It says solve your system semi-rigidly

friends, there are 2 problems on my mind 1-) I saw that the projects are generally solved as fully rigid, some say solve the system as semi-rigid... what is the difference between them as a system 2-) I took the R coefficient 7 and solved the basic apl. When I want the plan, it shows Rx=6.98 , Ry=6.98 how should I interpret this?

1-) Examine this title for the 1st question; [ url=http://www.idecadsupport.com/forum/viewtopic.php?f=5&t=1426&p=7943&hilit=YARI+R%C4%B0J%C4%B0T+D%C4%B0YAFRAM+NED%C4%B0R# p7943]viewtopic.php?f=5&t=1426&p=7943&hilit=HALF+R%C4%B0J%C4%B0T+D%C4%B0YAFRAM+NED%C4%B0R#p7943[/url] 2-) Curtained frame and high In buildings designed at the ductility level, the R coefficient is 7. However, in case of B1 irregularity in the system or the ratio of the shear base shear force to the total floor shear force is greater than 75%, the R coefficient should be reduced according to the formulas given in the regulation. coefficient automatically decreases, otherwise you have to intervene manually. Since the program gives 6.98 equal in both directions and calculates it by itself, we can say that your system has B1 irregularity. If you add your project, you can see where the problem is.

Since the curtains on the basement are marked as basement curtains, they are not included in the effective cutting area of the basement. Also, since no wall load is entered on the basement curtains on the ground floor, the wall on the ground floor is not included in the effective cutting area. area is calculated less than the 1st floor.You can intervene in the wall and curtain effective cutting areas in the Analysis/Floor Parameters/Irregularities Tab.

Due to time constraints, I couldn't look into it in detail, but there is a borderline B1 irregularity on the ground floor.I don't know the architecture, but B1 because the wall area on the 1st floor is about 3 times the ground floor Uncheck the 'Flooding' sign of the curtains in the Y direction on the basement floor. You do not need to mark the Y direction as rigid already in the basement. You do not need to mark the wall area on the ground floor from the Analysis--->Floor Parameters---->Irregularities section Akx and Aky B1 problem is solved.Also, your column area on the ground floor seems more than the basement, you can examine it.
 
Re: QUESTION ... When I searched the forum for a bit, it is said that if there is only a curtain in the basement, it should be marked as a basement. I need to enter the frame wall load. If a 19 cm brick is used, I have to enter my value of 0.8 tf/m there.

The expression is misunderstood or written incorrectly. First of all, marking the panel object as a subbasement does not affect the analysis results. Walls marked as basement are not taken into account in alfaS control and b1 irregularity control. If your floor is considered rigid, there is no need to mark the wall on this floor as flooded. Akx and Aky are the area, not the wall load. The wall length* is found from the wall thickness. Press F1 in the floor parameters dialog. You can get help by pressing. If there is a point that is not understood, you can contact by phone. Tel: 0-224 -220 67 17
 
Re: QUESTION ... you said that if we accept the bidet basement as rigid, we don't need to take it as a basement, you said that basement curtains are only rigid in Y direction in this project.

You need to write the total wall area on this floor as the effective wall area in this column (The fields that need to be entered as additional values are columns and curtains) Aky= The current wall area in the B1 irregularity report (1.54) m2 + the wall area on the curtain (1.398m2 )=2.94 m2 Also, if there is a wall on the left side curtain, that area should also be included.
 
Re: Question ... Sir, if there was no B1 irregularity in the system, would we still add these values to the curtains as a load?

Entering the wall load on the curtains as an additional load However, the additional load entered on the curtains in the program does not affect the B1 irregularity.Information about the load definition on the curtain can be obtained from the link below.

Re: Question ... Professor Levent, I said I can apply this on a new project, I checked the link you sent, this time I can't get rid of the following errors

*Total Nd>0.45*Total Nk warning is due to incorrect formation of raft boundaries. The raft is outside the floor boundary. Create the raft boundaries to include all of the columns. *Rigid in the Y direction of the basement floor is not considered rigid in the X direction. Since the curtain in the X direction is not marked as "flooding", it is included in the alfaS control." . If the panel objects on 3 axis are marked as basement curtain, they are not taken into account in alfaS calculation. Note: No load is defined on the basement perimeter bulkheads.
 
Re: Question ... I added a load to the basement perimeter curtains....why do we mark only 3 axis curtains as sub-flooring?
 
Re: Question ... *If you are talking about the value you entered in the Akx and Aky columns, they are not the load, they are the effective shearing areas of the wall. Please review the relevant regulations first. *The walls in the y direction where the relevant floor is considered rigid in the y direction are not included in the alfaS control.
