Re: Beam Repair Advise

[Subject Prev][Subject Next][Thread Prev][Thread Next]
        Why should it fail if it is properly designed and installed?
        When I've done this the channels have been full length and properly connected to the end supports (usually a concrete basement wall or a steel columns) and bolted through the existing wood beam at three foot centers as near as practical to the top flange to prevent lateral torsional buckling.  The two channels back to back (with a wood spacer) are designed to carry all of the load.  The channels are jacked into place so that the load is applied by direct bearing; the bolts are not used to transfer load from the existing wood beam to the new steel beams.
        The existing wood beam is left in place to act as shoring during the installation of the steel channels.  If you remove the wood beam before hand you have a lot of expensive shoring to construct.
        If you think this is wrong I would like to know why so that I can correct the problem the next time the problem occurs.

If the contractor uses this method, I?m sure Bob Powell would love to know the address. Once it fails, I?m sure he could use some Expert Witness Testimony pocket change to supplement his retirement.

Irv, and Dave,


        Why take it out?  just add a C shape on each side for as long as needed (end-to-end if necessary).  If necessary install them in sections and splice them if necessary.
