I have modelled s transmission tower as STAAD SPACE and trying to design using IS 802 code. I am getting the warnings as below,
WARNING : THE MEMBER 3 IS NOT A TRUSS MEMBER.
THIS MEMBER HAS BEEN DESIGNED CONSIDERING AXIAL FORCE ONLY.

What will be the solution here?

Thanks for submitting the case with us. As per implementation of IS 802 code in STAAD, the code checking is based on the IS:802 (1995) requirements. Axial forces at two ends of the members are utilized for the code checking calculations.Please note, Shear and bending forces are not considered in design per IS:802 as this code has no provisions for either. If a member design per IS:802 is specified for a member without a TRUSS specification within a model that is not a STAAD TRUSS, then a warning is given in the analysis results file that only axial forces are considered. Here, as you have modelled the structure as STAAD SPACE, hence the warning is shown.
If you change the first line of the input file to STAAD TRUSS from STAAD SPACE, this warning will not be shown.
