A technique to evaluate the potential progressive collapse of reinforced concrete structure was conducted in this study. The analysis involved the removal of several columns on critical location of the building according to General Services Administration (GSA) 2013 provision. In each analysis, the demand-capacity ratios (DCRs) of structural elements were examined and compared to the defined acceptance criteria. To avoid structural building collapse progressively, DCR ratio of regular and irregular buildings should be less than 2 and 1.5, respectively. The result showed that the structure did not collapse with the removal single column only. Further to this finding, several columns need to be removed so that it collapsed progressively. In the case of regular structure, progressive collapse occurred after removing five columns on the side of the regular structure, with the maximum DCR of 4.66. In the case of irregular structure, progressive collapse occurred after removing four columns on the horizontal side in the middle of structure with the maximum DCR of 3.44.
