A simplified method for preliminary seismic vulnerability assessment of existing building in Kundasang, Sabah, Malaysia

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) can be effectively used to evaluate the vulnerability of large number of buildings for study area with less computational effort. The data collection form of the Federal Emergency Management Agency (FEMA 154) for RVS was gathered for this purpose. The objective of this study is to assess the vulnerable building that tendency to be further detailed analysis by the calculation of score in RVS method. Pre-assessment towards seismic vulnerability of every individual building in particular area has been assessed and the information of buildings in study region consist residential, industrial, government, school building occupancies were recorded and spatially analyzed using Geographical Information System (GIS) framework. Buildings in Kundasang are considered as less further evaluation (34%) which need have detailed analysis by modeling the structure, while another 66% considered as safe building based on rapid visual final score
