The U.S. Bureau of Mines studied the problems of blasting-vibration-induced structural response and cracking of low-rise residential structures in a series of research projects between 1976 and 1983. This paper summarizes the published Bureau findings and presents them from the point of view of the cracking and failure of the construction materials used for homes. The damage data suggest that, for plaster and wallboard attached to the super-structure, an increase in the rate of cracking is not likely to result from blasts generating vibrations of less than 0.5 In/s. Data on cracks in masonry walls suggest that blast-induced vibration levels of up to 3.0 In/s may be a threshold for local block-length cracks. However, additional data are needed to quantify vibration level effects necessary to generate stair-stepped cracks in masonry walls, which indicate loss of shear load capacity.
