Natural Period in BuildingTcl

Post by khalil Ahmad » Tue May 12, 2009 3:26 pm

Hi Silvia,

Can I introduce a spacific Natural Period( e.g. 0.8 sec) in BuildingTcl.tcl. 1.5. ? if yes, please send me the files' name and the way to change it.

Thanks

Sarwari

what's the scope?
you could force it with an elastic portal frame.

Hi Silvia,

Is it possible to perform eigenvalue analysis in BuildingTcl Viewer v1.9? In Analysis Model there are only TimeHistory, LoadControl and DisplacementHistory for the Analysis Type.

Thank you very much for your help.

if you want the periods only, they are given to you when each analysis is executed, after gravity (so you can define a gravity-analysis only). they are given on the dos screen.

still, great idea!

Hi Silvia,

Is there any way to see mode-shapes of 3-D structures? I need to check whether torsional mode is occurred or not.

Thanks a lot for your help.
