Hi,
I have modeled symmetry structure in staad pro with symmetry loading but beam no:17 alone fails and have more unity ratio why??
i have attached model for reference below.../3162.rack.std
The structure is not stable, so you cannot trust the results reported as it leads to infinite displacements. You need to modify the supports so that the displacements would be reasonable and then check the utilization ratios.
Thankyou sir...
But this model is used for lifting purpose only ,
that y i give support on top member
otherwise i will give support in bottom member only sir.../
