beam numbering system
 

beam numbering system
there was a querry for column numbering system. what is the accepted numbering system for beams?
find a job or post a job opening
i'm not sure there is one... i usually use the prescript 'b' to denote a beam and then the first digit signifies the floor or area, for example beam b211 would be on the second floor (br211 would be a roof beam). i also use the format bfnn for all beams unless i anticipate more than 99 beams on a floor, in which case, i would use bfnnn as the format. i also try not to locate b211 at some isolated location that is outside the sequence of beams in the area. if beams are similar, then i use the same mark number. the reference to the size (and or reinforcing) is either on the plan as:
12x24 bm
2-15m t
2-20m b
1-20m6.6 tx at sup (top extra at support)
6-10m@10, rem 10m@24
typ all bm mk b211
or in a tabulated schedule beams noted on the plan as b211. for something with that many different beams i'd likely use a schedule.
if steel, it would be:
w250x33
typ all bm mk b211
and i likely wouldn't use a schedule.
good man, dik! i really wish everyone approached structural detailing as such and fought to maintain the logic as long as possible, especially on very large complex projects.
i think it is also very important to avoid naming post tensioned beams and conventionally reinforced beams (in concrete) with similar names. before i graduated from ga tech, i spent most of my time detailing formwork shop drawings. i recall one job where the beams designations were pbxxx and pbbxxx, one pt the other conventional. if it confuses those in the office, the field will feel a greater hurt.
