APPLICATION OF PLANAR MODELLING OF BAR STRUCTURES DURING THE EXAMINATION OF THE SZÉCHENYI CHAIN BRIDGE

Abstract

Planar modelling of Széchenyi Chain bridge used in association with the load test after the renewal in 1987-88 is presented. The computation was devoted to demonstration of the distribution of the tension forces in the suspension bars. In order to get adequated results, a second order theory was used. It was necessary to take the 'load history' of the bridge into consideration. This effect was evaluated by a 'try-and-error' method.
