Truss shapes for underground tunnels.

Can we apply different Geometrical Truss shapes for
Underground Tunnels design?

Thanks & Regards,
Prashant S Akerkar

We have to check the Underground tunnel system design feasibility with Research and Development.

Can we Build Truss Architectural models for Underground tunnels design?

Isn't interesting?

Well at least you bothered to make some sort of reply to my post this time.

You will find folks wil help much more if you enter into a proper discussion/conversation with them.

That would mean starting by explaining what you are after in plenty of detail, appropriate to the complexity of the question.

And then by responding when someone takes the trouble to read it and puts their own effort into providing a detailed reply.

So what explain what you are trying to achieve, trusses are particularly awkward structures to use in tunnels.

Thanks.

Trusses Research and Development in Underground tunnels design.

This could be complex design but not awkward.

Since you know it all, why did you bother to ask?

Trusses are unsuitable because

1) They occupy (too much of) the bore of the tunnel

2) They are structurally usuitable because they are structures designed to resist the lateral loads and the bending they generate, not the radial compressive forces in tunnels.

3) Trusses are open frame structures that cannot by themselves prevent tunnel substrate material falling through.

Thanks for the information provided.

Civil Engineering challenges in constructing Different Truss geometrical shapes for underground tunnels design.

Can this be considered as a Research thesis project for Doctorate program?

Thanks & Regards,

You still haven't answered my question

What is the purpose of the truss?

That is what do you want the truss for ?

I cannot see how a truss can help you design a tunnel.

Do you now understand equilibrium?

Thanks.

Can this be considered as a research thesis project for Doctorate program specific to Civil or Mechanical engineering?

Thanks & Regards,
