SAP2000 Nonlinear Beam and Column Modeling using Default Hinges (Video 7)

[@engrshafiq1]

I have seen many videos and read many books on this subject, but the way you explained in the most simplest way and in well comprehensive manner, no one cannot explain this manner, even the developers of SAP2000 can't do that. Kudos to your excellent efforts.👌❤

[@SerhanGuner]

Thank you for your interest and nice comments.

thank you very much professor Serhan for this powerful video

[@yaseminyldz2429]

How clear explanation is this ! Thank you very much sir.

[@salardelavarqashqai]

Hi, Mr Guner. i read your PHd thesis about shear modeling of concrete sructures. it was well done and helped me for better understanding of modelling. I am working OOP C++ nonlinear finite element. and your text helped me. God bless you.

[@SerhanGuner]

Thank you for your nice comments. I am glad you found our research useful.

[@zelihakuyumcu3959]

It is really useful study for us. Just I want to confirm something about assigning shear hinges. In video (21:51) , shear hinge relative distance is 0.267 It is stated that Relative distance for left end of the frame =d/ length of selected frame element Therefore relative distance (457/(3660/2))=0.2497) is 0.2497, but in the video it is given 0.267, I couldnt get this value? I just want to learn is there any problem or not?

[@SerhanGuner]

Zeliha: good question. What video is doing is to add half of the bearing (i.e., support plate) length to d, that causes slight deviation between your number and our number. see 14:14 that shows pages from ACI 318 for this. Base plate dimension is not specified in the video. In the absence of this information, your calculation is correct. Good luck with your studies.

Thank you!

Thank you for the video. I have a question, ¿ How did you get the distance on the with of the beam (CL-Cl of outer = 127 mm ). I have the same question for the distance on the height of the beam (CL-Cl of outer = 438 mm ).

[@pacanakylee.45]

same question

Thank you Sir for giving such an informative video.

Our pleasure.

Ayrıca ACI 318 standardında çelik kirişler için kesme noktası mesafesi verilmişmi? eğer orada yok ise hangi ştantarda bulabiliriz. ayrıca sizin kiriş örneğinde hem moment hinge hemde kesme hinge noktası tanımlarsak program her ikisinide analize sokarmı?

Hocam teşekkür ederim.

[@abaich90]

Thank you very much for such a great video Dr. Guner! I’m trying to model this beam in another software and I would like to verify the results using the experimental data you show in the video. Is it possible to find and use this data?

[@SerhanGuner]

Thanks for your interest. I believe what you are looking for is given in the video description as a download link.

[@abaich90]

@@SerhanGuner Thank you for your answer Dr Guner. Are you referring to the Vecchio and Shim paper? Figure 6 shows the load-deflection responses, but I was wondering if there might be some raw data available for these responses.

[@MuhammetBilalAyan]

Hi, Mr. Guner, may you share nonlineer analysis of Shear Wall?

[@SerhanGuner]

Thank you for the suggestion, Muhammet. I am currently working on a continuous beam modeling video, but I will consider a shear wall video when I have some free time. If you have specific wall design details (drawings, sketches, etc.), feel free to email me. You can find my email address from my university website.

Serhan bey selamlar, türk olduğunuzu düşünüyorum. türkçe biliyorsanız 2 katlı bir çelik çerçeve için sap 2000 içinde pushover analiz videosu çekebilirmisiniz? ayrıca pushover sadece yatay yükler için değil sanırım. düşey yükler içinde plastik dizayn yapabiliriz herhalde.... ayrıca video içinde plastik analiz sonucuna göre boyutlandırmanın nasıl yapılacağı hakkında bilgi verirseniz sevinirim.

[@michuutimes]

It is such a nice tutorial! Thank you for sharing, but can you please tell me how you got the 64mm from the bottom to the center of the M30 bar and also, what is the vertical space between the M30 and M25?

[@SerhanGuner]

Thanks for your interest. The question sheet given at the end of the video provides the details for this beam. More in-depth information, including the vertical spacing between rebar layers, can be obtained from the experimental testing paper: vectoranalysisgroup.com/journal_publications/jp49.pdf I hope these help!

hello every one. i am doing research on sequential Ground Motion Mainshock and After shock, the question is, is there any option in SAP2000 to define two ground motion in one time but in a gap of time for example 100s. that software do analysis firstly for main shock and after 100s do for after shock. plz help me. thanks in advance

[@cagrozsucu3961]

Hocam merhaba. Öncelikle video için teşekkürler. Autohinge tanımlarken, V Value From kısmında case/combo Dead olarak seçilmiş. Ama dead load'u herhangi bir yerde kullanmadınız.Bu kısmı açıklayabilir misiniz? Bir de pushover analiziyle ilgili bir sorum olacak. Pushover load case'i tanımlarken, Sap2000 bize üç seçenek sunuyor.(mode, accel, load). Sismik ananliz için hangisini seçmek gerekir? Pushover analizle ilgili bir video yayınlayabilir misiniz?

[@fratkaymak1271]

tabiyki "accel load" sececeksiniz. ayrıca benimde size bir sorum olacak müsaitseniz.:))

[@rafaelsalgado7562]

You are correct. The "V Value" when defining the automatic moment hinge should be from the load case with the maximum V. For the example given, that should've been the "Force" load case instead of the DEAD load case. The shear value, however, doesn't change the capacity of the moment hinge, it only changes (very slight) the response of the hinges in terms of deformation. You can get more details if you look at the FEMA 356 document from which these hinges are calculated from. For this problem, as shown in the video, the moment hinge does not fail, so choosing DEAD for the moment hinge definition does not change the results of the video. For the question about the pushover analysis, this video explains how to do a pushover analysis using force-controlled and displacement-controlled analysis, so you can use the same for a static-equivalent earthquake load condition. If you want to apply dynamic earthquake analyses (like a time-history analysis) then you would have to use an acceleration analysis. This process is a little bit more complex than illustrated in the video, though, and unfortunately, we don't have a tutorial about that yet.

Serhan Bey merhaba, çok güzel video olmuş. Ellerinize sağlık. Acaba basit bir sistem için P-M2-M3 mafsal tanımı, akma yüzeyleri ve moment-eğriliklerin tanımlanması hakkında da bir videonuz var mı ? Ya da çekme ihtimaliniz. Kolay gelsin.

[@SerhanGuner]

Thank you, Merve, for your interest. In this video, we focused on shear hinges which is more challenging than moment hinges. Your suggestion is also great. I will ask one of my students to record a short video when they do bi-axial moment interaction modeling. No promises though! This may be within 5-6 months! Keep the notification bell turned on to get notified.

[@hemilcivil3909]

Very nice sir...all concept clear....about user define hinges... Sir for cracking visuals effects which software u shown???

[@SerhanGuner]

You may try VecTor5. See our web site for more details: www.utoledo.edu/engineering/faculty/serhan-guner/ It is a free software and you can download and use it for your research.

[@amirkushma6636]

There is no FEMA 356 Auto Hinge option in my SAP2000. Can anyone help?

[@SerhanGuner]

You may be using a different version of SAP2000. There should be another option such as ASCE-41. Of course, each code is different and you should ensure you are using the one applicable to your case.

[@amirkushma6636]

@@SerhanGuner I am using SAP2000 V24. There is only ASCE option. Should I have to user define the hinge properties as per FEMA 356?

[@adityaballolli7031]

sir it was really very informative video.. thanks a lot.. but sir i have a small doubt, what is the formula to calculate monitored displacement value?? hope you are free to answer my question sir.. thank you :)

[@SerhanGuner]

The monitored displacement comes from SAP2000 results. You should not need any formula for it. Take a closer look at the video for the results where you will see the displacements. I hope it helps.

[@leonardoperez1673]

17.02 "And everything should be ok" There is a lot to explain in that window, come on

[@SerhanGuner]

Hi Leonardo, we used this wording because you are using automated hinges and there is nothing else to adjust. We also have another video which uses custom (i.e., user defined hinges) which may be what you are looking for. I hope this helps. Dr. Guner
