Stress-laminated timber bridge deck cross section


I am trying to make a cross section in SOFiPLUS of a timber bridge deck consisting of 80 glulam beams (each 119 mm width by 400 mm height) stress-laminated by a steel tensioning wire.
The timber material is GL30h.

I am able to outline boundaries for the 80 glulam beams next to eachother, but don’t know how to proceed with the tensioning wire.

Does anyone have any tips or know how to implement/make the tensioning wire in SOFiPLUS or are there any workarounds?
