This thesis investigated cyclic behaviour of one type of timber-steel hybrid wall systems consisting of steel moment resisting frames infilled with plywood shear walls. A detailed finite element model was developed to model the hybrid wall behavior under cyclic loading. The hysteretic parameters of critical connection elements were calibrated by experimental testing results. Using the validated hybrid wall model, a parametric study was further conducted to investigate the effect of nail size, plywood thickness, bolt size and steel moment frame section sizes on the hybrid wall behavior. Overall, the hybridization of the steel moment frame and the plywood infill walls can provide significantly better performance compared with conventional plywood shear walls. Based on the results of the parametric studies, a brief design guide with a worked example was developed to assist structural engineers to use this type of timber-steel hybrid shear walls in muilti-storey timber buildings.enAll Right ReservedTheses / Dissertations
