Study of Double Plated Steel Bridge Decks

摘要

Four special composite tests panels were fabricated and tested. These test panels consisted of two thin parallel steel plates held together by a group of thin studs welded to the plates. The space between the plates was filled with an expanding cement - lightweight concrete. Two test panels were tested in flexure, and two in direct compression. The object of this pilot study was to see how such sandwich panels behaved under load. Results showed that the ultimate capacity of the panels was 50 percent greater than comparable reinforced concrete beams. However, cracks appeared early in the tests. (BPR abstract)
