dc.description.abstractThe article covers the cyclic lateral performance of a new hybrid timber shear wall called GLUlam-Frame OSB (GLUFO), composed of glulam frames connected to OSB (Oriented-Strand Board) sheathing panels and conventional nails. The key constructive detail of this new wall relies in that the OSB sheathings are embedded at grooved glulam members, which largely enhance the lateral strength capacity and stiffness of the element than the conventional light-frame timber or Cross-Laminated Timber (CLT) walls. The experimental campaign includes the Framing-to-Panel (F2P) connections and full-scale wall testing under cyclic loads. The wall failed due to a horizontal tensile fracture along the top beam, mainly caused by insufficient nail spacing. However, the wall reached a lateral drift of 1.48 % and a ductility of 5.8, which could have been higher if the failure had not occurred. Moreover, the proposed wall is three times stronger and stiffer than a conventional CLT wall and comprises one-fourth of the wood amount (0.89 m3) compared to a CLT wall of similar strength capacity. Finally, the proposed wall was characterized by a nonlinear macro-Finite Element (FE) model, whose F2P connections were simulated with the MSTEW hysteretic model, and three Single-Degree-Of-Freedom (SDOF) models, each with a different hysteretic model from the literature (MSTEW, DowelType, and ASPID). All numerical models show an error of up to 8 % for the lateral strength capacity, while the SDOF models are more precise for the energy dissipation prediction, with a error lower than 4.3 % and R2 for their history over 99.5 %. Hence, both numerical models provide a feasible alternative to simulate this new wall prototype.
