Re: Repair of Water Damaged LVL Beams

[Subject Prev][Subject Next][Thread Prev][Thread Next]

In working with heritage buildings I have had to deal with this problem with built-up plank beams several times. David Topete's advice is sound. My preference would be to use channel rather than plate if possible.

        There are other possibilities worth considering.  These include:

1.) Sister another LVL on one or both sides

2.) LVL's are very strong in shear, hence, one of them may be sufficient to resist all of the shear at all locations. If so, just replace that portion of the bad lamination where necessary. Alternative: scab a side plate using LVL material long enough to develop the section in bending.

After you've had a look you may have some other ideas or questions.

You're best bet though is to sister on steel plates or channels to assume
the loading, and check the LVL's to assume the full shear at their
supports. After the LVL's have dried, and the water source has been
fixed... :-)

My supervisor asked me to take a look at some water damaged beams at his

deep beams sistered together.  One beam has experienced a fairly large
loss of section and some of the others have small areas that appear bad.
Other than
complete replacement ( with its associated $$$) are there any ways to
LVL lumber?  I realize that the beam that has lost a lot of its section
will need replacement.
