Automatic Wind Load Generation as per ASCE

Status: New Idea
by it on ‎09-15-2014 07:23 PM

I would use this product more often if it include automatic wind load generation in accordance with latesT ASCE provisions. Also would like to see American Codes for wood and aluminum desing.

Offsets in Robot

Status: New Idea
by Distinguished Contributor Tuctas on ‎09-05-2014 09:18 AM

Offsets have to be replaced with another option in which rigid links will be automatically defined in proper locations, because the way that they are used right now in Robot is not convenient at all and it is causes many simulation problems... Especially in RC structures, where it is immediate to consider non "centerlined" connections between members, Robot has to be improved about this issue.

Bending moment diagrams

Status: New Idea
by jaikeshant on ‎09-04-2014 11:40 PM

I am trying to find out why RSA produces the bending moment diagram for a simply supported beam with a UDL on the begative side of the graph, as seen in the attachment. 

 

Based on my calculations, the bedning moment diagram should be on the positive side of the diagram.

 

Is there an elementary setting for sign convention I am missing?

Improve buckling analysis for seel beams

Status: New Idea
by Contributor iegia on ‎09-03-2014 05:05 AM

Improve flexural, torsional, flexural-torsional, lateral-torsional buckling analysis in steel beams, adding Warping torsional degree of freedom for steel beams.

There are some software  (STABLAB, SOFISTIK) use a beam finite element directly developed for the analysis of thin-walled spatial steel members. This element is based on Vlasov theory and has 7 degree of freedom at each node (3 displacements, 3 rotations and 1 warping freedom).  You don't need to built a model based in shell elements to realize the buckling analysis of the steel profiles.

Section Designer

Status: New Idea
by Mentor on ‎08-27-2014 06:45 AM

I suggest to strengthen the Section Designer.

I would like to be entered:

- The diagram Moment - Curvature

- The analysis of the section of the fire (thermal mapping and verification sectional according to the rules)

 

for composite structures, RC and steel.

 

Thank you

The module generates the loads incorrectly if the panels that are not parallel to the global coordinate system! Map pressure is valid but final loads generated on panels are wrong - have a much underestimated values. It wuld be nice to fixed the problem in new service pack.

MASTER-SLAVE STEEL JOINT ENGINE

Status: New Idea
by Mentor on ‎08-24-2014 03:30 PM

It will be powerful if will be added, in the steel connection tool, the option to auto detect the identical joint present in the whole structure, or define from selection a region where the identical joint have to be applied.
Once Robot find the group of "SAME STEEL CONNECTION PROPERTIES" the user can create the joint using the actual definition present in Robot. This definition will be applied to all the member of family, and all of it depend by only one "master definition", each changes on its parameters (for example bolt class or plate thickness) will be applied to all the joints of the family, avoiding the "time consuming" manual definition and calculation of each connection and, overall, the possible mistake in manual data input.
After you have defined the steel connection family, the user can run the code checking of the family, Robot automatically calculate all the steel connection present in the family and plot the report of the top ratio one.
This tool, added to an improvement of steel connection type (for exaple more beam to beam connection type) can be made easily, the calculation engine is the same of robot, the report generation is the same of robot, only the grouping engine tool have to be programmed, but can be partially copied from the spread footing dimensioning.
Please give kudos to this idea.
Greetings at all

I think it would be helpful if with Robot we could calculate (against wind and earthquake) and detail the roof anchorage between a steel or timber roof and concrete or masonry walls.

This could be expanded in joints between different materials eg a column which is of concrete till a certain height and above there is a steel column.

Thank you

Robot Structural parameters will have to regions like Mexico or any later versions or any package that is installed in the program that contains it?

It would be great if automatic wind/snow load was added for 3D Structures according to Eurocode 1.
It's sad that this option is only available only in 2D.

Dealing with bigger models

Status: New Idea
by Valued Contributor mgaafar on ‎07-26-2014 11:46 AM

Hi, So I noticed that as the model gets bigger in size due to big number of elements the model tends to be slower and slower to manage. at this point, and editing in the model will consume lots of time.

I think this happens because RSA saves all the information in one file and as the user edit the model, RSA saves the information in its location in the file and by the time RSA finds the location in the file and edit the code and regenerate that takes a significant time in some cases..

any file has total number of node more than 20,000 things start to get slower and slower.

I hope the programmers can find an algorithm or a way to speed up working with large files. (may be by splitting iinput file into different files or something similar).

Thanks

AUTO OPTIMIZATION AS SAP

Status: New Idea
by Mentor on ‎07-04-2014 04:57 AM
Hi everyone,<br><br>It could be absolutely powerful if will be added the option to optimize each bar in the code check, as happened in SAP, in this way the user can define a family of cross section and each bar can be searched in this family. After the first optimization run it is possible to group some member into a "SAME-CROSS-SECTION" family and go on with the optimization and the checking of all the bars.<br><br>Greerings

Warning with load display ON

Status: New Idea
by nishchint ‎07-03-2014 03:26 AM - edited ‎07-03-2014 03:35 AM

Hi

It will be nice if a warning is displayed once the load display is ON and the user types in new range of loads/combinations in the box.

The warning could warn the user that it "might take a long time to display all the loads together graphically."

 

Maybe I am the only one, but i have managed to crash my system more than a few times by not realising that i have the loads display set to ON and then typed in a range of 500 combinations in the load/combination sleection box. :-).

 

As a side note, making the "escape" key  more reliable to abort any/all activities being carried by robot could also be a solution for situations when things are typed without realising the consequences. Thanks

 

Regards

Good day!

I am final year Civil engineering student at KGASU (Kazan, Russian Federation) , as my final year project i did code comparision between ACI, EC2, and Sp . 
but unfortunately Autodesk Robot structural analysis doesn calculate beam accroding to SP 63.13330.2012. 

Please make this option available for the next releases. 

 

In advance Many thanks

The idea registered to probe the users' opinion on the usability of such feature:

 

The possibility to assign different Young modulus of concrete for different load cases to be used during analysis

Some examples:

  • Instantaneous (live load)
  • Long term (self weight)
  • Medium (n=15)
  • Medium seismic = instantaneous/2 (Seismic EC8)

Adding beam restraints/internal bracings

Status: New Idea
by enda.farrell1 on ‎05-27-2014 06:02 PM

Hi,

 

It would be very beneficial to make the input and display of beam restraints more user friendly as the current method is not straight forward. This is the only reason I avoid using Robot for Portal Frame design.

 

I have attached a pdf screenshot from another program which is the easiest I have come across to input beam restraints. It also shows an overall structure view of the restraints so it is easy to see if there is a restraint out of place. I find it can be easy to get member restraints backwards or upside down without this view. Just a tick box in display to show restraints would be fine.

 

Setting restraint points is much quicker because its done from one dialog box for all restraints. This may be something which could be developed in the short term with excel using macros and linked to Robot by creating a new Member Type? 

 

Please see http://forums.autodesk.com/t5/Robot-Structural-Analysis/Adding-beam-restraints-internal-bracings/m-p... for initial discussion on the above.

 

Thanks

Enda

Armenian standards for earthquake-resistant construction

Status: New Idea
by Contributor Nairi85 ‎05-27-2014 07:51 AM - edited ‎05-27-2014 08:01 AM

Good day! My name Nairi I constructor of Armenia. Appeal to developers Robot Structural Analysis with a huge request to pay attention to the promising market of Armenia .

In this regard, on behalf of numerous engineers ask add to the base Robot Armenian standards for seismic design : SNRA II-2.02- 2006 (СНРА II-2.02-2006).

We have many areas there is a probability of more than 12 earthquakes epicenter balls , and 4 types of soil on the seismic characteristics. And the rest of design standards similar to the Russian norms . So I think that just a matter of deciding integration SNRA II-2.02- 2006 Robot will have a great demand in our region.

In advance many thanks.
