Structural feedback – BIG ideas

This feedback forum is for your magnificent ideas for Oasys Structural software: major new features, significant changes to existing functionality, – suggestions that will impact on our development plan. These will be considered and prioritized in consultation with the Regional Panel.

You have 20 votes to distribute as you wish. You can reallocate votes at any time. Votes are released back into your pool when an item is completed (or declined).

How can we improve Oasys Structural software in a BIG way?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  1. GSA storey loading

    * Introduce a 'Storey Load" module ( load case | Fx | Fy | Fz? | Mzz ).
    * Modify the existing 'Equivalent Static / Accidental Torsion' tool so that rether than a set of node loads it populates this new table.
    * Treat the 'Storey Loads' in the same way as grid loads (ie they get expanded to node loads when the analysis is run which is currently the second part of the 'Equivalent Static / Accidental Torsion' process ).

    • GSA Save As with Specificed Results (COM)

      When using large GSA models it would be beneficial to be able to save selected results via COM API.

      • GSA entity sub-grouping / components

        Entities can be assigned a sub-group, e.g. 1.2.3.4
        Sub-groups can be up to four tier: Group; Assembly; Part; Component
        Sub-groups can be assigned a (unique) name, e.g. "wheels"."wheel 1"."spokes"."spokes left"
        Sub-groups can be referenced in lists, e.g. #1.2.3.4 or "wheel 1".
        Consider tiered entity ref, i.e. instead of element ref. 12 being in group 1.2.3.4, assign element ref. as 1.2.3.4
        Sub-groups can be assigned to nodes, elements, members, lines, areas, regions
        Quick visibility filtering based on sub-groups

        • SLS crack width limit reinforcement

          I would be very interested in a function similar to GSA’s RCslab, but which could be used to check SLS load combinations for specified limiting crack widths. This may be by “round-tripping” with ADSEC if necessary.

          We would probably need a way for ADSEC to disregard excessive crack widths that are reported at notional edges of wall / slab sections if a chosen bar pattern does not fit nicely with the standard typical metre width. I assume that the implementation would need more user input / interaction than RCslab.

          The reason for the request is that a semi-manual process of…

              • RC design add in for Excel to access Adsec design capability

                Create an Excel Add In to access Adsec concrete design capability in a spreadsheet. (The steel one is fantastic)
                We all need bespoke design tools on occasion, and rather than creating new coding for design we should be able to access a well maintained database of RC design coding.
                (There is OvaSEA, but this is doubling up Arup resources to codify concrete design. Currently, it also does not access as many codes as Adsec)

                • improve revit link

                  The amount of processing needed on a GSA model of a slab and wall structure once it has been exported from Revit means that the models quickly diverge. The goal should be to maintain a single (BIM) model so that any changes in the geometry (Revit) model can be quickly exported to create a usable GSA model.

                  Detailed notes from a GSA User (with no Revit experience) on the issues from a recent complex 3D model will be attached as a comment on this idea.

                    * Add graphical representation of bar arrangement
                    * Provide links to AdSec and ADC
                    - replacemenet for HK-BEAM (i.e. include batch processing)

                      • GSA - Split 2D elements at existing nodes

                        A command to split 2D elements if any extra nodes lie on its plane/edge to enable the connection between the extra nodes and the 2D element.

                        Example: In the attached image, Element-1959 has two extra nodes- 3064 and 3160 lie on its edge. It would be useful to have a command to split element-1959 considering these extra nodes as part of the newly generated element topology.

                          • GSA stadia crowd dynamic analysis as per the latest IStructE guidelines

                            New guidelines for carrying out performance-based analysis of stadia grandstands subject to crowd loading were published at the start of 2009. There are two different approaches to carrying out this analysis, one of which is not possible in GSA at present because viscous dampers cannot be modelled but the other could potentially be incorporated into GSA. We have funded research in this area in the Northwest over the last eight years and have a (quite slow at present) Matlab script which can do this analysis given some modal and node data from GSA (read into Matlab using .csv files). It…
