Abstract

A new material model that can show similar structural behavior under the blast load to the precise model with reinforcement and concrete was proposed to enable the progressive collapse simulation of a tall building. Von Mises yield model was applied to represent the ductile behavior of reinforced concrete and the yield strength, failure strength and elastic modulus were determined through repetitive comparisons of the analysis results from the precise model with fine mesh and the simple model with coarse mesh. The damage distribution of the simple model with the proposed material model was quite similar to the precise model though the number of elements of the simple model was a small fraction of the precise model. The proposed modeling method can be applied effectively to the blast analysis of tall buildings.
