizontal and vertical stress of the Bakun dam was found and the distribution of them was discussed in form of contours. The deformation of the dam were also been discussed by comparing the maximum displacement for each mode shaped.
