Abstract

The blast analysis is limited to unit members because of its long analysis time. So this paper proposes the effective modeling and simulation technique for blast and collapse analysis of steel frame. In this study, analysis for static and blast load are performed with three kinds of elements such as solid element, plate element and thick plate element. Then, the most efficient element for blast and collapse analysis is determined by comparing the reliability of the results and calculation time. Also, quasi-static is applied to the analysis that has to be carried out by the static and dynamic analysis. The analytical models are the beam($H-294{\times}200{\times}8{\times}12$) and column($H-200{\times}200{\times}8{\times}12$). As the result, a thick plate element is most efficient for blast analysis. Through this way, blast and collapse analysis are simulated with the imaginary steel frame.
