A ductile composite bridge deck composed of T-section steel
A T-section steel and composite bridge technology, applied in bridges, bridge parts, bridge construction, etc., can solve problems such as affecting the corrosion resistance and durability of bridge decks, increasing bridge structural repair and maintenance costs, and affecting structural fatigue performance. Avoid binding steel mesh, improve out-of-plane stability, and improve construction efficiency

Embodiment Construction
[0033] Embodiments of the ductile composite bridge deck composed of T-section steel of the present invention will be described in detail below with reference to the accompanying drawings.
[0034] like figure 1 and figure 2 As shown, a ductile composite bridge deck composed of T-shaped steel includes the following components: hot-rolled T-shaped steel 1 , transverse reinforcement 2 , and ultra-high ductile concrete 4 .
[0035] like image 3 As shown, the hot-rolled T-shaped steels 1 are continuously placed side by side in the transverse direction of the bridge deck, and the adjacent hot-rolled T-shaped steels 1 are welded by two fillet welds 3 to form a bridge deck steel frame. 5 is the longitudinal direction of the bridge deck.
[0036] like Figure 4 As shown, the lower flange of the hot-rolled T-section steel 1 is longer, which acts as an external stiffening effect on the plate surface; the upper flange of the hot-rolled T-section steel 1 is shorter and has a row of r...
