Static tests on road bridge made from steel corrugated plates with relieving slab

The paper deals with a new arch road bridge made from MultiPlate V45 corrugated plates, over the Plawna River on a local road between Bystrzyca Klodzka and Ladek Zdroj in Stary Waliszow (Lover Silesia Province), Poland. The bridge replaced the old stone arch bridge destroyed during the flood of 1997. The steel shell of bridge is founded on two continuous footings made of reinforced concrete. Its effective span is 10.00 m and clear height -4.02 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 loads. 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 generalized to the whole class of such bridge structures.
