Thank you a lots for your video. Great explanation. I will have to watch again to fully understand the different concept. I note that you are using a Grade 25 concrete with 20 mm. cover while as far as I know BS8110 in one table consider only Grade 30 as minimum with a cover of 25 mm. for mild weather type. I compared this with IS standard 456-2000 where they have Grade 20 as minimum for reinforced concrete. There is an author A. Allen who inferred that Grade 25 is permitted in BS8110 through it is ambiguous and not that clear. Another issue I found while am studying all this is the formula for steel required where in some books they have 0.87 (Chanaka Arya, IStructE) and 0.95 (BS8110, McKenzie, Higgins & Rogers). This is based on different values for partial safety factors. It seemed that there is an update to BS8110 but still unsure about that. I have also been looking for the 1985 edition of BS8110 and CP110 without much success to check the value there. Many thanks for your video.
Hello viewers. To learn how to design this slab in excel using customized excel sheets consider the link below. th-cam.com/video/81rO6jCg2i0/w-d-xo.html
If you want your slab to bear load you can add the load to your additional dead load in load/sqm or use exact loading like line load or point load. The other process remains the same. If there is excessive concentrated load you might need to check for shear resistance at the load positions
Amazing lesson Sir. Massive thank from italy. It was exactly what i was looking for. Opened my mind. Massive massive thank u
@@lupocattivo8777 Thank you for your response. Kindly subscribe to our channel.
Thanks for the insights. Kindly have a class on same slab design with Prokon software

i like the way u are preparing sir
can i get this lesson as pdf pls
Hi Brian. Have you done any design for ribbed and waffled slabs? Please do one.
hi does this design can approved in load bearing slabs
If you want your slab to bear load you can add the load to your additional dead load in load/sqm or use exact loading like line load or point load. The other process remains the same. If there is excessive concentrated load you might need to check for shear resistance at the load positions
How about the design for hollow blocks slab
Hello. That is in plan. We will post that video once we are done with the design.
