Dear fmk, I am trying to model an eccentric 3D bridge (and compare the results with an experiment). I have a diagonal mass matrix with masses along local x-and y-directions and a rotational mass about the local z-axis. How can I model this rotational mass? Is it enough to assigned masses at deck lev...

I have a diagonal matrix with masses along local x-and y-directions and a rotational mass about the local z-axis. I am trying to model an eccentric bridge (and compare my results with the previous). I checked my model using eigenvalue analysis. The three natural frequencies of my numerical model tal...

A super mediocre question - how does the rotational mass work in OpenSees?

Hi,
Is it possible to get videos on workshop of OpenSees Days 2008? I particularly need the one on numerical modeling of bridge in OpenSees.

Dear all, I want to build a new material model into OpenSees 2.2.0 (downloaded a few older versions, managed to build versions 2.1.0 and 2.2.0 only). I created a new project with the .h and .cpp files (Windows application) but I don't understand how to link it to the header and library files as ment...

Hi,

While creating a new project, which option should I choose? I don't need to build a DLL right? So, is it okay to use the default application settings?

Hi, I read the " How to introduce a new material into OpenSees, by Michael H. Scott". But I did not understand how to add the new material model to OpenSees Tcl Builder. What did you do after changing/modifying the TclModelBuilderUniaxialCommand.cpp file? Sure, I modified a few lines as instructed. ...

Hi,

You can use the win32functions.cpp available in the OpenSees/trunk website, not the downloaded one from svn. Go through browse source code.

Hi, Thank you so much for helping me around. I have a few more questions. When you compiled the dll, did it give you any problem with the win32functions.cpp file? I got the following error. Error 2 error C2733: second C linkage of overloaded function 'ops_getstring' not allowed i:\2015\c plus plus p...

Hi, Where did you get those missing files? I copied and pasted the code(which I found in the Opensees/trunk/src) and created a header or a cpp file by myself as required. But I guess there's another way around it. I am using VisualStudio 2010. I used an older Developer/core to build the dll, which d...

Hi, Yes, I successfully created dll but failed to run it in OpenSees 64-bit. I'd prefer it if I can run it in the 64-bit, without resorting to 34-bit. As for the missing files, they aren't in the core directory. You mean to say, I could just use a different filepath and download from svn? I actually...

Dear All, I tried building a DLL for ElasticPPcpp as demonstrated in the example with the latest Developer in MS Visual Studio 2010. But I got two error messages: Error 2 error C2733: second C linkage of overloaded function 'ops_getstring' not allowed i:\2015\c plus plus practice\3_elasticppcpp with...
