In the present paper, the application of the centre hole technique to concrete structures is
examined and an efficient scheme developed for the determination of the in-situ stresses.
effective data processing procedure for the complex strain relaxation data is proposed.
variability of concrete as a material makes it necessary to improve on previous techniques, also
the high degree of redundancy in the test data must be dealt with.
In the proposed procedure, a
so-called 'surface stress' is defined which allows for the elimination of the influence of any
surface effect which inevitably exists in concrete struct...
