Ground Safety Negative

[serdagi]

Hello, because the file size is large, I added it with wetransfer. I'm getting a "Ground Safety Negative" error in my project. No matter what I did, I couldn't fix it. the ampatage limits are already at their maximum due to the adjacent buildings. How can I overcome this problem? I wish everyone good work.

Hello, You made a unit error in data entry. Check again from the ground report and enter the soil bearing capacity and bearing coefficient values. The values you enter must be tf/m2. With TBDY 2018, the concept of "Soil bearing capacity" came instead of "Soil safety stress". Make sure that the bearing capacity information is entered from the ground report.

Thank you Yasin for your reply. Frankly, it is an old project, but it has not been implemented yet. We wanted to revise and try according to the new regulation. While the soil safety stress was found, the soil bearing capacity was found and divided into safety coefficients. The formulas in the new regulations are different, but we used the found carrying capacity.

THE NUMBER OF CONJUNCTIONS AND COLUMNS IS HIGH BUT I CANNOT FIND A SOLUTION

Hello

https://we.tl/t-tBwDnfWGKz THE NUMBER OF CONNECTED ORDER AND COLUMNS IS HIGH BUT I CANNOT FIND A SOLUTION

Why are you solving according to TDY2007? Unver ÖZCAN

 

[orhan günay]

I'm doing it in addition to the old project.

 

[orhan günay]

There are buildings on both sides, so I will solve it with dilatation in this way as a project modification.

 

[orhan günay]

Should I convert the old ground coefficients according to the new system?

[ quote="orhan gunay":1ea4gihk"]Do you need to convert the old ground coefficients according to the new system[/quote] Even if you add to the old project, you should make a solution according to TBDY2008 as it is a new project. For soil tension: You cannot convert the old soil safety coefficients to the new bearing capacity ground values A new geotechnical soil report is required Ünver ÖZCAN

should we convert the old ground coefficients according to the new system

In the new regulation, the factor of safety in the soil bearing capacity has been reduced, so in a sense we will now work with higher ground safety stresses, but the control is 1.4G+ It will be done with 1.6Q, there is also no 50% increase in case of earthquakes.So they increased it on the one hand and decreased it on the other hand, all should be evaluated together.
