Rrigid ends definition

[simon_1000]

I want to consider the RC-joint rigidity in a two-story model. All of my elements are 35x35 cm. The values which I was applied were as follow:

Minimum considered length for column rigid ends = 0.175
Minimum considered length for column rigid ends = 0.175

When I create the corresponding seismoStruct model, in the connection zones, the following image has seen. Is it right? I think it's not. Please guide me to have a suitable model. Thank you.

It may be that you intended to specify "Rigid Offsets" in the Element Connectivity details? That is generally the manner in which rigid joint effects may be modeled. I confess that I am unfamiliar with the "Minimum considered length for column rigid ends" specification.

When I choose and define "minimum ...." , the rigid ends calculated and aoutomatically assined to the Element Connectivity details in the seismoStruct file.

Dear simon_1000,

From what you describe, i can understand that you have selected to consider rigid ends in columns within SeismoStruct Building Modeller settings with a minimum considered lap length for column rigid ends equal to 0.175m. When you select this option the program automatically creates rigid ends in column sections with a length equal to the larger height of the beams supported to the column. When the rigid end that is created in the abovementioned way has a value lower than the minimum specified one (0.175m in your case), the program will automatically delete the rigid end, i.e. no rigid end will be assigned to the specific column.

Thank you very much "z.gronti ". Your answer was very usefull.
