Panel axial load results - Maps or panel cuts?

[skellyRSA2023]

Hi,

I have asked the question before however never really got a definitive answer. see the attached pdf. If you have a reinforced concrete wall and you want it to design it for a linear axial load say ULS, what is the better option, is it better to design based on the panel maps as shown in the attached pdf? if so there is a substantial difference in axial load kN/m around the panel which would depend on meshing etc. thus what would you design for, the maximum or is there a way of obtaining an average value? if so can these be found in tables rather than having to look at panels maps graphically all the time?

Or would it be better to use a panel cut along the bottom of the panel and work out a maximum load based on the length of panel? any opinion or advise on this would be appreciated.

I prefer to use panel cuts as you can have both max and min values of the chosen force across the cut.

to have the average ,pick the integral value and divide by the lenght of the cut.

You can set custom panels cuts of any lenght if you need to investigate a region where there is concentration of forces.

Rafael,

thanks for the reply. I think using the panel cuts will give you a more sensible results. If you have say a lateral wind load appLied to a panel which produces a concentrated stress on the bottom of the panel at the extreme edge, the panel maps will give you a maximum linear load at that point which in some instances can be very concentrated and excessive, compared to if you use the panel cut over the last say metre of the wall and design for a metre strip/length of wall which would be more reasonable. Is there any way of getting a tabulated linear loading for the panels? I.e. In table format in say kN/m other than going to reduced results for panels and dividing by the total length of the panel, as this would not take into concentrated stresses at the ends of the wall?

it would be good if autodesk had a webinar on interpretation of results for walls/panels especially as there is seems to be alot of ways of presenting the same results with slightly different out comes.
