Hi..

While design the Combined foundation in STAAD ADVANCE FDN,  how Can we omit the pedestal design? I have modelled the Pedestal in STAAD Pro and then I run the STAAD ADVANCED FDN to design combined foundation but while designing the foundation, software by default design the pedestal. I am interested to avoid the pedestal design in ADVANCE FOUNDATION.

I am attaching the File for your reference.

Thanks,

I defined master and slave nodes to connect two structures, one supported the other; so the M/S is the link between the two structures. why after running STAAD I got different displacement at these linked nodes? is there a better approach to model the link between these two structures, since I have notice the result stresses are different in members than the result of the two separate structures when they were modeled separately.

Hello,

How does RAM calculate the Moments in the Controlling Combined Column Loads section of the gravity column report? I'm hoping to understand why the moment in the output reports is nearly zero, rather than equaling the beam load multiplied by the column eccentricity, even for dead loads at an end column. Attached is one of the gravity column reports. I've looked at the following FAQ page, but it doesn't quite explain how the reported moments in the column are calculated: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/2055/ram-steel-columns-faq

Any thoughts are appreciated!

In checking the seismic provisions for BRBF columns, I have a number of columns that are failing the required strength based on E amplified by Omega_o for compression.  The Pu for compression in each case is some extreme value that appears to be an error.  This is happening in random column segments throughout the model.  It appears to be isolated to D1.4a(b) in compression.  Sample output attached for reference. 

I have been model the plate ,base on same thickness same load, but different mesh size as show on the picture. The result of bending moment are differ (shown on picture). I want to get bending moment value to design reinforcement rebar, but i am not sure which the bending moment result can be get design. Anyone please to describe and get example about that. So for example RC.design like .... As = M/fsjd, ***** I was calculated the strip width for compare bending moment and not same .... 9.03x0.75 = 6.78 t.m ≠  4.88x1.5 =7.32 t.m ..... 5.91x0.75=4.44 t.m. ≠  1.73x1.50=2.59 t.m.

Thank you.

Hi all. For extracting values of bending moment, when I'm checking in the bending moment diagram, the support moments (hogging) are + and span moments (sagging) are -. But when I'm checking in report, the same value reverses sign. i have to additionally copy the same columns again and reverse the sign. I was hoping to automate in excel to extract max support moments (excel : max(values)) and max span moments (min(values)). Please suggest a way out to minimize effort.

How do I export my model in Ram Structures to a Revit file.

Dear sir,

good day,

I design the attached structure in two ways. when I design it without considering the concrete plate it gives very less utilization ratio? and when I design it without considering the concrete plates on the top of beam it is getting the failure. Kindly advice me which way is better .should I consider the concrete plate on top of the beam or not?

hi,

i am using IS1893 2016 Response spectrum analysis with DEC=1 and Ecc=0.05 with rigid diaphram definition.

after running the analysis i found that all the horizontal bracing in the model are not designed / no forces transferred 

due to rigid diaphram definition.

I have used the following syntak to specify diaphram.

FLOOR DIAPHRAGM
DIA 1 TYPE RIG YR 5.4 5.6

Can you please let me know how to design the horizontal brace members when using IS1893 resp spectrum analysis with torsion in Staad.

Hi,

When I try to install RAM Connection V13 I get prompt to update Window KB. But When I click to update, I get a message that it's already updated. So the installation was failed. Please help. Thanks!

Hello,

I have a podium building, 2 concrete flat slab levels supporting 5 wood (other) load bearing wall levels.  It's a large building, like city block sized.  The model runs fine in Frame, but it takes over 7 minutes.  We export the results from Frame to design spreadsheets to design the wood.  That part seems to be going fine.

The main problem I'm having is that I can't get the model to run in Concrete in a reasonable amount of time.  The slabs will be designed separately in Concept, but I need Concrete to run to design the lower level concrete columns and shear walls.  But I can't get there because I can't get through Concrete gravity analysis.  At first I ran it and it took hours to get through not even 2 of 7 levels and I cancelled it.  Seems to get stuck in "Creating nodal loads from reactions".  I changed a few analysis options to try to make it run better and ran again.  It did seem to run slightly faster but then I got an error that a node is too close to itself (same node number, 0.000” apart, wouldn’t you know) and to crapped out.  But even if it hadn’t it was going to take an unreasonable amount of time to run.  Probably well over an hour.  So my first question is, do I have something set wrong that it’s running this way?  If not, is there anything I can do to dumb down or simplify the wood levels to get it to run reasonably?

My other issue is regarding the f1 factor for LRFD load combos.  In generating combos is looks like we have only one chance to set it.  But my podium building has one level of parking at the bottom (LL=40psf), then the podium level above has the equivalent of 200 psf from 5 levels.  Setting f1 to 1.00 for the entire structure because 40 of 240 psf is parking would be overly penalizing it.  But using 0.5 would go against the code instruction to use 1.0 for parking garages.  Is there any way to set it to 1.00 just for the garage level?  How is this is typically handled in buildings that are only partially garage?  Seems like it could be set up to use 0.5 automatically for reducible LL and 1.0 for un-reducible, since this is the same distinction in the code (over 100 psf and garages) and RAM already has a LL tag for reduce/unreduce.  

Thank you,

I am modelling existing steel , portal frame building, loaded with heavy services. I know that Microstran can genarate nodal mass based on the imputed loading. How do I do that? Does it allow for the accidental eccentricity? Is there my manual i can use to help me to preform this actions?

I UNDERSTAND IN THE DIRECT ANALYSIS K=1 BUT WHAT ABOUT THE PARAMETERS LY, LZ TO DEFINE THE EFFECTIVE LENGTHS EFFECTIVELY. I HAVE A LATTICE TRUSS OF 25 M SPAN  DEPT 2M WITH LACING @ 2M C/C.

I AM DOING DIRECT ANALYSIS. I AM GIVING PARAMETER LY=25M AND  LZ=2M WITHOUT ANY KZ KY VALUES FOR BOTH TOP AND BOTTOM CHORD. IS THAT CORRECT? CAN ANYONE CONFIRM?

I GET THE FOLLOWING WARNING WHILE DOING SEISMIC ANALYSIS. I UNDERSTAND I CAN IGNORE THE WARNING. BUT CAN I SUPPRESS IT?

Dear All,

My doubt is that moment release to be done only in Z direction for the secondary beam? because in staad help manual it is showing that each individual member will takes the local axis so for every beam whether it may be in X axis or in Z axis moment to be released in Z direction only? or else moment release to be done based on the co ordinate axis that is it may be X or Z. If so what will be the moment release for a secondary beam which is parallel to X axis and a secondary beam parallel to Z axis?

Hello!!

Can someone tell  me when the latest edition of STAAD connect edition will be released addressing the defects in design of Steel tapered sections as per AISC 360-16 code. An exact date would be highly appreciated.

Please do reply.We are being pressurized by our customers to design as per AISC 360-16.

Thank you.

Hello,

I am designing 2 knee braces connected to a single column to c.arry a unit via hanger rods. The vertical legs of knee braces will be welded to the column but as STAAD doesn't take that connection into account, I created a similar condition with a beam. Can someone please let me know if this is the right approach for this model. The knee braces have 300 lbs load at its end as can be seen in the model.
