Problem with downloading opensees through cvs

Hi,

I tried to download opensees through cvs but it failed to connect to the server. Is this a problem with the server or I am doing something wrong?

Regards

Problem with zerolength elements in modal analysis

Hi, I have a simple one bay-one story frame with simply supported base conditions at both legs. Both legs are connected to the roof by equalDOF command in horizontal and vertical directions. The connectivity for the rotational degree of freedom is enforced by zeroLength elements with elastic uniaxia...

Here is a simple code to demonstrate the problem. It is a cantilever column with a monotonic imposed displacement at the free end. The problem is after analysis is done, "Elem1Sec1Deform.out" and "Elem1Sec2Deform.out" which are section deformations for sections 1 and 2 do not hav...

the number of integration points is 5. when I change dispBeamColumn to nonlinearBeamColumn, it records for all the sections but if it is dispBeamColumn, it just records for the sections 3, 4, and 5.

I tried former version of OpenSees released in 2005 and it records for all of the sections along the length of the element! But, in the latest OpenSees version, it just records for 3 out of 5 sections along the element. I need to compile OpenSees on Linux machine and 2005 version of OpenSees does no...

section recorders for dispBeamColumn

Hi Frank,

I have problem with recording section deformations for dispBeamColumn elements in my model. When I replace those with nonlinearbeamcolumn elements, recorders work fine.

having access to the element node which does not converge

There are some commands in OpenSees for example "nodeDisp $ctrlNode $ctrlDof" through which we have access to nodal displacements during analysis. Then we can use that in OpenSees code to have more control on the analysis. For some convergence problems, a message appears saying a specific ...

question about possibility of existing a command in OpenSees

Is it possible to know the element number which causes convergence problem during analysis? For example with "nodeDisp $ctrlNode $ctrlDof" we have access to nodal displacements during analysis and we can use it in OpenSees code to have more control on the analysis. For some convergence pro...

Problem with imposing displacement

Hi, I have a 2D model consisting of truss elements. I need to impose displacements on some of the nodes and run a static analysis. When I run the code, it gives error. But when I replace truss elements with 2D beam elements, it works. In the following, I copied the code for a simply supported truss ...
