RAM Elements Double Angle in Compression with AISC slenderness computation is off.
I am modeling a truss with LL angle chords. The model is computing a very very high slenderness ratio and in turn is returning a very low capacity for the chord compression. Can someone provide some insight on what how RAM is computing the slenderness…

How to model stepped column in RAM SS?
I am trying to model a single larger precast column that basically gets split in order to support a steel truss on one side and a precast column with a moment frame on the other. How would you recommend we model this condition?
My best idea would be…

How can I support the truss by two cable and bottom support?
Hello all,
I have been trying to model a truss. I have two bottom support, it can be fully fixed or partially fixed and I have two cable connection at the top. But this cable member should not take any compression, since I have Wind suction in that…

Unusual behaviour of truss members
We experience this problem when we assign "Truss member" to cross bracing. The structural behaviour is normal without "Truss member" specs assigned.

Modelling Existing Building - Excessive Horizontal Node Displacement where Column meets Truss
Hello, I am modelling an existing building, which has a number of columns which connect to the bottom of trusses at approximately midspan. These Columns are at the building face where the wind will act on them. In all load cases where I have generated…
Error in Design - Simple Steel Flat Truss
Hello All,
I have modeled a simple steel truss to check my hand calculations. When viewing the global status of the model, the diagonal members are shown to have "Errors in Design."
The members all have ratios from 1.84 to 3.6.
However, my…
