Timber-steel hybrid beams have been proposed, tested and analyzed for their use in multi-storey buildings. It is expected that the use of steel will help to counteract the creeping behaviour of timber. A specific long-term test for timber-steel hybrid beams was designed and carried out during one year in order to verify this and other hypothesis. The hybrid beams were designed with an equivalent bending stiffness for the timber and steel components. The results were successful and showed that the hybrid performance can reduce, for this case of bending stiffness balance and after one year, the creeping values in approximately 50%, compared to the comparison pure timber beams.
