A simplified method for preliminary seismic vulnerability assessment of existing building in particular area of Kundasang, Sabah Malaysia region is proposed. The surveys are mainly focused on building inventory such as identifying the building occupancy, building type and the storey number of buildings for study area. Rapid Visual Screening (RVS) c...

Bukit Tinggi may experience low earthquake hazard but are still at high risk of substantial damage and loss. Dense concentration of buildings and infrastructure in some areas mainly due to the hospitality industry can generate this high risk level. This study is focused on identify, inventory and rank buildings in Bukit Tinggi to assess seismic vul...

... Detailed seismic vulnerability evaluation is a technically complex procedure and can only be performed on a limited number of buildings. Thus, it is very important to use simplified procedure that can help to rapidly evaluate the vulnerability profile of different types of buildings, so that the more complex evaluation procedures can be limited to the most critical buildings [12] To assess the buildings within the surveyed area, the RVS method as suggested by Federal Emergency Management Agency is used [13].Figure 4 Moderate seismicity FEMA 154 form (a) Basic Score Modifier for rapid visual screening (b). [14] Basic Structural hazard scores for various building types are provided in the RVS form.Figure 4(b) demonstrates the screener modifies the basic structural hazard score by identifying and circling score modifiers which are then added (or subtracted) to the basic structural hazard score to arrive at a final structural score, S. The basic structural hazard score, score modifiers and the final structural score S, are all related to the probability of building collapse [15]. The result of the screening procedure is a final score that may range above the basic score, with a high score indicating good expected seismic performance and a low score indicating a potentially hazardous structure. ...
... Ramly et al. [15] conducted a RVS of 1166 number of buildings in Pahang, Malaysia. Out of which 308 number of buildings required detailed investigation. ...
... The eight-story building in Chan Aye Thar Zan township and five-story building in Patheingyi township were found to have a high probability of Grade 4 damage at level 1 screening, but they may possess Grade 5 damage based on level 2 screening. Ramly et al. (2014) conducted a seismic vulnerability assessment of existing buildings in Bukit Tinggi, Pahang, Malaysia. They used the FEMA P-154 level 1 rapid visual screening method in moderate seismicity, and found that 26% of buildings needed further evaluation. ...
... The focus of earthquake-related studies is on seismic hazard assessment, with only a handful of studies conducted on seismic vulnerability and earthquake risk assessment. Amongst them are the evaluation of earthquake threat in Sabah considering the rate of earthquake events, the distribution of various magnitude quakes and the level of ground shaking [15]; the preliminary seismic vulnerability assessment of existing buildings using the simplified method that focus only in particular areas of Kundasang, Sabah [16]; evaluation of earthquake vulnerability in the context of physical (buildings only) components on Ranau, Sabah [17]; and the Earthquake Vulnerability Assessment (EVA) [14] to assess the earthquake vulnerability in terms of environmental and social characteristics. However, this study is only focused on the district of Ranau, which is one of the most prone areas to earthquake hazard in Malaysia. ...
