Failure and deformation of full-scale light frame poplar and spruce walls under vertical compression and shear load

Wood frame houses are usually made of softwood species in Europe and North- -America. But many countries have a great population of different hardwood species, e.g. poplar. This study investigates the possibility of using poplar, instead of pine for wall frame construction of lightweight houses focusing on the mechanical properties of the panels. Vertical compression tests and cyclic lateral shear tests were done using full scale light frame panels. Results show that the poplar panels have unexpected strength; the compression failure force of poplar panels [316.02 kN] is no more than 6% lower than spruce panels [335.00 kN] and no significant displacement was found at the moment of breaking. Poplar panels show more flexibility and lower deformation values during the lateral shear cyclic and the moment of failure, although the failure force was slightly higher in the case of spruce panels.
