Dear Victor, I agree with you. Let's be honest I have too much ambition for a general FEA software which is effective for the scope it have been design for (and costless). There's no bugs on MECWAY. We can't compare specialized steel frame struct…
-
Dear Andréa, according to the picture, I will say beam analysis. shell will cost a lot of ressources and there's no reason to go this way. There is some specific connections and gusset that will be step out of the analysis, if it's ok for you go for…

Dear Victor, as you've asked before I have made a model without any MPC and no local masses and only merged nodes full embeded columns fixation on MECWAY and ROBOT. Here's the results: bending moment on the top of the columns (the same as before): …
-
Hello Andrea, yes I have taken a ductility class factor q = 1.5 for both ROBOT and MECWAY by divide by q the accelerations of the elastic spectra. I think that doing elastic spectrum test shoud induce considerably worst results. BR Sofien

Hello Victor, I'm not sure that I have understand. You mean suppress all these loadcases, I am interested by the loadcase n°18. Or are you asking me to suppress all MPC? For torsionnal masses I am speaking about modal analysis, ROBOT can suppress/…

Thanks disla, I've tried it yesterday anyway I don't works. According to the manual, it doesn't work because of several constraint equations on my model. Maybe it could be fixed for the next version of MECWAY. BR Sofien

Thanks a lot Mishal, Commercial code have been developed for more than 30 years by pro devs for some of them... There are widely used by people who had a full trust of the efficiency of their software which it's cost a lot to buy and upgrade every …
-
Thanks disla, according to my previous message it don't works, I don't know how to output modal analysis results in this conditions. If you have a trick, let me know. Regards. Sofien
-
Thanks Disla, See in attachements ROBOT modal analysis results and options. Same modes number (50) as you can see there's only 40.42% of the Z mass fraction that have been taken into consideration on ROBOT model but without the MECWAY dynamic res…

thanks a lot Victor,

This is for beam analysis of course.
-
I Andrea, could you send us more accurate inputs a hand sketch with some dimensions between shear forces and boundaries? How much are the vertical shear forces? Regarding the picture, it look like a bending excessive failure. Maybe local buckling d…
-
Agree with disla there's something ugly on my model here some other example: I have no axial forces and bending moment (strong axis) on the column n°19 and 23 which is impossible here below some table extract with dynamic analysis case 1 vs static …
-
Thanks Victor, in that case I Will use beam forces at the edges near external bounding conditions. All this issues with dynamic reponse 3d analyses should be solved for internal solver on the next versions of Mecway (using beam releases, extract rea…
-
Hi every one, I've finally launched my first dynamic response analysis with a seismic spectra (T(s) vs Acceleration (ms-²)). I have some trouble with beam release which it's not allowed with this kind of analysis but why is it not possible (maybe g…
-
Thanks a lot Victor, for the future version of the software maybe another method for the beam release for the beams which are not compliant with the global axes for these one we can't use constraint equations. Regards
-
Thanks you Victor, it worked perfectly. One last question, the beam releases can be managed by two methods : -using hinges with the flexible joint on beams methods -using contraints equation only on ux/uy/uz which means that the other dof are free t…
-
Thanks Victor, in order to be sure I send the model once again with constraint equation and hinges. With or without hinges the issue is the same with this error message from MW when I run the case 1: 00:00 Start 18:33:39 . 00:03 Allocating matrix 00…
-
Another question arise, how to deals with multiple nodes to constraint? For exemple 4 elements can share 4 nodes at the same position (x,y,z). How to deals with constraint equation in that case? We have to choose a master node to link with the 3 oth…

-
Hello, Victor, I've performed the connection between nodes with constraint equation this way for exemple on the liml file(nodes 61 which is the master and 82 the slave): …
-
Thank you Victor
-
Sorry, for this post, i've read the Mecway user guide for sure it can be done with the dynamic response analysis. Regards
-
@Victor, yes you guess it right, I actually use scripting (VBA6, and Python + xl librairies) in order to automate pre processing (geometries, loading, loadcases) it's unaccurate for loading and it don't take into account hinges releases (i'm not a g…
-
Thank you Victor, in my model there's a lot of connections between beams. Is there a way to spot nodes which shares the same position? How do you manage constraint equation with these nodes? Regards
-
thanks a lot here's the model (as asked by Victor)
-
Thanks a lot disla.

Hi everyone, I want to perform an spectrum analysis according to the EuroCode with MecWay/CCX. I can't use simplified method for this case. Is it possible to perform response spectrum analysis combined with modal analysis with SRSS combination? Rega…
-
Thank you Victor.

SORRY... Second try some words were missing. Hi every one I am struggeling with the same kind of problems. I mean multiple loadcases studies with Steel frames according to EuroCode standards. I had made a lot of improvements to create liml xml …
