Performance Analysis

[huseyinakkus56]

Hello.. After the Linear Performance Analysis in the attached project, how can I find out which section of the GP03 Group curtain in the Advanced Damage Zone is insufficient? Also is there a way I can recover without reducing the thickness?

Hello, My suggestion: If your building was built last year and it complies with the attached communiqué, you should perform the performance analysis of your building according to IdeCAD 8.62. Entering the current status of the reinforcements in the columns and beams in the building (DS) and fixing them. Then do performance analysis. Unver ÖZCAN

No, sir, the building has not been built yet. The municipality asks us to ensure performance for new projects as well.

There is something strange here, performance analysis is not required for new projects. Why does he want it?

Unver, a crazy person throws a stone into the well and then forty smart people can't get it out. The problem is that control engineers do the job with hearsay information.

One of the proofs that we live in a really fun country (!) Ask what article of the regulation it wants this. Also indicate that you do not want this project as a double project budget.

Hello there; Since the regulation says DGT design KH performance target for the new buildings to be built and it gives a performance report in addition to zero calculation in some programs, it is normal to be perceived as such * In your project, you cannot accept a curtain wall system for the Y direction in accordance with the article 4.5.3.3 of the regulation, that is, R=8 in the Y direction of the building. D=3 should be chosen and the solution should be made. ** I don't think you should give much credit to shear wall reinforcements in zero calculation, shear horizontal reinforcements calculated as a result of DGT are generally insufficient in performance evaluation. I would say use a minimum of Ø12/20 diameter and spacing. *** The reinforcement arrangement of the group curtain parts that do not meet the curtain requirement can be made like a column, maybe your problem may be caused by this. Best regards.

Thank you, but how did we make the curtain reinforcements like columns?

Hello there; In group curtains, there are two ways to equip parts that do not meet the curtain requirement, such as a column/header region: 1- You can enter these parts as columns. This method is debatable... 2- Although it doesn't work very well, enter it as a curtain and edit the curtain title area as user-defined as in the attached picture. I said why it is not working properly; because even if you select the entire head area, the program still calculates a hull reinforcement and is prepared in that way in the drawings. You will need to do some editing. We expect improvements in future updates regarding this issue. Best regards.

I understand, thank you very much.

According to clause (c) of the 17.July.2019 Regulation, the project must either be recalculated according to the new regulation or a performance analysis must be made. The provisions of the regulation on the date of obtaining the license are valid only for the constructions that have started.

A new project is currently underway, according to the new regulation, it was enough to do DGT, and a performance calculation of SGDT with linear calculation method was requested.

Exactly.

Erhan Bey Hello, Ünver Bey and after the message written in the reply that the building was not built; I perceived that the building was licensed but not started, and I wrote my answer based on this.

Friends, Some administrations want to ensure themselves in this regard. The reason for this is that in case of any project incompatibility or conflict during the construction of the building, the building is checked according to section 15 when going to the court or expert. There has been a lot of conflict like this in the past. Although it is stated in the regulation that the design made according to the 4th chapter provides DD2-DGT-KH performance, checking with SGDT ensures to be prepared for such situations. Under normal circumstances, the design made according to section 4 should meet section 15 of the SGDT. If it does not, interventions to make it possible must be done in advance (I am not saying this according to any regulation article, I am saying it on the basis of the general regulation principle). Of course, while performing performance analysis according to SGDT, it is necessary to check that the structure meets the linear performance analysis criteria. This control is done by Idecad. These should not be overlooked. If it does not meet the linear analysis criteria, bringing it to a state makes analysis and control easier. Otherwise, it is necessary to go for non-linear performance analysis, which prolongs the work. If your curtain horizontals do not provide SGDT, I suggest you intervene in a way that will.

Thanks for your comment.

Greetings, Mr. Suat. 1 <BYS<5 (DTS 1a, 2a ise 3<BYS<5) yapıları sadece doğrusal analiz ile tasarlayabilecekken bunu istediklerinde doğrusal olmayan analiz gerekecek ve buna mühendisin müdahale edip doğrusal analize çevirmesi de imkansız.

Bu keyfiliğe kesinlikle karşıyım.

Hello Mr. Erhan, You misunderstood my message. Let me try to explain more clearly in case there are other misunderstandings. The DTS 1a, 2a you mentioned are important structures. It is not possible to change the DTS of a building whose location and purpose of use are certain, and you cannot change the height of the building. What is mentioned here is the performance analysis of a newly designed project that is still in the project phase. The issue I am trying to explain is that a performance analysis is requested for a structure that has not yet been built on a question asked before in this forum. In this case, performing a performance analysis on the structure is for the administration to ensure itself. This is not too wrong. For this reason, it is necessary to perform additional performance analysis on your buildings that you design as new constructions. In performance analysis, it is to design your structures in a way that will meet the linear performance analysis conditions (conditions in article 15.5.3.1). This means column capacities, beam capacities, rotations etc. that is, you design your column beam and curtain wall systems accordingly, which affects the rigidity and behavior of the building. Of course, if your structure does not meet the BYS class, which is the first item of the criteria listed in 15.5.3.1, it means you are already building a high (higher according to this item) structure and you have to make a non-linear performance analysis. I hope I was able to explain.
