INVESTIGATION OF BRIDGE DECKS WITH CONCRETE-ENCASED GIRDERS. STATICALLY DETERMINATE DECK TESTS UNDER DYNAMIC AND STATIC LOADS.

A twin-span bridge deck comprising concrete-encased steel sections and forming two continuous spans each of 19 m length was constructed on test floor No. 2 of the Structure Testing Centre of the CEBTP at Saint Remy les Chevreuse. This structure had been designed according to the calculation rules in force on the SNCF in 1973. The tests to which it had already been submitted (fatigue testing under service load to two million cycles, then statically tested) and its description are dealt with in Reports No. 5 and No. 7. However, brief mention should be made here of the fact that it concerns a bridge deck comprising 4 HEA 800 sections in AE 24 steel encased in concrete and corresponding to 2/3 of the cross-section of a real deck. This continuous deck of 2 x 29 m, after having undergone initial tests, was severed at its middle, and the present report describes the tests carried out on the two spans rendered "statically determinate" in this way.
