Has anyone worked with EACD-3D96 or EACD-3D2008(a computer program for three-dimensional earthquake analysis of concrete dams)?

 I got the source FORTRAN code from NISEE, The Earthquake Engineering Online Archive, but i won't work there are some compile errors that i couldn't fix, could anyone help me on this ?

Hi

is damping of wood, function of frequency?

I mean the wood damping is frequency dependent or no?

if yes, any body can help me to find a reference for numerical data of wood damping as a function of frequency?

 thanks alot 

Hi,

In order to model a jacket supported by four piles I need to model the interaction between soil and piles in ANSYS ASAS-NL. As I want to make a trasient analysis I use ASAS-NL which unfortunately do not interact with SPLINTER. The jacket structure is modelled by 3D beam elements. Can someone tell me how I model the soil pile interaction? Is it possible to make use of P-Y and T-Z curves in ASAS-NL?

Greetings, I have used I-Deas previously, and purchased ADINA 900 Nodes to attempt a similar project.  However, I have not been able to find an answer to a simple question.  Namely, I have created a parametric equation for a parabolic shell, and I would like to see it appear in the graphic window. I will post the file in a response line.

Hi,



I am new to abaqus scripting. I need some help with accessing the odb for history output.



I have a list of odbs and i need to take the displacement and contact stresses information at the end of the step.



The syntax i tried was



import odbAccess





fileName = 'static_open_c1.odb'

stepName = 'Load'

historyRegionName = 'Node HS-1.701'

historyOutputName = 'U2'



session.odbs[fileName].steps[stepName].historyRegions[historyRegionName]

I'm having problem with the following problem. The encircled portion of the figure is giving me trouble. I am getting confused on how to correlate it with reference frame oxyz. please help.

what is the significance of distance r for calculating angular velocity of the reference axis oxyz?

 
I need to find out the components of the absolute acceleration of O along ox,oy& oz.

I'm trying to investigate the effect of multiple support excitation (spatially varying ground motion) on seismic response of an arch dam using ADINA, so i need to apply different acceleration (and velocity and displacement) time histories on every node on structure-foundation interface.

Hi all,

I've to model a gearbox in the transitory (acceleration) and in the
stationary (constant speed) running: i'm not sure abut the kind of step
to use.

I'm gonna find contact pressure and stress in both case.



What about using static step for both?
