Experimental investigation of OSB sheathed timber frame shear walls with strong anchorage subjected to cyclic lateral loading

Abstract Sheathed timber frame shear walls (STFSW) with strong anchorage have recently been studied to be used as the main lateral force resisting system in buildings. The first part of this research project highlighted enhancement stiffness and strength STFSWs comparison established configuration light-frame under monotonic horizontal loading. In paper, in-plane seismic behavior was further investigated by means quasi-static cyclic loading tests on large-scale walls. boundary conditions specimens were considered more realistically applying a combination vertical bending moment top addition ISO 21581, tested new protocol especially developed for low-to-medium seismicity regions. showed marginally higher resistance Nevertheless, terms ultimate displacement, they did not evidently perform well when subjected Withdrawing staples failure stapled connections resulting out-of-plane displacement sheathing panels, which clearly observed 3D digital image correlation measurement system. low-to- moderate highly influential their capacity.
