trying to get use to using the span table book, i was confused on how i know what spacings my posts are suppose to span.
so if my floor load width is for example 1800 is that the spacing what my bearers should be? and then in the span table under 1800 FLW then i see what timber i should use to span longways? then find the joist that will span over the 1800 bearers.
am i on the right track?
