infill walls

Post by by kaman »

Hello..
I'm doing a master's degree .Now,I study to prepare a thesis. I'm examining a heavily damaged building with using Seismostructure in my thesis. The first floor of the building has infill walls with ribbon Windows. There are columns next to the windows in the infill walls So the column behaves like a short column at the time of the earthquake. I used building wizard when designing the infiil Walls .However, after the analysis, the walls had no effect on the columns and so the columns don’t behave like a short column. Is there something I'm modeling wrong or missing? Can you help me ?

Hi ...I examine thıs form then
I noticed the deficiency in my project...This is rigid connection ..Then I tried and
I got the result I wanted when I assigned a rigid connection with columns to the parts where there are walls in the constraints section of the preprocessor.
I think My problem is solved...
Thanks....

Note that you can use the Building Modeller to model RC frames with infilled walls of any height. If the infill is lower than the column height, the Building Modeller automatically subdivides the column and forms the short column

Hi..again yes you right.. If the infill is lower than the column height, the Building Modeller automatically subdivides the column and forms the short column..And In the section in the preprocessor, the column is output as divided into two parts.But I dont want it.I want to examine my column as a single section .. How can I ?? Can you help me???

Dear by kaman,

The first post you wrote was about modelling the short column. If you do not need to model the short column anymore, then you should either assign the infill in full height in the Building Modeller, so that you will get a single column in SeismoStruct, or you may delete the short columns within SeismoStruct and modify your model accordingly.

I didn't want to model the short column.I wanted to show that it behaves like a short column.
I wanted to show that there is a lot of force coming to the column part in next to walls which have ribbon windows.

Yes I did.I deleted the short columns within SeismoStruct and modify my model accordingly.But the effect of the walls after analysis did not appear in those columns..
Now If Iuse link between the wall and the column, can I observe the effect?

To the best of our knowledge, the only way to effectively model the effect of the short column is to subdivide the column in two elements, one which is close to the infill and one at the free height (i.e., the short column).
