System Tipping Moment with Limited Ductility Level

[osmanbayrak]

Hello, When I solve the carrier system shown below, it does not give a problem with the 75% tipping moment.

But the regulation; As seen below; 4.3.4.6. If it is limited in article (4.3.4.7), equation 4.3, that is, 75% rule, if it does not, it wants a mixed system. Why does İdecad accept its limited selection here? Thank you for your interest.

Hello, It is stated that if the alpha(m)>0.75Mo condition is not met in the limited system selection, the R, D and BYS conditions of A31 will be applied. So if it is not provided, you do not have to make a mixed system. See: 4.3.4.7 after 4.3.4.6 ideCAD currently does not give a warning if this condition is not met.

Hello, It is appropriate for the program to accept limited selection of A31 ductility level. As Erhan said, it is stated that if the alpha(m)>0.75Mo condition is not met in the limited system selection, the R, D and BYS conditions of A31 will be applied. If this condition is not met, you do not have to make a mixed system. To analyze with R, D and BYS conditions of A31, run the TBDY Analysis settings wizard, select the A31 system and analyze again.

The Chamber of Engineers says you can't solve the limited in any way. They don't interpret the articles that way either.

The Chamber of Engineers says you can't solve limited in any way. They don't interpret the items that way either.

The Chamber of Engineers says that you can do limited in dts3 and dts4. dts1 and dts2 are either mixed or ductile in accordance with the regulation. ( 4.3.4.3)

Hello. In my previous message

I wrote TBDY Analysis settings wizard to analyze with R, D and BYS conditions of A31, select A31 system and analyze again.

I wrote DTS in analysis settings wizard conditions are checked.A31 structural system type selection will be passive except for DTS 3 and DTS 4. If you cannot meet the alpha(m)>0.75Mo condition, select High Ductility level and continue with your project.
