This study investigates a progressive collapse of the eccentrically braced frame (EBF). For this purpose, ten different column removal scenarios are introduced to trigger the building collapse and it applies to four types of EBF such as K-shape, D-shape, V-shape and X-shape eccentric braces. The OpenSees is used to perform push-down analysis. In the analysis, the backbone curves for beam and brace of EBF are defined by FEMA-356 and the model proposed by Richard et al. (2006) is used with combination of FEMA-356 model parameter for the shear link. The collapse mechanism of four EBFs is identified by numerical analysis with the application of ten column removal scenarios. From numerical results, it is found to be that the absence of the alternative path and the yield of shear link can cause a sudden collapse of EBF, especially for V-shape and X-shape eccentric braces.
