Abstract

In order that the ultimate state methods can be applied in dimensioning of the load-bearing elements in a conveyance it is required that their design loads should be determined during their normal duty cycle and under the emergency braking conditions.

This study aims to verify the predicted loading conditions obtained by theoretical analyses through experiments on a real object. Prior to the actual experimental procedure, limited to measurements of stress acting in the loadbearing cables in the conveyance, the system parameters have been identified. Special attention was given to parameters of roller guides and random irregularities of the guiding strings, which give rise to horizontal displacements of the conveyance and generate the conveyance- shaft steelwork interaction forces.
