Did you use the tips that I mentioned?

Hi IsmBaha, you can use many pined support that all of them act together as fixed. use finite element.
But now I have a frame model with fixed support and zero length element that work without and error if you want I can send you.

I modeled a frame with this bond-sp and zero length element and it run without any problem if I put pined support as I change the support to fixed it dosenot run. I think this element has problem with fixed support.

Any reply mr fmk?

any answer?please

Hi
what dose ''Bar Fail'' means during the analysis when we use reinforcing steel material in RC modeling ???
dose it means buckling of longitudinal bars?????

Hi fmk
how could I found Sy in USA units?

Hi fmk Can we use R=0.3 in uniaxialMaterial Bond_SP01 this is that I used uniaxialMaterial Bond_SP01 $tag2 $Fy 0.056 $Fu 2.24 0.5 0.3 but Pinching factor for the cyclic slip vs. bar response is between0.5~1.0 but I get good answer with R=0.3 what about Sy? what is alpha for creating Sy?why we must g...

Thanks Mr.fmk for your suggestion. I make a small model with the ksi and inch units. but as I change the variables for ((uniaxialMaterial Bond_SP01)) such as Sy , Su and R the result dose not change as I expected so the hysteresis behavior dose not differ as I expected. for example pinching never ch...

sorry I make a mistake this error was for bond slip material this is my material for zerolength section element that make this error uniaxialMaterial Bond_SP01 400 50000 0.07 67000 1.7 0.5 0.5 but when I change 50000 to 72 and 67000 to 97 the warning disappear. what is that error?and please help me ...

Hi my model is RC frame with fiber section I use ReinforcingSteel material for steel my units are SI units but when i run my model the following message appear: warning:for the strain-penetration model: input value in ksi and in but my model work correctly what is that error?and please help me if it...

I have found the answer Thanks fmk I correct the section
I reduce the fiber in the beam section and the problem disappear

Hi,
I have RC frame with two bay and one story with Gravity loading and cycling load.

I would like to observe bar slip in Beam at joints. which material and element is suitable?
my model is fiber section
thanks
