0.75xIequiv is no longer the standard to reduce the moment of inertia for composite sections controlled by deflection. How is RAM SS accommodating this revision?

Beam-Grider Connection from 2 sides, sharing bolts
For beam-girder connection design, how do you prompt RAM for cases where there are beams on opposite sides of the girder that share the same bolts. i.e. clip angles on either same sharing bolts, with unique loadings from each side?

Beams in Two-Way Slabs in Banded Direction
Is it acceptable based on ACI 318 18.1.3 to assign the column strip width of a beam in the banded direction of a two-way slab as "full width"? I've seen several recommendations that you should only consider the full flange width for the axial compression calculation only, but that for flexural design one should really be using the effective flange limitations of 8.12.

Seismic Loading
Can someone please give me the STAAD input text for seismic to UBC and to BS EN 1998 - I find the STAAD help editor difficult to follow.
I am assuming that I will use CQC for the modal analysis, but what about SRSS etc.
In the example I have pulled together, I get 85% mass participation after 6 modes - how do I increase the number of modes in order to raise the mass participation to what I think I need of around 97%
Thanks

RAM Concept - Shear Wall Strip Footing Modelling
I'd like to explore the capabilities of RAM Concept in designing strip footings for shear walls.
I've set up a 'mat foundation' model with area springs representing the soil stiffness. I've then modeled a beam (strip footing) and the wall over.
What is the best way to model the shear wall forces? Should you model a horizontal shear force at the top of the wall to replicate the moment in the wall? For example modelling a 1000 kN point load at 4m above the slab surface to replicate a 4000 kNm bending moment?
Any suggestions would be much appreciated. Thanks.

Staad Foundation V8.0.1.33 flexure moment calculations issue
(Please visit the site to view this file)
unable to get similar results for different thicknesses, tried with 375mm, 400mm, 425 mm , for 375mm and 425mm they are ok, when trying with 400mm moments are exponentially increased, Can somebody help in solving this problem,

RAM Foundation reinforcing question
I have a fairly small, lightly loaded foundation that Ram Foundation is saying needs an excessive amount of steel - unless I'm missing a reason why.
ACI318-02, DL = 23.21k, LL = 22.99k, Lr = 4.26k
It is telling me that I need 4.06 sq in of steel per Section 7.12 (Shrinkage and Temperature).
Am I missing something here? (Also, on my larger, heavily loaded footings, it is also saying 7.12 is the code reference for design here too when moment is controlling this one.) Is this just a bad reference?

How to Model (2) columns bolted together.
Hello,
I am currently modeling a large structure that consists of a large building column and a crane column being bolted together every 24" o.c.
My question is how to properly model this situation in Staad.
I did try using pin connected angles every 2' but this did not seem to affect the design.
Next I tried some moment connected W beams every 20' and that has shown improvement but some of these connecting beams have failed unity. I am not sure if using this method is an accurate representation of the 2 columns being bolted together, and if so how to choose the members and spacing that I can accurately reflect real conditions and therefore design the bolts and spacing needed.
Thanks for any advice.
