Reinforcement Density in Continuous Foundations

[antipas]

Greetings, In my attached project, there are a lot of additional reinforcements, especially in the continuous foundations coming under the curtains. In the projects we have solved with the new regulation, there is a similar situation in the bottom of the columns, which are generally longer in length than the width in continuous foundations. Is this situation normal? Or my data entry etc. Is there a source problem? I would appreciate your help. Note: It is not final in the project.

The moments found by the program for the reinforcement calculation are as in the picture. The greatest moment in the span was formed at 1.4g+16q, but it was formed at the supports due to seismic forces. You can reduce these forces by increasing the curtains in the x and y directions. stirrups are also 12. either you will enlarge the section or you need to increase the curtains to reduce the forces. As you know, with the new regulation, earthquake forces have increased. It may have been because of this. the new regulations are a bit gattar. structure behavior needs to be given a little more thought.

You can reduce these forces by increasing the shears in the x and y directions. The stirrup is 12' First of all, you will either enlarge the section or you need to increase the curtains to reduce the forces. As you know, with the new regulation, earthquake forces have increased. It may be because of this. The new regulation is a bit gattar. You need to think a little more about the building behavior.

Thanks for your answer.
