Safety Assessment Method Based on Response Spectrum Analysis of Building Structures to Blasting Vibration

Abstract:

t is Founded that S_R can comprehensively reflect the general effect of the blasting vibration and the influences of Structural damage of vibration by structure dynamic characteristics. The computation and the analysis of 132 groups blasting vibration data indicates that probability of destroying of general houses by blasting vibration increases significantly when [S_R]5.5. And then the [S_R]5.5 is used as a supplementary of blasting vibration damage safety criterion standard of 2sd construction. On this basis, the unified security criterion of blasting vibration safety is initially founded through introducing the concept of P_rs of structures blasting vibration spectrum safety factor.
