I noticed that the BS8110 AND Eurocode2, suggested some tables of coefficients (Table 3.14) to calculate moments occur in two-way slabs. But they are rectangular, and further I noticed they can't be used if the slab length is more than twice the width.
What if I have a triangular or...

Yeah I get it needs anchorage at the supports.
Other than the anchorage at the supports, the top r/f is ok?
I'm trying to understand the concept as well.
And how to calculate the distance 'x'
I have calculated the following for a slab. Obtained the area of steel required in accordance with the eurocode2.
It has fixed end supports.
Compression r/f were not needed. The top reinforcement shown below are for the hogging moment.
I have calculated shear r/f needed as well, but didn't...
In the Eurocode 2, to calculate minimum reinforcement, there's the following equations.
For the concrete grades above C50, the last formula is used. However, it contains "Ln", does it mean effective length of the beam, slab etc? Or something else? I didn't notice the definition is given...
Thank you for your reply.
Yes I was correct it seems, it can create issues if the concentrated load is large enough.
By the way, you had referenced the 'Australian Standards". I must mention that I feel "Australian codes" are one of the most organized and clearly explained engineering codes...
I felt the 'strut angle' can be like more than '45 degrees' (for the red concentrated load) and it can directly transfer to the bottom area before the supports.
Because, we are designing the beam for the shear load at a distance at "d" at that point the angle is ok, but we have a very large...
Thank you for your reply.
Old textbooks might also be wrong/outdated anyways. Old research often being replaced with new research :) I felt it's odd to blindly follow "distance at d" rule.
I felt like if the concentrated load is large enough and near to the supports it can create issues. So I...
