In this paper, The influence of the material constitutive parameters of concrete and steel and design parameters, such as the technique of the sudden column loss simulation, the effect of the column removal time in the structural failure pattern, the location of the removed column and the influence of the procedure chosen for progressive collapse verification (GSA vs. DoD) on the structural response of reinforced concrete frames in the progressive collapse analysis are investigated. In this study, an eight–storey regular structural building has been considered to investigate progressive collapse potential. Structural design is based on ACI 313–83 concrete building code for special RC frames and the nonlinear dynamic analysis is carried out using SAP2888 software. Eight independent failure scenarios are adopted in the investigation, including six external removal cases in different floors and two internal removal cases in the first floor. The results show that the design parameters and material properties have an important effect on the progressive collapse response of the structure. In addition, results show that catenary action effect plays a major role in the present progressive collapse analysis and the location of the removed element also has an effect on the propagation of collapse.<\div>
