wall loadings in etabs
wall loadings in etabs
(OP)
Hello,
I am using Robot Millenium software for a couple of years now and I'm just wondering if ETABS can do the same capabilities in putting various load scenarios on a wall(see attached file).
Fig. 1 - Normal to the wall point loads(how do you create nodes in ETABS to put the nodal loads?}
Fig. 2 - Increasing pressure loads normal to the wall.
Fig. 3 - Increasing pressure loads on part of the wall
Fig. 4 - Normal to the wall point loads with moment.
Any help will be greatly appreciated.
Regards.

Point loads on areas cannot be assigned directly. This is obvious.
"Let's try not to offer explanations if we are not sure about them." -> very smart.

2. Increasing pressure loads normal to the wall - Since ETABS lacks the joint pattern feature like SAP2000, this can be accomplished by meshing the wall and assigning different pressure loads at different heights on the meshed wall panels, which is a bit less convenient than using the joint pattern feature, although it can be done. There is a joint pattern example described in the A to Z example problems if you look at example H. I am guessing that the new version of ETABS will offer this feature since it's been part of SAP2000 for quite a while.
3. Increasing pressure loads on part of the wall - same as described in #2. You would mesh the wall and assign different pressures wherever you want. Those pressure loads by the way, do not have to be normal to the wall, they can be in any direction along the wall's local axis or global axes.
4. Normal to the wall point loads with moment - same mesh procedure as described in #1. Select the joint(s) and assign forces and moments.
In Robot or ETABS, the results will depend on the mesh. Robot appears to offer some automatic meshing for walls. How that mesh is applied will make a difference.

I think that you have heard of the difference between a point and a plane.
These should be clear to you. Then we can have a nice and constructive discussion about your issue. If you need any help kindly let me know.

Your statement upthread that "none of your 4 cases is supported" by SAP2000 is demonstrably incorrect.
If I missed something, please tell me what exactly, and be specific without smug commentary.
