The use of open double T beams that is formed with double T beam no. 70 (the height of the open one is 104 cm) reduces the cross sectional area in a weakened spot, but virtually it does not influence the strength and durability of the material.

Savings on each spans, such as CRP, will be 33.6 - 263 thous. grn. (considering the price of 1 ton of final product 29 thous. grn.). Originality. Research allows making next step in material saving and use of open double T beams for spans in the whole. Practical value. The obtained results give us possibility to make a number of conclusions that allow us to become more familiar and more practical with the use of open double T beams for spans of floating bridges.http://stp.diit.edu.ua/article/view/23814/21960railway bridgesfloating bridgesopen double T beamsspansmetal savingbridge engineering progress |
