Structures can deflect under large earthquake excitation. Until now there was still lack of study to model non-seismic designed reinforced concrete structure under this conditions. This study investigated the load versus displacement and determined the building performance in terms of work and energy behaviour response under different seismic excitation data for different earthquake excitations. A ten storey building were modelled under four past earthquake records: Kunak, Bukit Tinggi, El Centro North–South and Pacoima Dam. When subjected to Pacoima Dam earthquake, the building exhibits largest pushing and pulling load which are 16,610 and 12,330 kN. Under Pacoima Dam earthquake also this building shows largest displacement compare to other three cases which are 518.4 mm for pushing displacement and 624.4 mm for pulling displacement. Apart from that, energy dissipated was also higher hence reduces the strength of the structure. This situation occurs due to the larger peak ground acceleration of Pacoima Dam earthquake which is 1.19 g. In addition, under Pacoima Dam earthquake, Kolej Delima UiTMPP would undergo partial collapse hence leads to severe damage to the structure. In overall, it was found that the building was sustained under low to medium excitations; however, it will collapse if under high excitations. This study was found important to predict the maximum behaviour of non-designed earthquake reinforced concrete structure. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
