Sir,

Kindly find the plan picture of the project.its a g+7 storey building. Assume all beams and columns are same size. And slan 125 mm thick. Shearwall 250 mm.
Total 8 shear walls. 4 at the coners . 2.5m each and 4 at staircase  1.235m each. Hw should i model this plan. Since shearwall is through wall from basement to roof. No beam comes above it in each floor level. I have watched videos in which beam is placed above shearwall at floor level.i think its a wrong practise.

Dear Engineer

First model the structure as per your requirement/dimensions
Then add shear wall at four corners using surface elements  and also for staircase area. Select all the beams by switching to front view,add auto generation of plates as slab with required thickness
lastly delete the columns/beams where ever your shear wall presents
Use translation command to generate number of floors
Finally assign properties,supports,loads , analysis and design command with necessary parameters...Done


I cannot say about those  shear wall tutorials, whether correct or wrong

good luck

Do you need shear walls, rather than straight away giving them, examine if its required, in fact suggest  you increase the thickness of component members for economy.
