Question
Dear Arshad khan
I am an Iranian student.I really need some guidance for my design project. I want to use Virendeel trusses in my design .My question is that how the ratio between span of columns and the height of beams is changing in concrete structure?
thanks

Answer
Hi Negar,

Basically you work out the total bending moment and shear, assuming that it is a solid beam, then design each segment of the truss to take the top and bottom chord tension/compression as well as bending due to the shear difference between one side of each square to the other- in other words- the difference in vertical forces.

It is a bit difficult to explain this without sketches, but maybe you get the idea. This website has some further info:
