Current building performance analysis

[iboztrk35]

Good work everyone, I need to do a performance analysis of an existing building for my dissertation. I have an architectural and static project in hand. After drawing the static project in idecad, I make the reinforcement arrangements, but some problems arose; 1- After entering the stirrups in the columns, the reinforcement gave insufficient (As-) errors in all columns 2- The reinforcements were also insufficient in the floors, there are also the cross reinforcements given in the project in the console floors, I think it is called tearing reinforcement, I am not sure how I can enter them in accordance with the project and as in the project If I do not enter diagonally and add additionally in x and y directions, will it replace the same diagonal reinforcements? 3- Does the insufficient equipment in the performance analysis affect the results of the performance analysis? After all, I enter the accessories as they are in the project. 4- We can determine the distance between the bottom of the stirrups in the program, but can I change the spacing of the stirrups at the upper end of the column? For example, in the project I have, the upper tightening zone is 64 cm, the middle zone is 51 cm, and the program determines them as 60 cm and 55 cm. Thank you for your answers in advance.

Good work everyone, I need to do a performance analysis of an existing building for my thesis. I have an architectural and static project in hand. After drawing the static project in idecad, I am making the reinforcement arrangements, but some problems arose; 1- Columns After entering the stirrups, insufficient reinforcement (As-) errors were given in all columns

Reinforcement shortage message is for new building design. You are entering the existing reinforcements of the current project, there may be a missing Ace message, or there may even be other negativities.

2- In the same way, the reinforcements were found insufficient in the slabs, and there are diagonal reinforcements given in the project in cantilever slabs. quote] Floors are not one of the elements to be evaluated in linear performance analysis. ir. Therefore, defining the floor reinforcements does not affect the performance analysis. (You can define the cross reinforcement by stretching a reinforced concrete calculation axis at that angle.)

3- Does insufficient reinforcement in the performance analysis affect the results of the performance analysis? As a result, I enter the reinforcements as they are in the project.

Since the amount of reinforcement will affect the capacity of the elements, it certainly affects the performance analysis, but you enter the reinforcement of the existing building, if there is a lack of reinforcement, it is there because the existing building Performance analysis will be formed accordingly.

4- We can determine the distance between the bottom of the stirrups in the program, but can I change the spacing of the stirrups at the top of the column? For example, in the project I have, the upper tightening zone is 64 cm, the middle zone is 51 cm, and the program determines them as 60 cm and 55 cm. Thank you in advance for your answers.

The important thing is to give the stirrup capacity of the existing building. Stirrup information is in the form of middle-hugging-joint zone. Enter the spacing and diameter value that will be effective on the stirrup capacity to the program in the column reinforced concrete. For example, you will give fi8/51/64/64 according to the values you have written for the column stirrup. Apart from that, it is seen that there is no compaction in the existing columns. For this, you need to remove the "There is stirrup tightening" option in the column settings, in the performance tab.

Thank you for your answer it was very helpful. I have one more question, in beams, two beams are continuous (K201>>K202), but K201 is attached to another beam at the left end. In my current project, I have given the assembly and flatness of K201 and K202 beams differently. How can I enter it as in the project in both beams?

Thank you for your answer, it was very helpful. I have one more question for beams, two beams are continuous (K201>>K202) but K201 is attached to another beam at the left end. And in idecad, although I entered it differently, it uses the reinforcements of K202 in beam expansion, how can I enter it in both beams as in the project?

Look at the beam reinforced concrete dialog. i mark it as not console. After the analysis, you can arrange the reinforcement.

I have one more question. It's not important for performance analysis, but instead of leaving gaps for stairs, I thought I'd throw a floor. However, in the plan, the additions I made to the floors on the sides of the stairs are not visible after I have removed the stair slab, but are visible in the slab reinforced concrete window in the formwork plan. How can I solve this problem?

I have one more question. It's not important for performance analysis, but I thought I should put tiles instead of leaving spaces instead of stairs. However, the additions I made to the floors on the sides of the stairs in the plan are not visible after I have thrown the stair slab, but the slab is visible in the reinforced concrete window. How can I solve this problem?

If you add your project and show what you've done, we can better understand your question and we can help.

Thank you for all the questions I asked above. I have a final question, can we get the capacity curve of our building after the idecadten performance analysis, does the program not give it automatically? Or do we have to create it ourselves by taking the base shear forces and displacements?

I have solved all the questions I asked above, thank you. I have one last question, can we get the capacity curve of our building after the performance analysis from idecadten, can we not automatically give it to the program? Or do we have to create it ourselves by taking the base shear forces and displacements?[/ quote]
