yes RB stands for Roof Beams. Beams are identified by IDs like beams on ground floor are GB-01 to GB-n and so. From this figure,"u/s" can mean up-stand beam which is the inverted beam, where slab fixes with the bottom of beam, other types are down-stand (conventional type) and up-turn beam. But you also need to see other notes, plans and elevations pertaining to this project for more information. Dashed (dotted) lines show the edges of members not visible at this Level (the roof level). They may be at any level, figure them out using other plans and elevations.

AoA everyone ! I want to know that is there any minimum & maximum reinforcement ratios for section of Raft footing ? Any Code or Reference. Also if you can provide your steel quantity consumed to Rraft concrete quantity ratios. Regards

Dear Members I am working on a project site where Column Reinforcement is as shown in the file. The Columns (C6 to C20) are going from +12'-0" to +48'-0" un-braced and without any slab at intermediate levels. The slab is at +12'0" and +48'0" level. The Reinf is changing and larger dia bars are provided on top. I want to ask that is it alright and what is the possible explanation of changing the number and dia of bars in-between ? Regards Column Reinf 1.pdf
