1) Similar to the emerging trend of BIM-only deliverables (ie no 2D drawings), do you think we'll reach the stage where all of our calcs will be sat within an analysis model file rather than printing out 100s of pages of output? In my opinion it's much easier to whiz around an analysis model to...

Thank you all, great responses. Re punching shear, here is a guidance based on EC2, which is very similar to what hetgen showed:

200mm thk wall; 3m; 10 levels The "hidden" column approach is interesting. What I am conscious of taking an overly narrow depth leading to an overkill of shear reinforcement. Though probably the same can be said for going too wide and providing too little.

Trenno, it is the width of this hidden beam that I am most interested in. I am unsure about whether taking the column strip would be unconservative. For bending I am taking a much smaller thickness, based on this (found in BS8110): And taking x at the middle of the wall.

Thanks KootK; interesting read, will review over the weekend. First post, will try to give more detail in the future. All RC concrete. This is happening at a few places; distance to wall is between 250mm and 2m.

No transfer column. It's a wall transferring along the green line.

Please review the attached sketch. I am curious to see what others would do to check shear in a situation like this: I would think that one-way shear would also be quite critical but cannot find any guidance on what effective width of slab to consider. Thank you in advance.
