Lever static

Hi Jon, it´s agine me :)

first at all thanks a lot to your help last time, but i found another way to solve my problem ( i had use deformation and then repare the lost connection betwen the lines whit one Toll in VB which i wrote (not so elegant but works)) but that´s not what i´m into now.

we (me and my civil enginieer) found this picture in net and wething we could use the system for our structure, we had try it in a model and it works

the question are the forces, if the structure is symmetric it´s no problem there, but if we try to make it littelby asymmetrical are the forces not everywhere the same, it´s possible to use some of your tools to check the forces or deformations ( "problem" is the force translation schould not work an all directions ) see te pic

every beam works as lever, do you see some possibility to make structural analysis for this ? somtrhing what show as which deformation( idea is to change the position of the upper points=the support lines (lenght, angle etc) change too) of the structure is possible?

thanks a lot to all your help

cheers Mike

Hi Mike,

Looks really cool, glad you found a way to model the frame.

What structural analysis software does your engineer use? I've just uploaded the first alpha build of Egret which can conduct Structural Analysis. I'm still working on extracting various results etc, but the attached model can report deformation (I made various assumptions about restraint, material, member size and loading).

You'll see the Oasys GSA components are disabled, I was using it to cross check my results.

Hope it helps,

Jon

wow thanks a lot, it looks great, i have to send the data to my enginieer to see what he says to it, but it seems like a great work from you really great :). did you update the oasys plugin ?, during opening grasshopper says many errors by the gsa components.

but thanks a lot really great work

cheers Mike

Hi Mike, Are you sure the error is the GSA plugin? From your license file, not sure if you installed egret yet.... http://www.geometrygym.com/downloads

yes i have egret now, it works great, i still have gsa 0.9.21 i thing you use 0.9.24, so i will update it,

my engineer use RStab here is the link to it http://www.dlubal.de/RSTAB-7xx.aspx

thanks agine for your help

Mike
