Static tests on a soil-steel bridge structure with a relieving slab

摘要

The paper deals with a new, arch road bridge made from structural corrugated plates, over the Plawna Stream, on a local road between Bystrzyca Klodzka and Ladek Zdroj in Stary Waliszow, Poland. The bridge replaced the old stone arch bridge that was destroyed during the flood of 1997. The steel bridge is founded on two continuous footings made of reinforced concrete. Its effective span is 10.00Â m and its clear height is 4.02Â m. The results of tests carried out on the bridge under three static load schemes after four years of service are presented. The average values of the measured displacements and strains in selected points and elements of the steel shell structure were found to be considerably lower than the ones calculated for the same load. Since designs of this type are more and more often adopted for small- and medium-size bridges, the conclusions drawn from the presented tests can be generalised to the whole class of such bridge structures.
