Embodiment Construction
[0048] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.
[0049] see figure 1 A kind of three-span antinode engineering beam-transverse wave-three steel concrete composite T-shaped continuous beam of ~Fig. 7:
[0050] In this embodiment, the mid-span span L 中 is 60m, the span L of the two side spans 边 Both are 35m.
[0051] The main girder includes antinode beam 1, steel cross brace 14, steel diagonal brace 15 and concrete diaphragm 16. The wavelength on the corrugated steel web 11 is 160cm, the thickness of the corrugated steel plate is 1.4cm, and the wave height is 22cm. Plate 13 is 2.0cm thick and 60cm wide, and the lower flange plate 12 is 5.0cm thick and 100cm wide. At the bottom of every two antinode beams 1, welded H-shaped steel is used as cross brace 14 and diagonal brace 15, with a width of 30cm and ...
