Characterization of rolling-shear creep for cross laminated timber panels

Abstract : This article presents an experiment to characterize the rolling shear modulus Gr,mean of CLT panels and its creep. A four-point bending test is achieved on sandwich beams with skins and wooden core. This allows to isolate the CLT cross-layer and to characterize the shear behaviour. The experiment is performed in a constant environment during 6 months. The short term G0r,mean is estimated at 97.7 MPa with a coefficient of variation of 7.2%. Then, a power law is fitted to the results and the creep coefficient kGdef is estimated as 2.3 at 50 years which corresponds to a long term rolling shear modulut G∞r,mean = 29.6 +- 2.6 MPa.
