“…The original tectonic plate and fault lines show that Malaysia falls under the low-seismicity group [14]. Geographically, Malaysia is located near the Australian Plate, where it is actively placed south-westward underneath the Eurasian Plate in a stable Sunda platform [15].…”

This paper presents a case study regarding failures of structural buildings which occurred in Malaysia after the first significant earthquake event dated on June 5, 2015. Ranau is a locality situated in Sabah, Malaysia on the island of Borneo. The seismic activity was triggered when an earthquake with a magnitude of 5.9 afflicted Ranau, including seven other districts that also felt the tremors. Even though the impact of magnitude was undisputedly not high, the severity level of damages was found to be absolute (irreparable) in the structural RC beam-column joints and soft-storey buildings. Most of the buildings in Malaysia were built without the consideration of seismic design, and thus a major factor in structural failure. The earthquake has directed the seismic demand, while the total displacement was concentrated at the weakest floor that caused more damage to the building. This paper shows the causes of beam-column joint damages and explains the proposed (to-date) strengthening methods. Future studies related to seismic activities are in need to analyse the performance of the existing design of structural RC members and propose seismic design in Malaysia.

“…Fragility curves are log-normal functions that can predict the probability of structural and non-structural damage states for a given level of earthquake response [21]. Fragility curves can be defined as a conditional probability that provides a possibility that a structure will meet or exceed a specified damage level for a given ground motion [22]. Though fragility curves are specific to structural typologies, they can be adapted to any region for similar building typologies and ground conditions, and to derive vulnerability functions using consequence functions [23].…”

Mymensingh municipality is highly vulnerable to earthquake as it is located in close proximity of Madhupur Fault, Dauki Fault and Plate boundary Fault-2 as per a recent finding. As a result of rapid urbanization, economic expansion, population growth, urban-rural migration has made the locality more vulnerable to earthquake. This paper aims to assess the seismic vulnernability and potential economic loss at the event of earthquake for ward 14 of Mymensingh Municipality. For the assessment of seismic hazard, 12 borehole tests and 8 microtremor array measurements have been done. Based on the data of those tests, earthquake intensity map has been prepared using Geographic Information System (GIS) for the study area. For the estimation of economic loss caused by earthquake, potential building damage and human casualty have been estimated. For the assessment of potential building damage, a building inventory of the study area for 735 buildings has been done and potential building damage has been calculated by using fragility curves. Based on the occupancy rate of the study area, possible human injury and death rate have been estimated by using Morbidity Model proposed by Coburn. Combining the building vulnerability and human casualty, the potential economic loss at the event of earthquake for the study area has been estimated.

“…Owning to the accuracy of the IDA in capturing the structural behavior and response due to seismic excitations and to the increasing advancement in computers capabilities, the IDA is used extensively in deriving fragility and vulnerability curves for almost all of the engineering structures. For example, Saruddin and Nazri (2015) developed fragility curves for the representing building stock in Malaysia, i.e. RC and steel moment resisting frames.…”

The fragility curves are an essential tool in the seismic assessment of structures and provide a versatile tool to conduct vulnerability analysis for retrofitting and strengthening purposes. The available advancements of computer computational power led to the improvement of the efficiency of the analytical fragility curves. Therefore, this paper focuses on reviewing the recent research developments in the analytical fragility analysis methods. Furthermore, the developments of the intensity and damage measures are presented. In addition, the joint hazards effects on structural fragility are addressed particularly for the environmental degradation and mainshock-aftershock sequence. Finally, recommendations are presented for improving the fragility analysis and highlighting the possible future research areas.
