It is an improved version of the ceh piece . Just like its predecessor, it is a ventilated piece thanks to an orifice that is made in the special supporting pieces of the girder. Also like the previous piece, it is originally calculated without the wing piece that functions as a parasol, although the data in this table correspond to those of the whole piece.
