FB beam column with NDFiber Section

Hi,

I am trying to use an NDFiber section to couple the torsional behavior of column with the PMM interaction. My question is if the current force based Beam Column element include torsional calculations or does it need to be modified?

Thanks

User Code and Parallel Processing

Hey all,

I am pretty sure I know the answer to this, but is there a way to use user written code with parallel processing on the NEEShub? If not, what might be some of the other options? Is this something one would use cloud computing for?

Thanks

Re: Instantiating A Class

Hey Guys, I figured out why it was saying I was trying to instantiate a abstract class. The issue was in the getType. I posted the correct way to meet the pure virtual of the NDMaterial below.

const char* getType (void) const;

Hope this can help someone.

Re: We are collecting OPENSEES User-Requirements Data

Hi,

It would be very useful to be able to define boundary conditions not along the global coordinate system. The ability to define fixity for along an incline or at an angle to the GCS would be very beneficial.

Thanks

Modelling Curved Bridge Boundary Conditions

Hey all, I am working on modeling a full scale curved bridge in OpenSees. I am trying to model the abutment boundary condition as pinned radially (transverse) and free tangentially (longitudinal). However, as far as I can tell, OpenSees only allows the user to fix the boundary conditions in the glob...

Modelling an Unbonded Prestessed Tendon

Hello all, I am doing some dynamic modelling and I am trying to figure out how I can model an unbonded prestressed tendon used to apply an axial load. I have tried just using an axial load, but it fails to account for the increase in axial force due to deflection of the column during dynamic analysi...
