The increasing demand for mass timber use in buildings has led to the development of post-tensioned self-centring mass timber shear walls. These walls are lateral force resisting systems that place unbonded post-tensioned steel rods in parallel with timber wall panels to create a system that re-centres after an earthquake. Since their seismic testi...
