Sometimes ETABS gets really hung up when there are 3 grid lines in the X-Y plane crossing at a single point, due to decimal inaccuracies (this often happens when you have grid lines at different angles, where three or more grid lines cross at the same point). Do you have this condition...
Hi All,
We're considering trying out ETABS V13 for masonry shear wall design, now that the program is supposedly equipped to properly model masonry shear walls. I'm wondering if anyone has used the program for masonry shear wall design and what your thoughts are on it, compared to the more...
@wannabeSE - Yes, typically the stiffners are provided for torsional stability of the for the extended plate. However, I've read that you can also size them to take the moment from the bolt group back to the column web.
@structSU10 - After doing some additional research, this is the conclusion...
The AISC manual is not clear about the difference that stiffeners make in locating the eccentricity. The debate is whether the "connection to the column" (eccentricity) has to be taken all the way back to the column web or just to the face of the column flanges/stiffeners. The research by...
I need to make a correction... RAMConnection DOES account for the eccentricity, but you have to input an actual load on the connection, as opposed to just looking at the connection capacity, for it to consider the eccentricity. I'm still unclear on where the eccentricity would be taken to (i.e...
Hello,
I'm currently designing some simple shear tab connections into column webs, which I believe are pretty common. We are using shear tabs that extend beyond the flanges of the column, so that large beams can attach without copes or erection issues. We are providing welded stiffeners at the...
