The influence of the circular distribution of radial and tangential seismic velocity on the structural safety of residential buildings

The article presents the results of conditions circular distribution seismic vibrations generated during rock blasting. Scales Dynamic Influences [SWD] harmfulness vibration velocity on a two-storey building [SWDI] and five-storey building[SWDII] are given. value safe for construction buildings has been determined. They in Zone II Influence Scale SWD I II. magnitude components at same distance from source depends directional angle between line blast holes connecting centre surface mined block place measurement. For velocity, theoretical analysis change radial Vx tangential Vy depending was conducted. Graphs distribution, measured mining rocks complying with predictions were presented. residential buildings, SWDI SWDII, limit structures is
