Seismic performance evaluation of steel moment frames infilled with plywood shear walls

This paper presents seismic performance evaluation and design of timber-steel hybrid shear walls consisting of steel moment frames infilled with plywood shear walls. The hybrid system can be easily incorporated into multi-storey light timber framed (LTF) buildings using construction materials that are readily available in the NZ construction marker. A finite element (FE) model of the hybrid wall system was developed with its critical input parameters calibrated by connection test database of nailed plywood-timber connections as well as bolted and screwed timber-steel interface connections. The FE model was validated against existing hybrid wall testing data and then used to conduct a parametric study to establish shear wall response database of the hybrid walls with various configurations in terms of steel member sizes, nail sizes, and plywood thicknesses
