I do reversed cyclic analysis using nonlinearBeamColumn and dsipBeamColumn，respectively.
But the result are very different.For example，the max force are larger when using dsipBeamColumn.
Why？
Thanks！

"forceAndDeformation" is general. you must specify the content just like as axialforce.

I think it is not necessary to focus on the factor just like 0.8 herein.

For example, error occurs when executing truss2.tcl. ===================================================== Error information: WARNING analysis Static - no Algorithm yet specified, NewtonRaphson default will be used WARNING analysis Static - no ConstraintHandler yet specified, PlainHandler default wi...

Thanks.

For example, after executing the run.tcl, three result files are generated, that is Element1_concrT.out, Element1_barB.out and section1.out. From line 3 of the file Element1_concrT.out, the strain is -0.000489952 at the location of y=11.625, and the corresponding curvature is 4.21464E-05(value1). Fr...

Recently I study the example of add new material. the file of ElasticPPcpp.dll is generated successfully, However, error occur when run the example1.tcl. the error is as follows: The instruction at "0x01ae937f" referenced memory at "0x00000000", The memory could not be "writ...

the file size of the OpenSees.exe after compiling by myself is 14.1MB, is larger than the download OpenSees.exe, why?
(The release of the source code and download OpenSees.exe is 2.3.0.)

Maybe there are other nodes in the nodes which belongs to the joint2D element

In the uniaxialMaterial Steel02, I know the cr1 and cr2 are the parameters that control the transition from elastic to plastic branches. And a1 – a4 are the parameters that define the isotropic hardening. But I want to know the specific meanings of these parameters, or the formula including these pa...

I am simulating beam-column jionts under reversed clylic loads. but I don't know how to determine the value of p1, p2, p3 and p4 of the shear panel for BeamColumnJoint? and also Positive/Negative envelope Strain, that is pEnvStnsp? I use the mcft theory, but the force-displacement results don't repr...
