ABSTRACT:
A plurality of strain gages are installed on a structural body at n positions thereon. A concentrated reference load is applied to the structural body at one of the n positions and strains developed in the structural body at the respective n positions are measured when the concentrated reference load is applied to the structural body. The measured deformations are divided by the concentrated load reference to produce strains per unit load. The above process is repeated at each of the n positions to generate the practical equations given below: ##EQU1## where .kappa.11.about..kappa.nn represent strains per unit load, A1.about.An represent estimated loads (unknowns), and .epsilon.1.about..epsilon.n represent measured strain data. Then n measured strain data are collected from the strain gages while the structural body is in operation and estimated loads are calculated from the collected n measured strain data according to the practical equations, whereby loads applied to the structural body at the respective n positions can be estimated in real-time.
