A system for simulating the behavior of a reinforced concrete building being demolished by controlled explosion is developed. The purpose for developing the system is to examine the effects of blast location, blast size, blast sequence, delay time of blasts and other factors on a planning of blast demolition. It consists of a numerical analysis part to simulate the blast demolition of a space‐framed structure and a visualizing system to show the dynamic behavior obtained from the numerical analysis. The numerical analysis is based on the distinct element method, which is improved for consideration of the bending behavior of beams and columns. The elastoplastic behavior of the structural members up to the collapse are modeled in the analysis. The numerical data display system ‘AVS’ is employed, in addition to the computer code developed by the authors, to make the visualization system for three‐dimensional dynamic problems. In this report the method of numerical analysis, the visualizing system, and a comparison between the experiment and analysis are presented.
