In this study, the behavior of tannin-modified and pre-heat treated wooden beams in different
climatic conditions were determined. For this purpose; Samples prepared according to TS EN 386
standards from Scots pine (Pinus sylvestris L.), oak (Quercus petraea L.) and chestnut (Castanea
sativa Mill.) woods were impregnated with acorn tannin and pre-heated for 2 hours at 150°C and
160°C. After the samples were conditioned at 20°C temperature and 65% RH, 40°C temperature
and 35% RH, 10°C temperature and 50% RH, bending strength tests according to TS 2474 and
modulus of elasticity in bending according to TS 2478 were applied. As a result; At the level of
wood species-process type interaction, the highest increase in bending strength was determined
as 7.6% in tannin modified scotch pine samples at 150°C compared to the control samples.
Accordingly, it can be suggested to use Scotch pine wood in the manufacture of lightly loaded
wooden house columns and beams and other building elements
