hello, i am quite new to AutoCad and im currently working on AutoCad 2014. The polyline is not moving in any direction other than X. I checked the snaps and tried to fix the drawing plane to ....
In order to create envelope diagrams, I'm about to create separate load cases for each span of a 30-span bridge and both symmetric and asymmetric loads. Is there a way to edit the load cases i excel,...
I've modeled a two story building with steel columns, beams, concrete floors and cross bracing. Static analyses, with and without static loads, run perfectly well. However, when I attempt a modal ana...
During non-linear analysis on a structure with planar rigid supports with released uplift, I get an error displaying "execution problem no 902". What might cause this? BMan
Hi. I'm doing a non-linear analysis on a simple model with static loads from a seismic analysis (separate file) to determine necessary moment in my foundation slab. However, whenever I get n...
Is there a way to display the buckling shapes of a structure? In my case a plane truss with no external bracing.
Referring to EC8-4.3.3.2.2(1) and the parameter lambda (correction factor related to number of levels), where can I find the value used by Robot for seismic analysis? It seems to be omitted from the ...
I'm designing a steel roof structure using Robot 2012 x64 on Win7. When designing steel connections (column base) the program seems to confuse tensile and compressive forces. I've attatched screen ca...
I have a model with several load cases and manual combinations. Results from load cases are as expected, but results from my combinations are completely missing. My reactions table say N/A for all co...
Hi. I've got this steel structure with wind braces and simply supported column bases all around. This configuration mostly gives the expected distribution of reaction forces: with even verti...
