We have a bi-level house and on the bottom level there are 3 beams right by the stairs (separated by about 15"). One of the beams is a steal beam (obviously load bearing). The other two are wood beams. We can hit the wooden ones with a hammer and they move slightly. We would like to remove the wooden beams, but are unsure if they are load bearing. How can we determine this? Any help is appriciated.
