摘要
FIELD: building, particularly working measures on existing buildings.;SUBSTANCE: method involves initially building up connection seams at ends of members to be reinforced within the limits of corner plates; building up intermediate seams in several sections; building up additional seams crossing above seams and arranged at paired flanges of main rod angle-bars. Dimensions of each additional seam are selected to provide flexure equal to flexure of each intermediate built-up seam. This provides sinusoidal rod flexure change with amplitude range of not more than ±0.5 m.;EFFECT: possibility to perform reinforcement operations at all stressed in centrally compressed rods, increased load-bearing capacity of the rods.;5 dwg
