Structural restoration of wooden beams by means of epoxy resin
- 104 Downloads
The structural restoration of deteriorated beam ends by means of epoxy mortar is discussed. The results of a test programme are presented: determination of bond strength as a function of the degree of humidity of the wood; anchoring strength of glass-fibre reinforced polyester bars and steel bars, glued in wood or in epoxy mortar. A comparison is made between the results of these elementary tests, and the behaviour of restored full-size beams. The phenomena leading to rupture of the structural element are described, in order to define the direction of future research.
