Abstract

This article presents an experiment to characterize the rolling shear modulus G_r⁰ meanof CLT panels and its creep. A four-point bending test is achieved on sandwich beams with steel 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 G_r⁰ 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 kdef G is estimated as 2.3 at 50 years which corresponds to a long term rolling shear modulus G_r^∞mean= 29.6 ± 2.6 MPa.
