Seismic Capacity Using Finite Element Analysis: A Case Study of Murum Powerhouse
Journal Title: Acadlore Transactions on Geosciences - Year 2023, Vol 2, Issue 2
Abstract
Malaysia has become more aware of potential seismic hazards after one of the most devastating earthquakes in 2015. It is necessary to make seismic analysis of areas with active fault lines and access the current structure design in the seismically active areas. Therefore, this study aimed to investigate and analyse the structural response of the Murum Powerhouse under seismic load using the finite element modelling software ABAQUS. It was discussed to evaluate the seismic capacity of powerhouse structure under different seismic loads using the dynamic time-history analysis. The assembled model was subjected to seismic load, and the earthquake time history was taken from the Eregli station in the Kocaeli earthquake in Turkey with peak ground accelerations (PGAs) of 0.1g, 0.2g, 0.3g, 0.5g, and 0.8g. The scope of this study included the analysis of acceleration, displacement and principal stress response of the Murum Powerhouse structure. Further findings showed that the Murum Powerhouse was likely to have structural failure in earthquake, based on the model using the ABAQUS software with 0.3g PGA and above. The powerhouse model only passed the allowable displacement required by Uniform Building Code 1997 (UBC97) with PGAs of 0.1g and 0.2g. Further recommendations were made in this study in order to determine the response of the facility under different conditions.
