Re: ConfinedConcrete01-FRP wrapping

I have continued using this material. I have performed several pushover analyses. I found that if I change the fcp (unconfined cylindrical strength of concrete specimen.), the curve is the same. The material tester gives a different behaviour of the concrete. However, that's not represented in the c...

Re: Infill-RC Frame Interaction with element removal

Here is the corrected file that now reaches the end of the analysis. MOD1_Infills_2.zip The main source of error was due to the fact that, for this kind of element removal, the only system that works is the BandGeneral , because it is the only one that correctly resizes the system matrix after elem...

Re: Infill-RC Frame Interaction with element removal

Hi again, I tried to model the infills in this new model in which the RC elements are divided to be retrofitted.. The thing is that when I tried to mesh the faces, they are divided into squares due to the other elements divisions. I do not know what to do so that the faces can be divided into one to...

Re: Modelling infills in RC frame

Hi again, I have continued modelling the infills considering this procedure. The same error that appeared in the box model appears in this model... I have used an interaction between infills and superstructure and apply equalDOF. Then i did not divided the infills trusses... I used 1 as uniform numb...

Re: Infill-RC Frame Interaction with element removal

Hello, I have updated the file and changed the mesh of the structure. However there is an error appearing. I do not know what might be wrong. Regards. SectionForceDeformation *getSectionForceDeformation(int tag) - none found with tag: 0 ID::resize() - size specified 0 <= 0 Increment: 13 - Iterations...

ConfinedConcrete01-FRP wrapping

Hi! I'm trying to use the ConfinedConcrete01 uniaxial material to simulate the FRP wrapping of columns. I have created the material and added the values in kN-m. When I try to perform the material test, the following error appears: Error: Traceback (most recent call last): File "C:/Program Files/STK...

Re: Transverse reinforcements

Hi. It depends on how you want to model your structural elements. There is an option that is presented in the STKO tutorials. In the physical properties, add a new property following: section, rectangularfibersection. You can find there how to add the stirrups' characteristics. Hope it helped you. R...

Modal analysis error

Hi! I am trying to carry out a modal analysis of a RC frame structure. I have added the masses in the edges (columns and beams) as one of the examples available at youtube (same values). I copied the modal analysis code of the example and I added some recorders to obtain the eigen values for the deg...

Re: Infill-RC Frame Interaction with element removal

Dear all, I have tried to follow the webminar to model the infills in a RC frame structure. However, the following error appears which I do not understand. I think that it is related to this topic openned a while ago. I think that it has do to with the -j that appears in the code. It also appears in...

Re: soil structure interaction

Hi again! I did that before posting and didnt work. I did it again and finally it is solved. The model seems to be working. However, the analysis stops in the 50th step... not reaching convergence...I have changed all of the parameters of the pushover analysis but no different results are obtained. ...
