Numerical Simulation and Dimensional Analysis for Impact Resistant of the Building Structures

Theoretical analysis and numerical calculation of the building structures with impact resistant character depend on the parameters and  results of the  experiment. The dimensions of  the plototype is shrunken to  the experimental model. The  minification of the dimension and strength is not accordant between the plototype and the experimental model. Usually,the relative strength of the experimental model is greater than the plototype. Thus, the research on convergent-divergent ratio is needed when designing the experimental model with impact resistant character. The relationship between convergent-divergent of physical dimension and deformation, stress, pressure, wave speed, time, mass point speed is reasearched based on impact dimensional analysis. The lamination crack of concrete is also obtained.
