Analysis and design of two way slab panels systems with or without drop panels or columns capitals, oginaly ARSA was created for the way that European structural Engineer are proceed and in the uses of construction in europe, means here by the fact that usually in europe RC buildings are made with cast in place sab on beam, but in North America particullary in the US and Canada two way slab system with drop panels are pratically the standard for High rise Buildings.
And actually the softwares that really help the engineers in their works are essentially :
3-ADAPT RC FLOOR with or whitout post tension (which is in my point of view the most powerfull of them)
In the case of ARSA, some work must be done to achieve the works that have been made fot the RC-plate modulus,because the way and the process that ARSA show the provided reinforcement are a little bit fastidious when comparing it with those softwares. Effectively, they allow the user to proced the analysis and the design by using the strip design procedure (betwwen line support) based on the direct design method instead of the FE method (which is very usefull in ARSA).
Drop panels, must be define also in a parametric way in ARSA, just because also the improvment that have been made in the same time in revit. I read recently that RobobAT POLSKA have created an extension for RSA to doing that,but there is any video where the users can visualise it.
1) Improvement in general acceleration when creating/viewing a model/ when changing loads etc.
2) Solver improvement - multhithreaded solvers (all)
1) It would be great if we could identify in a 2D model type of linear support (added to panel edge).for e.g. whether it is a concrete wall or masonry wall.
Right now it's not possible.
2) Would be excellent if you could put all the add-ins from forum into ARSA
3) More advanced "Phase mode"
4) Option like: Cut panel by/to other panel
1) Differential shortening of columns in tall buildings (at least steel one's) calculation
1) Composite structures design
2) Steelwork design - more types of connections for steel elements
Hi, it's been a long time that we are waiting for team developpement to improve the abality of ARSA pro, to perform real seismic analysis of RC Shear, for major codes design such as EC8, ACI and CSA A23.3, actually users of ARSA must search the solution by buying other tools or softwares made by other editors and unfortunatly, they are not provided the full solution for all the codes.They were an hope with Altiscad Intellishape but this company seems to be diseaper with this powerfull tools, instead of Intellishape we found that two products on which team developpment of ARSA can take some ideas to finally make this dream come to reality:
1-Design wall Expert made by PROEKSOFT which are perform the Design of RC Shear wall only for EC8
2-S-Concrete of SOFTEK wich unfortunnatly are doing it only for North American Codes (ACI and CSA : A23.3)
3- ECtools - Eurocodes Seismic Design a powerfull Greek Tool for Design and Analysis for RC et Masonry sections for EC2 and EC8 with bidirectional link only for SCIA pro Engineer and CSI ETABS
4-ETABS 2013 which some important improvments have been made for Design and analys check have been added recently for the design and analysis for RC shear wall for various codes and various hape.
5-Ram structural system which perform RC-shear wall design and analysis for gravity, wind and seismic loads for only USA & british standards
Those improvement for the four products can be visualised by clicking in the following links :
Based on this review, I think that ARSA team Developpment will find some ideas to complete this module asap
with best regards
it is easier to assign Reinforcement to the RC section so after analysis RSA can start design same as steel.
defining RC column C1 250x300 rectangle section and there will be Tab to enter design parameters (reinforcement, stirrups,..) so after running the model I can go and start designing immediatly and see failing ratios
Robot Structural Analysis 2014 still does not contain CSA O86-09 Code for wood structure. Is there a reason why Autodesk would not incorporate this? Is the Canadian market too small? Is there a timeframe for incorporating?
ENVELOPE OF FORCES IN JOINTS AND SUPPORTS, ONLY MAX EN MIN OF ALL COMBINATIONS
It is important for some design activities. Robot 2014 shows envelope for combination but doesn't show a table or list of Max and min of all combinations.
INTERACTION DIAGRAMS OF WALLS
It would be very grateful if were possible to show interaction diagrams for walls and to configure the reinforcement.
INTERACTION DIAGRAMS OF WALLS
It would be very grateful if were possible to configure an arbitrary reinforcement.
It would be very helpfull to be able to get panel cuts in table and the ability to copy a panel cut. For instance if you have different models with the same geometry it would be fast if you where able to copy panel cuts into a model.
And also to see the results from more than 14 panel cuts at a time.
Also it would help a lot if you could get more than one result at a time. If you need to check both top and bottom envelope.
Few are the softwares, if not one or two, that computes the shortening and differentiel shortening of vertical elements. This issue is mainly encountered in high rise buildings (greater than 25 floors: concrete or steel structures) where a large core is povided at center and columns at periphery of tower or when a building is constituted of a tower over a podium of larger footprint with no expansion joints.
The elastic shortening and corresponding forces computed from elastic analysis are not the ones encountered in reality and are always overestimated and can lead to conflicts with third party reviewers.
Instead engineer should compute the instantaneous shortening, shortening due to creep and shrinkage with around 20 parameters to account for.
For reference refer to ACI209R and Column shortening in tall structures – prediction and compensation” by Mark Fintel, S.K.Ghosh & Hal Lyengar.
It would be interesting if Autodesk includes a tool to compute these deformations in the futur versions.
I have been looking at Robot for several years now. I tried the demo in 2011 and 2012. I am a long-time user of Autodesk products (Civil 3D, Architecture, ADR) and I am attracted by Robot because it is an Autodesk product now.
Each time I look at Robot I get the impression that not much is happening in development and that Robot is neglected by Autodesk. There are no updated manuals or tutorials or support or training seminars and the GUI has no relation to other Autodesk products and does not have the quality feel of Architecture.
Autodesk has a huge opportunity to take the lead among the likes of RISA, Ram, S-Frame, and SAP2000 with a comprehensive user friendly structural design/analysis package that integrates seamlessly with Revit and Autocad. For my part I am looking for some leadership and innovation and committment from Autodesk to this venture.
