<t>Hi, <br/> <br/> We will obviously need to see the model, in order to be able to comment on the behaviour you have observed. <br/> <br/> You may also perhaps explore the possibility of adding a 'truss' element defined between two nodes that are 250 mm below the beam nodes, introducing then rigid l...

Hi,

Try using 'truss' elements coupled with 'link' elements that transmit tension forces only.

Yes, of course, you will need to calibrate the elastic element properties in order to render them "compatible" with the link elements.

In alternative, you may also consider using plastic-hinge specialised software, such as Ruaumoko, Drain, Idarc, etc.

<t>Dear Maxime,<br/> <br/> We realise that this response comes with a very long delay and that you may have solved the matter by yourself. <br/> <br/> In any case, and also for the benefit of others who may be interested in the issue, we note that the behaviour that you observed (no apparent influen...

<t>Dear PhungNgocDung,<br/> <br/> We are not quite sure we understand the difficulties you seem to be experiencing, but we will give it a go, in any case, with an example:<br/> - define nodes A(0,0,0) and B(0,0,3)<br/> - define an elastic element going from node A to B<br/> - define node AA(0,0,0)<b...

<t>This message means that the Lanczos algorithm, which currently serves as the eigenvalue engine of SesimoStruct, could not calculate all or some of the vibration modes of the structure. <br/> <br/> This behaviour may be observed in either (i) models with assemblage errors (e.g. unconnected nodes/e...

<t>When subjected to earthquake action at its base, structures obviously do feature rigid body motion, in addition to relative deformation. <br/> <br/> Typically, such rigid body motion is of no interest for engineering applications, hence its plotting is redundant. <br/> <br/> In order to disable s...

<t>We are not sure we understand exactly what you mean by "it is not working".<br/> <br/> In any case, we can confirm that colouring of elements where a Performance Criteria is reached is working (Post-Processor -> Deformed Shape Viewer -> Performance Criteria Display).<br/> <br/> The only current c...

<t>Glad to hear the analysis now works. <br/> <br/> We actually believe that loading the program's default settings has made all the difference (you had previously tried changing the tensile capacity to zero, and that did not solve your problems), and thus recommend it to all users. <br/> <br/> The ...
