The Study of Diaphragm Beam Influence to Load Transverse Distribution of T-Beam Bridge
Diaphragm beam has grate influence to load transverse distribution factors of T-beam bridge. Two steel T-beam bridge models were made in this article, one have diaphragm beam and the other one have not. Concentrated load was applied to both of them, and mechanical analysis of the T-beam bridge model was carried out by finite element software. Compared with experiment data and theoretical data, it shows that: when the concentrated load was applied to mid-span of 1#,2# and 3# beam of the two kind bridges, the 1#,2# and 3# beam load transverse distribution factors of T-beam bridge without diaphragm beam is larger than that of T-beam bridge with diaphragm beam by 19.3%~23.2%、25.3%~30.6% and 48.1%~50.1% respectively.
