i want to take out a load bearing wall and relace it with columns to open up the floor plan. How much wieght would the load bearing wall have held if it was an 8 foot wall with 2x4's 16" OC? The colums I am using support about 10K pounds each and I am thinking of using two. The only thing above is a bedroom that the bearing wall was supporting. Is there a formula for calcuating how much weight a 2x4 framed wall supports. Thank you!
