Hello everyone.

I am trying to perform the fatigue design of a post tensioned concrete bridge and I am having some trouble defining the fatigue load train FLM3.

According to EN 1991-2 4.6.4 (3), if the maximum span length of a bridge is ≥ 40m we have to take into account two vehicles in the same traffic lane with different self weight in a distance between those two vehicles >40m

Is it possible to define this load train in sofiload?

Thanks in advance

Hi,

yes, you can define a user loadtrain (TRAI user) with point loads TRPL.
With TRPL … DIST MIN A 40[m] a minimum distance of 40 m between the point loads of the first vehicle and the second vehicle can be defined.
