Question
Please can you tell me what size RSJ i would need to support the knocking down of a external load bearing wall covering 17 foot.
The load above is the main roof of the house and about 30 lines of bricks which will need to rest.
Hi Sam, I'm not sure what the term RSJ means..A 17 foot span that you speak of should require a 16" beam..steel maybe a W16 x20, wood 6x18 minimum, concrete beam 8x18 with 6 #6 continuous rebar and #3 stirrups at 8" on center.. If brick is involved I would do the concrete or steel..I recommend that you consult a local engineer to see if there are other variables involved I am not aware of and to calculate your required load. I hope this information helps, please feel free to write again regarding this or other matters, sincerely bruce e johnson..bejohnsonconsulting.com
