An earthquake occurs at any place that is located along or nearby the Pacific Fire Ring. The differences of earthquake excitation depend on the magnitude and peak ground acceleration whether in low, medium or high region. Four different previous earthquake excitation records were adopted in this study namely Kunak, Bukit Tinggi, El-Centro and Pacoima Dam earthquakes to analyze the work and energy response of prefabricated concrete structure that was designed using BS8110. It was found that the structure did not experience damages under low Kunak and Bukit Tinggi earthquake excitations but minor damages under El-Centro and major damages under Pacoima Dam earthquake excitations. Major damage occurred at the connection of the structural element such as beam-column connection and slab-beam connection due to large energy dissipation, reducing the structural strength and stiffness. This study is important in developing the best retrofitting methods for the structures after-impact maintenance. ©2021 by authors, all rights reserved.
