Measurement and analysis of vibration interrelated collapse process in directional blasting demolition of a high-rise frame-shear structure building

The Wuhan Overseas Tourism building is located between Yanhe Avenue and Huangpi Street. There was a 52 meter stretch available in the northward direction for a collapse. 31 meters to the east was a new public building whose wall was a glass curtain. 27 meters westward there was a two-storey garage. 15 meters away in southward direction there were community residences, constructed from which were brick and concrete or brick and wood. Thus, it was necessary to carefully control the influence of collapse vibration. The explosion district and the locations of measuring points are shown in Figure 1.
