You were attempting to do a Nonlinear Cable Analysis but there was no pretension load defined which is essential. I added a pretension of 10KN ( you may change as needed). The bigger question is whether the nonlinear cable analysis is required or not. Are these members that you assigned as cables, really cable members or are these rods ? If these are rods you may as well model these as TRUSS. Also when you are using a nonlinear cable analysis, each load case has to be a complete case by itself with selfweight and all components. You should not do a cable analysis with just the wind load ( for example load case 7 to 14 ). Also if you go with a nonlinear cable analysis, your load combinations should be replaced by REPEAT LOADs. These can be very easily handled through the command editor as explained for the load case 15 below

LOAD COMBINATION :

…

LOAD COMB 15 DL+RL

5 1.0 6 1.0

 

REPEAT LOAD :

…

LOAD 15 DL+RL

REPEAT LOAD

5 1.0 6 1.0

A partly modified file is attached for your reference. Hop this will give you some direction.

2068.Structure1.std

But how can i define pure cable instead of defining rod. i couldn't find any option of defining cable. Can i define rod and assigning it as tension member to get the effect of cable.

There are few in-build standard cable sections already added in Staad section database. You need to configure the section profile table for this.
Please see the link below.

communities.bentley.com/.../366848

However, I don't see any much of difference if you use the rod section (instead of standard cable section) and assign them as "Tension Only" member . The behavior of this section is same as the cable section which is supposed to only handle the tension.
