Abstract
Based on the characteristics of blasting vibration wave and the design response spectrum, this paper puts forward an analytical method on dynamic response of building structure in blasting vibration. Example analysis shows that this analysis method is more reliable and scientific compared with the analytical method which takes the single physical vibration parameter as the criterion to assess the damage in blasting vibration; the blasting vibration load is determined by the first vibration mode, and the influence of higer level vibration mode can be ignored. The interlaminar shearing force distribution carries the feature that the shearing force on the top of the building structure is smaller than that on the bottom. Therefore, in blasting vibration, the bottom of a building structure is easier to be damaged.
