Form8Dot18DesignValueTransmissionLength2(l_pt: MM)

Bases: Formula

Class representing formula 8.18 for the calculation of design value 2 of the transmission length [\(l_{pt2}\)]. The less favourable of [\(l_{pt1}\)] or [\(l_{pt2}\)] has to be chosen depending on the design situation.

[\(l_{pt2}\)] design value 2 of the transmission length [\(mm\)].

EN 1992-1-1:2004 art.8.10.2.2(3) - Formula (8.18)

Parameters:

  • l_pt (MM) –

    [\(l_{pt}\)] Basic value of the transmission length [\(mm\)]. Use your own implementation for this value or use :class:Form8Dot16BasicTransmissionLength class.
