| Summary: | Vulnerability assessment of reinforced concrete (RC) buildings is carried out by determining the load carrying and deformation capacities of the structural members. After yielding, the plastic deformation of RC flexural elements is concentrated in a restricted zone known the plastic hinge zone. In this study, the deformed shape and the ductility of remodelled RC heritage building subjected to local earthquake in Malaysia, which has low to moderate seismic excitations, were obtained. The geometrical, members topology, section property information, lumped weight at nodes, and iteration control of the prototype building’s structural damage simulation and deformed shape are done using finite element modelling subjected to the 2015 Ranau Earthquake records for 18 s of time history. As a consequence of the findings, the building is considered stable under low earthquake excitations. Even when there are minor fractures, the building can be occupied once it has been repaired. The prototype building, which is designed using previous design code of practice, has lower ductility and inadequate resistance towards moderate to strong earthquake excitations. The building would have significant structural damages if it imposed with high seismic intensity. Because the structure is constructed as a weak-column strong-beam, the plastic hinge propagations would be larger at the soft-storey columns. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
