Evaluation of Progressive Collapse Analysis using Beam and Shell Elements

The paper presents a progressive collapse analysis of a selected two-bay steel frame structure using the general purpose finite element package ABAQUS. The collapse behaviour of the steel frame structure subject to sudden column removal using different modelling approaches and different time variations is investigated. The structure is modelled using beam elements and combination of beam and shell elements. The modelling technique is identified to get a better understanding of the influence of using different types of elements when assessing the dynamic and collapse behaviour of structures.
