What Macca says !
I think it is also referred to as "seating the beams".
Basically you make a very tight fit between the beams and beamlandings.
More tight then you can design into the hull mould.

Wow, you actually agreed with Macca on something! Is this the start of a new trend?
But I actually used to replace the bolts every 2 yrs on my ol' Taipan and reseat the beams. Used same method Macca described.
