FIELD: building, particularly working measures on existing buildings.
SUBSTANCE: method involves dividing structure in several parts by vertical cross-sections so that each part has simple three-dimensional shape; dividing each part separately into zones through part height so that each zone includes 3-5 stories; leveling zone boundaries for all structure parts at the first story level; installing three-component vibratory pickups along vertical axis of each structure part; measuring spatial oscillations at opposite boundaries of neighboring zones abutting zone to which dynamic load has been applied in vertical and horizontal directions at load application lever in points of three- component vibratory pickup installation in adjacent structure parts.
EFFECT: possibility to determine area characterized by deflected mode change.
