Research On Explosion Shock Wave Effects On Column Layout And Inside Pressure Variations Of Steel Structure

Shock Wave caused by the explosion is a major damage in economic lossesand casualties. With the growing popular of light steel structure plant using inindustrial building area of our country. The research on the deformation analysisof steel structural after the explosion, mainly by post-disaster assessment andexperience, very few preventive measures was applied before construction.Therefore, the purpose of this research have a high research and available valueon the structure of the plant by the blast of whether there is value in use andwhether there are hidden dangers of secondary disasters,In the research of explosion shock wave effects on steel structure plant, thebest and most close to the actual research methods are make an actual explosionexperiments on light steel buildings. However, due to the actual experimentscannot be reused and restricted by the environment, test methods and fundingetc. researchers are difficult to got a applied to all similar to the universal law.Therefore, the use of computer simulation techniques providing an effectivetechnical support and research methods on the research explosion shock waveaffects light steel structure. The use of computer simulation techniques not onlycan make researchers to analyze deformation and dates that some realexperiments cannot be observed and take into account some of the problemswhich happen on the moment that shock wave contact with steel structure whenexplosion occurred. These advantages can play a significant role in the researchprogress and forming theory.This paper using nonlinear finite element dynamic software ANSYS/LSDYNA to simulation the situation that explosion happens inside of light steelstructure of McCain Harbin, trying to analysis and calculate the regional spread of the pressure variations when shock wave crossing the column and energytransfer processes of explosion shock waves effects on light steel structure. Andthe connection between the column of light steel structure and the pressure ofexplosion shock wave. The purpose of this paper is trying to provide referenceand technical support for further investigation.
