Hello everyone,
I need to know the following (and any others if I necessary) seismic design parameters for London (bearing capacity of soil: 50 kN/m². For now I only know this information) for a pre-design of a steel structure.
For Defining Vertical and Horizontal Response Spectrum Functions...
Hello everyone,
When I divide a frame permanently into pieces and then join them again I come up a problem: Sap2000 still counts deleted objects and says 7 (for example) objects selected instead of 1. Even if I delete that problematical element, sap2000 still counts it/them somehow. I tried to...
Hello everbody,
If I would like to hide ``some of the grid lines`` (not all of them), in grid system data I can chose `No` for them. It is okay. But when I have a lot of grids to hide, it takes so much time to do it one by one. Is there any quicker method for this?
Best Regards,
Hello everyone,
I have a question about CW purlin bolted connections in Tekla. I can not create it as I wish.
If I use Cold Rolled overlap (1) macro: It does not work properly with 2x4 bolts. It works only 2x2 bolts. If I use Rail Connection (70) macro, it does not work too. Rail connection...
Hello all,
I have a question about defining eartquake loads:
1) In some Etabs tutorials, directions are defined like in the first part of the picture (1) : X Dir, X Dir+Ecc, Y Dir+Ecc all selected in one load pattern.
2) And in some other examples there are 3 different Load Patterns: EX...
Hello everyone,
I need a handbook for ETABS (especially for designing of concrete structures) which will include different kind of examples (as detailed as possible) with newest versions (or at least after 2016) of the program.
If there is such a thick, helpful book, could you please tell me...
Hello all,
How should we specify following parameters? What must they be?
1- Seismic Design Categories = ?
2- Omega = ?
3- Cd = ?
I will be happy if someone help about it.
Best Regards,

Hello everybody,
Does anyone know that what the simple meaning of the following warning in ETABS is? Is it something crucial?
``The max. absolute changes in the EI and EA reduction factors is 0.2. For .. members, the reduction factor decreased by more than the negative tolerance of 0.01. Do...
Hello everybody,
In SAP2000, when I create a report with create report command, the reports becomes too long. But I create it thanks to advanced report writer it takes so much time.
I think, since CSI says so, it is possible to set up advanced report writer once like we wish and we can use it...
Hello everybody,
In SAP2000, I copy/replicate some structural elements and when I analyze structure again, I realize that SAP2000 had changed & assigned those copied & replicated frame elements into some other sections automatically. And just because of this, I have assign those frame sections...
Hello,
I think, secondary beam (composite beam) and steel deck directions in the attached picture are basically wrong and it will be better if I change the directions.
What is your opinions? I will be glad if you look at it share your experiences and help me.
Thank you already now.

Hello all,
When I want to run analysis after modelling and loadind etc., it is running and complete without any problem. But when I want to see detailed them command File\Last Analysis Run Log I can see folloving information in the middle of the long lists.
So what does it mean? Is there any...
Hello all,
I am a new ETABS user. When I design composite beams and a steel frames together, the final sections seems strange. I mean columns, composite beams and short beams seems smaller than usual, but long steel frame beams are bigger than usual. You can see following final sections and...
Hello all,
I would like to know how to define and assign earthquake, and wind loads etc. in SAFE? I cant see any option to describe loads definitely except surface loads in SAFE.
I know that it is possible to export all the loads from ETABS with model but I am not able to do it somehow. So, I...
