The transverse part at the top of the wing plate, the longitudinal part in the middle of the web plate and the horseshoe bottom are the same as horseshoes, with an area of 22.5× 19.5. The parts on the T-beam are:

Upper wing plate, web plate (beam rib), horseshoe lower flange, (middle end) diaphragm, (dry) wet joint, expansion joint notch, etc. , drainage reserved hole, guardrail embedded steel bar, etc.

Extended data:

A beam with a T-shaped cross section. The protruding parts on both sides are called flanges, and the middle part is called beam ribs (or webs).

Because it is equivalent to digging out the concrete in the tensile area where the bending strength is invalid in the rectangular beam. Compared with the original rectangular bending strength, it can not only save concrete, but also reduce the self-weight of components and improve the span capacity.
