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.
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.
For some calculations sometimes we need to take into account different Young modulus depending of the nature of load cases. This is expected for a single model, to avoid duplication of model data. We see such requirements in Eurocode and also AISC codes.
Working on my last project (it's an concrete structure, about 150 000 nodes and 170 000 FE-s) I was extremely annoyed by Robot Str 2013 general performance. For example, changing an load value is operation with time consumption not less that half of minute on quite modern hardware (core i7 etc.). Changing values in tables is not much quicker...
I understand that you can recommend to use diaphagms instead shell etc, but in general - performance of Robot is not the best one, I can say the worst one. Now it is 2013 year and yes, sometimes we have to analyse and calculate models with more than 3 bars...
Here I do not speak of calculating time, meshing time - it's only problem of general performance, for example, changing load values in large scale models. So, my Idea is to optimize code (I'm fully understand that it can take a lot of time) to make Robot works much quicker.
The section builder tool is very good, although there are some problems.
- the naming convention is USELESS. only being able to give a 4 letter description is very limiting.
- not being able to save a new profile as a concrete beam is limiting. the section definition only allows reduction of moment of inertia for steel sections, and any user defined section can only be used as a "steel" section.
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).
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, 22.214.171.124, 126.96.36.199, 188.8.131.52, 6.3.2 and 7.3.2 (more other articles may exists).
I think everyone have tryed to get ennoyed about how the plates seems to turn upside down, sideway or inside out when you go into Provided reinforcement maps for plates just fells allraund random. I whould love to have every plate turn up the same way, Like local system is allways followed, i dont care about the detalies, aslong as the same rule is allways followed, because then i whould be able to not have to think about what side of the wall im lokking at, in what direction. I can just adjust my local system for all the walls, whits i do anyway.
Im sure this is and easy function to fix, so thanks on advance
My proposal is very easy to do. It could be useful if, in the parameter for modal Analysis, there will be add a tool to automatically convert loads to mass. In a lot of coutry code settings, the load to mass conversion coefficient is equal to psi2 (quasi permanent load cobination factor), well, it's incredibly easy to make this automatically.
