NEVER exceeding 30 kN due to the tear of the ∅20 hole of the
diagonal. The maximum working load of the diagonals is given by the tearing of the hole.
5.1.8. HORIZONTAL BRACES MK
Two limit values are given below for the horizontal braces. The first value does not consider any working platform
installed on the braces hence they are only submitted to compression loads. The second value considers apart from
compression, the generation of bending moments along the brace due to working platforms.
For the first case and for any length of horizontal braces:
