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.

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.

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.

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

Multithreading meshing

Status: New Idea
by Active Contributor igos on ‎12-28-2012 08:51 AM

Everyone knows that make proper mesh for complex geometry on the first try is impossible.

Robot makes perfect mesh, but, unfortunatelly uses only one core of CPU, so process is quite long on powerful computers. 

Please, make multuthreading support for meshing and we can save a lot of precious hours :-)!

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.

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.

Please put back the EXPERT add on for the English package with the Retaining wall design, piles and pile cap design. this was very usefull. I don't know french so it is hard to install the french version and deal with it.

Dynamic Wind capabilities

Status: New Idea
by Active Contributor igos on ‎12-30-2012 12:56 AM

In some codes wind load is divided in two parts - dynamic and static. 

For example, in Russian Codes, the dynamic part of wind load depends on: static load, masses and natural frequency. 
Unfortunatelly, Robot hase no capabilities to calculate dynamic wind load automatically.

8 Kudos

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)

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

Quite long slabs on grade has irregular foundation pressure, thus they have to have irregularal elastic coefficient to calculate forces in slabs correctly.

Unfortunately, right now Robot has no capabilities to set non-constant elastic coefficient for the slabs.

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.

Since 1 december 2011 steel code SNiP II-23-81 not used in Ukraine.

Now this option is possible for French codes only. It would be great to implement general eurocode for wind loads (EVS-EN 1991-1-4:2005) for such calculation option.

Thanks.

I would be very useful to see a more detailed user manual with some complete step by step tutorials (especially RC buildings) as mentioned here

Also more verification manuals would be helpful.

Overstrength factor for capacity design Eurocode 8

Status: New Idea
by Product Support ‎04-23-2014 09:20 AM - edited ‎04-23-2014 09:21 AM

Eurocode 8 define an Overstrength factor that should be considered for elements design.
The consequence of this factor consideration, is described for instance in the following articles:
6.2.3, 5.4.2.2, 4.4.2.6, 5.2.2.2, 6.3.2 and 7.3.2 (more other articles may exists).
