Asthma Cat

[sadikcafer]

Hello, I am uploading the project, it is a very troublesome project, there is a mezzanine floor, I could not define the mezzanine and I tried to solve the problem by playing with the beams, columns and elevations, including the stairs, I guess there was no room. Basically the stairs are visible, only the columns are visible on the 4th floor, when I get the drawing, the mezzanine overlaps. I couldn't find anything about the mezzanine floor in the forum, I think there is a serious lack of information about the mezzanine floor. I would be happy if you look at it in general. Thanks..

Hello, define your Mezzanine Floor as a separate floor in the Floor General Settings Dialog. Good work

I defined it, this time it doesn't analyze??

I analyzed, I fixed all errors, but I could not fix this error WEAK FLOOR = FLOOR FLOOR, ni < 0.60 increase system rigidity The ratio of the sum of the R coefficient 7 and the wall shear forces to the total base shear force is greater than 0.75. What can I do, I posted the last version of the project in the message above, I would appreciate it if you are interested, thanks

I have defined it, this time it does not analyze ??

The system cannot be resolved message is due to the combination of the P18-P11 panels in the 1st and 2nd basement floors. If it is defined with offset, the problem is solved Note: *It is recommended to model the panel objects as shells *Review the warnings in the geometry control.

*B1 (Weak Floor) Irregularity occurs when the effective cutting area on a floor is less than the value specified in the regulation when compared to an upper floor (TDY 2007 item 2.3.2.3) Variables in the shear area are shears, columns and walls. There are columns and walls that are not connected to beams in the basement and ground floors in your project. Columns and walls that are not connected to beams and basement walls are not included in the effective cutting area in the program. If you think it should be included in the effective shear area, check the +Awx, +Awy, +Agx, +Agy columns in the Analysis/Floor parameters/Irregularities tab. You can add column curtain areas. *In case the AlphaS value is greater than 0.75, the R coefficient is calculated from the formula R=10-4*AlfaS according to TDY 2007 item 2.5.2.2. In the program, the shear force rate on the walls and the value of 10-4alfaS are given under the title of Earthquake Regulation General Report/ Reason for Choosing R Coefficient. Note: In order not to include the curtains that do not continue on all floors in the alfaS control, you can select the option -Flood/panel that does not continue on all floors- in the Curtain Properties/Static-Reinforced Concrete Tab.

I defined it, it does not analyze this time ??

The system cannot be resolved message is due to the combination of the P18-P11 panels on the 1st and 2nd basement floors. The problem is solved if the panel objects are modeled as shells or if the offset of the P18 panel is defined with an offset of 15 cm. Note: *It is recommended to model panel objects as shells. *Review the warnings in the geometry control.

Thank you for your information, Mr. Levent, I have taken into account your 2 warnings in the note. I have one last question; Is it healthy for us to enter the fixed and live loads of the ladder into the beams carrying the ladder?
