Hi Amitava! Thanks for the immediate response. Check the beam under wheel load, Beam nos. 74, 211, 108, 142 &176 and 93, 230, 127, 161 & 195. Design ratio at the opposite beam should be equal but in the actual result it was not. As you will notice the platform is divided into 4 segments (0.2m, 0.3m & 1.3m) this is due to inconsistent section that will occur at 0.3m length which we are going to stiffened via bottom plate. Thanks Master mac
In the attached image you can find the member numbers you have mentioned and the corresponding utility ratios. Though all of them have failed, but we can see the utility ratios are same. Can you please tell what value you are getting.

Please see attached image and can you please send me the STAAD input file if you do some changes?I'm wondering why i am still getting not the same result as you.
Thanks,
