Full-scale tests of temporary steel (foot)bridges

Full-scale tests of temporary steel (foot)bridges

Paper in proceedings (conference paper)

The paper is focused on the problems of tests of steel structures intended for the temporary bridges and footbridges. On authors’ workplace, full-scale tests of existing railway temporary steel bridge and recently developed temporary steel footbridges have been performed. For the experimental verification of the railway temporary steel bridge in the real size the effective testing method non-requiring the fixed testing equipment anchored to the ground has been applied. In the case of newly developed temporary steel footbridges, the traditional loading methodology using the ballast load has been applied. The span of tested railway temporary bridge was 18 m and the spans of tested prototypes of newly developed temporary footbridges were 18 m and 36 m. The results of experimental verifications are the important information about the behaviour of real structures giving data of actual stresses, stiffness, deformations including the influence of individual structural parts and components on these, and can provide the backgrounds for the verification and correction of the calculating and evaluating procedures based on the usual analytical methods and numerical models.
