wood column for steel column
i am currently working on a project where the contractor wants to replace the steel columns with wodden ones. has anyone worked with or seen a wood column large enough to handle a load of 50 kips with a length of 14 feet. i do not believe a resonably sized wood column for this situation exist but any advice or information would be helpful.
thanks
find a job or post a job opening
to get something with a decent size, i would think you would be into composite (psl or lvl) or like a 10x10 douglas fir.
is that 50 kips a service load or ultimate load. a lot of it will depend on column stability because that is really the largest reduction factor for wood column design. 50 kips is a very large load for a wood column.
making some assumptions (it is service load, cd=1.0 for ll, interior, no temp concerns, and only braced at ends (pinned)) and using doug-fir larch no.1, i am getting that you need a pretty healthy section (10x10)
it will be an interior column, pinned on both ends with the 50 kips being the ultimate load
50 ultimate? then i think it is doable unless they want to hide it in a wall.
never, but never question engineer's judgement
so 10x10 douglas fir would be acceptable?
also, can anyone give me a website that has different sizes and types of wood columns and what load capacities they can handle? thanks
a 10x10 doug-fir no.1 would be a bit overkill for 50 kip ultimate load. you can definitely come down from that. that was sized for a service load.
look in the nds supplement for capacities. i think the suplement is available online for free.
