A Partial-Distributed Damage Method for Progressive Collapse of 3D Steel Composite BuildingsThe present paper studies the response of a 3D steel composite building to progressive collapse through the Partial Distributed Damage Method (PDDM). The method can assess the robustness of 3D steel and concrete composite structures, considering the introduction of partial damage to more than one element in contrast to the dominant Alternate Load Path Method (APM) which involves a complete loss of a member. Computational analysis using finite element software ABAQUS is performed, in order to account for the instability phenomena and assess the integrity of the structure. Considering a damage degree index dj, PDDM predicts lower and more critical collapse loads in comparison with APM.
