Shear spring model proposed for seismic evaluation of a timber framed masonry infilled wall

Interaction between timber and masonry is difficult to assess and although numerical models simulate roughly the seismic behavior of TFM, they need expensive resources (time and software) to reach acceptable accuracy level. For this reason, this study proposes a simplified seismic evaluation method for timber framed masonry walls, based on a shear spring model calibrated with experimental result. The resulting envelope curve simulates satisfactorily the initial stiffness and maximum strength.
