METHOD TO DETERMINE VALUE OF PRESTRESS IN REINFORCEMENT OF FINISHED BUILDING STRUCTURE Russian patent published in 1995 - IPC

Abstract RU 2029931 C1

FIELD: construction. SUBSTANCE: longitudinal oscillations of variable frequency are excited in any reinforcing rod being a part of the structure concurrently with structure loading. Resonant frequency of oscillations and logarithmic decay decrement are measured in each reinforcing rod. Prestress of reinforcing rods in entire building structure is determined as a result of comparison between measured parameters and their proper reference values. EFFECT: accurate method of determination. 2 dwg
