Automatic detectin of slabs' contours and drawing them by :
one click, if distributions of loads is two ways ( same funtion exists already in CBS ).
one click + direction ( x , y or specified ) for slabs with one way distribution of loads.
at least we are sure that slabs will be connected to its contours.
Once you have calculated the members, you sort them by its working ratio, but in very big structures if you want to know which bar/s are the worst, you have to type manually its number on the bar box to select them and know where in the structure they are.
It would be much more handy if you could highlight the bars directly from this table.
There is a big weakness in the software wiht this topic.
It would be really useful if the user could "draw" any thin walled secction shape in the "section definition" module and after this secction is correctly checked (class 4, effective properties etc.)
It would be nice for Robot to correctly calculate the stiffness for beams that do not have the NA coincident with the slab NA. Using offsets give the problems of additional tension/compression forces that are not displayed in the moment maps and manually modifying the E for beams is a pain when there are a lot of different situations.
It will be very usefull to be able to view in the Results - Table of Sories the value of Alpha_cr coefficient (αcr) according to EC3 (chapter 5.2), in order to make the dicision if it is needed to take in to account second order effects or not.
Problem: In some cases it is desirable with different parameters for different analysis types in a structure. Examples could be:
- A structure where you want different releases in the static model than in the earthquake model
- A structure where you want different load to mass conversions for different cases
Currently, I often find myself saving different instances of a model. This means that changing geometry becomes time-consuming as each instance must be updated.
Solution: Allowing the model to branch, so that eg. one geometric model can be the parent of models with different material properties/loads/masses/analysis types.
At this moment RSAP have some options under detailed beam analysis, but it should be better if we can define longitudinal stiffeners in the web and check the stability of the web.
When you do the calculations for a new section type it would be useful to have the warping constant (Iw or H as I know it) reported in the list of data.
Looking at a similar post it may be that Robot doesn't calculate this? Strand 7 has the ability to calculate and it is very handy.
am inquiring about the possibility of applying fluctuating wind loads using spectral analysis? If that is not a viable option, are there any other ways to model fluctuating wind loads in the frequency domain using Autodesk Robot?
I am asking for designing of anchor reinforcement in concrete pedestals (EC3 + CEB). I have problems with designing columns base plates with big moments, when distance between anchor from edge is small - concrete resistance isn't enough(concrete cone failure) and we need reinforcement but we have'nt any possibility to calculate it in ARSA.
I am asking for new type of steel parametric member. It will be very useful for steel designers which use profiles with tapered web. Practically designer will provide structure geometry from steel joint to steel joint without recalculating coordinates of internal (external) flange thickness change and web thickness change.
The new type of steel member should look like this:
It could be used for example in such type of steel frames:
As you see, this part of structure requires 10 nodes (5 joints and additional 5). With new tapered members we will input only joint coordinates, the rest of nodes will be calculated internally in Robot.
Every frame optimization (by change of web or flanges properties) will not require to calculate coordinates of a lot of nodes located between joints, additionally we will have only 4 (5) members not 9 as in sample the picture.
I think it would be very useful to be able to design a baseplate where the column is eccentric to the base centreline. In my experience this happens quite often.
I think it would also be good to be able to have the bolts eccentric/assymetric.
Can you implement the reinforcement calculations for a "horizontal cut"? in core walls, tanks and pools
The cut position can be selected by user, and generate the drawings for the corner
with the posibility to add a inner chamfer?
