Abstract: Progressive failure can be described as step-by-step failure in building caused by the sudden loss of one or a few structural elements, which generates a chain reaction of failures for the adjacent structural elements, which leads to the entire structure failing. One of the factors that can amplify the damage caused by progressive failure is building irregularity. Three dimensional modeling, using the finite element method was developed to investigate the progressive failure of high rise irregular plan building consist of 30 storey with rigid moment resisting steel frames. Non-linear dynamic analysis is carried out following GSA guidelines using ABAQUS software. The modeling techniques were described in detail. The obtained numerical results are compared with experimental data and good agreement is attained. Using this model, the structural behavior of the building under the sudden columns loss for different scenarios of column removal were assessed in detail.
