dilated solution

[aksualigurbuz]

take it easy. I have a project in hand and I left two dilatation joints in the project. I basically planned the raft and solved the system. Then (assume there are blocks a, b, c) I took out blocks b and c and solved only block a. But in this case, the tipping calculation He made an error. Well, there is no error in the dilatation solution, but why did it give an error when I solved it alone. And also the internal forces were different. I wonder if I misunderstood something. Isn't the purpose of leaving dilatation to solve each one separately. This is the case, the solution alone is the same as the other solution. Doesn't it need to come out of all forces and other situations. My second question is: according to article 3.6.1.2 of the earthquake regulation, there is a rule that total A g / total Ap will be equal to 0.002. However, that situation does not save me. My choice of R is appropriate in the system, but it does not save the areas. .can we skip this situation or is there a solution. My third and final question: the fret aces (alpha s) come out in the 0.86 state. In this case, do I need to soften the frets a bit? So, is it better to keep all the forces at 0.75 level, not on the walls, and transfer the rest to the columns. Because if alpha s comes out at 0.90, the columns get very little shear. What can you say as a comment to this situation. Could you pay attention to this situation in the projects you have done? take it easy, good work...

take it easy. I have a project in hand and I left two dilatation joints in the project. I basically planned the raft and solved the system. Then (assume it's blocks a, b, c) take out blocks b and c I only solved a block. However, in this case, it caused a tipping calculation error. So, there is no error in the solution with dilatation, but why did it give an error when the solution alone

If dilatation is going to be applied separately in the foundations of buildings, then it would be appropriate to design each dilatation as separate projects.

and also extracted the internal forces differently.I wonder if I misunderstand something.Isn't the purpose of leaving dilatation to solve each one separately.situation So, shouldn't the stand-alone solution be the same as the other solution? All forces and other situations

If you add a project where this situation occurs We examine the situation.

I have a second question: according to article 3.6.1.2 of the earthquake regulation, there is a rule that total A g / total Ap would be greater than 0.002. However, that situation does not save me. My choice of R is appropriate in the system, but it does not save the areas. Can we skip this situation? or is there a solution.

TDY 3.6.1.2 Equation. There is no rule that says it will be provided in 3.14 projects. If these conditions are met, the regulation allows you to reduce the wall thickness and reduce the total vertical and horizontal reinforcement ratio of the wall. (Reinforcement ratio conditions are stated in Article 3.6.3.2.)

My third and final question: the curtain aces (alpha s) are in the 0.86 state. In this case, is it necessary to soften the curtains a bit, that is, by keeping all the forces at 0.75, not the curtains. Is it better to transfer the rest to the columns. Because when the alpha s comes out at 0.90, the columns get very little cutoff. What can you say as a comment to this situation. Would you pay attention to this situation in the projects you have done. Take it easy, have a good work...

The higher the alpha s ratio, the more shear force the Curtains receive. If Alpha is S>2/3, then the ductility level can be easily solved by choosing a mixed system and taking R=6. Mixed ductility means that the walls are highly ductile, and the solution is made according to the normal ductile conditions of columns and beams. In this case, more economical dimensions can be obtained in columns and beams. We wish you good work.

Thank you very much. Then this is what I understand from this situation: Since the system is u type, different solutions will be made for each different type. For the basic system, the structure will be solved as a whole (again with dilatation). 0555-612-85-29
