I'm removing a 20' load bearing wall in a -level home in

Customer Question

I'm removing a 20' load bearing wall in a bi-level home in NJ. The wall supports one floor and the roof. I've determined a 1/2" flinch plate sandwiched between two 2" x 8" x 20' would be adequate. What is your advice?

Hello. I'll be happy to assist you.
How did you determine a 1/2" plate with the 2x8s will work. That seems very small and I don't believe it will work when I check it.
Expert:  StructuralEng replied 2 years ago.
That size flitch plate beam is not even close to working. How did you arrive at the conclusion that beam is acceptable?
I can size a flitch plate to minimize the depth, but it will be deeper than 7.25" deep.

What information do you require to determine the correct thickness and number of flitch plates,while using 2" x 8" x 20'?
Expert:  StructuralEng replied 2 years ago.
You can't use 2x8s. The plate thickness is too much - over 3". If you want to stick with that depth you will need a custom I beam designed and it will be very heavy and inefficient.

I can offer the custom I beam design as an additional service.
