Thank you for your response fmk. I will proceed with dispBeamColumns then.

Hello all, I am trying to track the vertical floor accelerations of a fiber element frame model. To do so, I must input a recorder at midspan of the beam members. I have read that you should not input a node at midspan when using force based beam-columns as it causes stress buildups at the node and ...

Hi all, The description for concrete06 states that it is used, " to represent concrete behavior in membrane elements". What is meant by membrane elements? Am I not allowed to use this material in beam-column elements? When I use this material, the behavior is similar to the other concrete ...

Thank you fmk. That was the problem.

I forgot to mention that the above lines are taken from the source code for the shear limit curve. ShearCurve.cpp

Hi, I have been working with the shear limit curve. When I execute the following lines in the checkElementState function, OpenSees crashes; if (defType == 1) // maximum chord rotations { Response *theRotations =0; // integer element returns in setResponse const char *r[1] = {"basicDeformations&...

Hi Vesna,

You currently updated the manner in which the OpenSees source code is distributed. I was wondering how I download the source code for past versions of OpenSees using the new SVN approach.

Thank you for checking that for me Vesna. I have implemented my material in the manner stated above. Everything compiles fine and the executable runs my previous examples. However, when I attempt to run an example using my new limit sate material, OpenSees crashes. I am a complete novice at coding i...

Hi all, I am attempting to implement a limit state material that will update its stiffness after a specified chord rotation (thetacap) is reached in the associated beam-column. I am using fiber sections to model my beam-columns. The updated stiffness of the limit state material will mimic that of a ...

Thank you Vesna.

Hi Vesna,

I am having difficulty locating Mohammad's contact info. Is there any chance you have it?

Thank you

Hi,

When I change the $defType from 2 to 1 in the CenterColShearSpring.tcl file of the limit state material debugged example Opensees crashes. I know that defType 1 is for maximum beam-column chord rotations. Why doesn't it work for this example?

Thanks
