Clay masonry façade (CMF) backed by traditional wood framing (TWF) is a popular method to form building envelopes in residential construction. Recent research thrusts show that unlike current practice (where the contribution of the façade to the system resistance is neglected), the masonry façade does contribute to the energy dissipation and stiffness of the system. This research investigates the earthquake behaviour of CMF with advanced wood framing (AWF) backing. AWF uses less material and provides more room for insulation in the structural envelope, lowering life-cycle energy demands and creating a more sustainable construction method. To establish the strength and deformation characteristics of the system, one TWF-CMF wall and one AWF-CMF wall, designed to standard building codes and coupled with corrugated metal brick ties, were subjected to reversed-cyclic in-plane loading. Comparisons of the wall behaviours are used to investigate the seismic resistance and provide design recommendations for a resilient combined system.
