Hello friends, there is one floor addition project. When I made a performance analysis, I could not meet the life safety requirement. I would be very happy if you could review my project and share the places I missed. Thank you all for the good work in advance.

Hi, No reinforcement corrosion and insufficient clamping length in the 1st curtain settings yield stress multiplier is given as 0.4. You gave 1 in the columns, check these values. 2. There is dilatation in the basement floor. Consider both dilatations as separate projects in the performance analysis evaluation. 3. By ticking the option 7A.3 apply axial upper limit clause in shear and column adjustment You can perform performance analysis 4. Beam and curtain reinforcements do not appear to be fixed, however, you must enter the reinforcements of the existing structure 5. Raft foundation finite element width 5 meters given. 25 cm is the default value. After these materials are applied, your structure comes out before collapse due to beam bending moments.
 
In addition, I would like to say the following. Review the loads of your structure. Live loads seem to be 0.35 almost everywhere, how real is that? In addition, on the top floor you added, you took 0.40 as the floor constant load, for what reason did you buy it, with what will you cover the attic? Do you need live loads in the attic? Do you need live load on the beams? You have used the comprehensive knowledge level as the knowledge level. In order to use a comprehensive level of knowledge, you must have reached almost all of the detailed information about the building and ensured that all of it was done on site.
 
My teacher NYILMAZ, since we have a building and static project made under construction supervision, I used a comprehensive knowledge level. The reason why I chose the live load is 0.35 to stay on the safe side. I took the dead load of 0.4 due to the wooden roof on the top floor. That's why I added them. I searched for the reinforcement corrosion and insufficient clamping length yield stress factor, but I couldn't find it. In the static project, dilatation appears on a single foundation, so I did it that way, and I need to analyze the separation separately. Finally, if it comes out before collapse, I need to add a reinforcement curtain.
 
If you are going to do a performance analysis, I don't know how accurate it is to increase the loads in order to stay on the safe side. The main thing here is to model the building as close to reality as possible. That's why I suggest you rethink the load issue. In this context, having a project or having a building subject to inspection does not require you to have a "comprehensive" level of knowledge. You should gather information from the structure with adequate inspection. You must perform the beam and column reinforcements with destructive stripping and x-ray equipment. That's how you can tell if your project is being followed. In particular, it is not possible to see stirrups, stirrup hooks and corrosion conditions without stripping the reinforcement. You can see where and which element will be strengthened from the column, shear and beam performance analysis results. Here, under each element, it is written which type of damage it is exposed to. Based on this, you should decide whether you will strengthen that element or add an additional reinforcement curtain that will reduce the loads on that element. If you examine the TDY section 7.7 and the table in which it is found in the reports, it will guide you.
 
Even if the project solved with C25 performs a performance analysis in its own class, why does it want reinforcement for many curtains in the basement? Sent from my SM-G925F using Tapatalk
