Description
Summary:The paper is presented the results of research conducted on the posttensioned prestressed concrete spans made with precast Π-beams of part of seventh spans Eugeniusz Kwiatkowski road viaduct located in Gdynia (between supports no. 97-104) under static field load test. Heavy trucks were used as static loads. Superstructure (main beams), deck slab, and fixed and moving bearings, and also supports (abutment and piers) in both roadways of trestle were tested. Specification and range of conducted research are presented with analysis of results from the tests and calculation, which allowed to the estimate span structures behavior and their actual load-capacity before allow them to normal service on B-class of loads.
