Abstract

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. An effective data processing procedure for the complex strain relaxation data is proposed. The 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
