Abstract
The influence of vibration on surrounding structures is one of the most important factors considered during blasting demolition of high-rise buildings in metropolitan regions. In the controlled blasting demolition of a 22-story RC building in Kunming, several accelerograms on ground surface were observed. Based on analyses of vertical peak ground velocity which is normally used in blasting vibration evaluation, and horizontal spectral acceleration which is frequently used in earthquake engineering, the ground motion caused by building collapse was evaluated. The results indicated that the adoptive vibration decreasing measures had a good effect, and the slight damages of two nearby buildings could not be due to abnormal strong ground motion caused by collapse.
