Make videos like manual calculations plus cross checking of results and also make Excel sheets which will increase your ratings... Sharing the Excel sheets will boost up your channel

My displacement doesn't display in mm why?

AoA..hi dear please make video on Designing of basement wall which is not uploaded to youtube yet..or guide me about Designing of basement wall using Etabs.

Above the basement all shear will be taken by the core wall. Once the accumulated shear reaches the basement top slab, this slab will act as a support to the cantilever beam that is your building (with a distributed wind load acting on it). This is generally what happens when the soil surrounding the basement can be considered stiff enough as to prevent any significative displacements.. plus, if your building area is much smaller than your basement area and the basement walls are very large (which is common), the walls alone can act as supports restraining the basement from any significative displacement. So either way, it is important that you put restraints to your model at the basement-top-slab level. Like MrHershey said, you should think about what is most likely to happen in reality, most of the times you can determine this by visualising the building as a cantilever beam with any kind of forces acting on it.

use ETABS for analysis. I guess that the "panel" would equal "shell" in ETABS. If so, I think that is the way to go, since all shear collected above basement-top-slab level will be transferred to the basement walls by the basement top slab and the basement walls will transfer it to the soil around and under them. So you do not need of any special technique or modelling to capture this. Using shell elements to model the basement walls would be more realistic, simple and accurate. Hope it helps.

Thank you dear... But can you please make a video on what you told. Please make a video on this topic.

As the slab can be designed in csi safe or Excel sheets. As others designers only take the live and super dead loads and put that in sheets , so they deisgn the slabs like this.my question is ..If transfer the loads to columns then why they consider the loads from slab on basement wall..and the soil pressure will be there ..the problem is about coming of load's from slab to columns. If yes the loads must be taken on basement wall then how it will be taken.. please help regarding this issue

[@saeednegar709]

The second things is about Designing of stairs..how to deisgn the stairs.. modelling is different and design is different .many engineers says that it must be designed in excel sheets

[@anwarkhan-ep6fv]

Please upload the excell sheet

[@saeednegar709]

Another request for you is ..please bring some thing interesting to get more subscribers cause these topics are already uploaded to youtube ..so bring some interesting things to get more subscribers

ALL YOU HAVE DID IS WROOOOOOOOOOOOOONG

Please mention where is mistake ? That we recommend to etab ?
