Dear Madam, The following points may be noted:1. DM factor of seismic load definition shall be corrected as 0.05 instead of 5 (error in default value in older STAAD versions)2. GLD or EUDL parameter...

I have attached another modelling Structure 3.It's same as structure 2 (from General option) but I don't use offset.I think if I use offset it will be incorrect because without offset the column has...

Sorry, I mean there is "no" deflection or moment at the L-shaped column meaning those columns is aligned (concentric).

Kris:1. Shouldn’t Eq. H3-6 be 0.959+(0.048+0.288)^2=1.072 (combined flexure, shear and torsion)?2. Output said MOMENT CAPACITY UNIT: KIP FEET and torsion is moment so I thought that Torsion Capacity...
