    Abstract:

    In order to study the load-displacement relationship of the timber bolted connection with slotted steel plate， monotonic tests were performed on 24 specimens in the direction parallel to timber grain， considering the bolt diameter， the dowel bearing length and the slender ratio. The experimental results show that the connection undergoes the elastic stage， elastic-plastic stage， plastic-developing stage and failure， performing well in terms of deformation. Based on the curve fitting， a two-parameter （i.e.，strength and elastic stiffness） mechanical model was proposed and theoretical formulas of the two parameters were derived. Finally， with the theoretical formulas and mechanical model， a calculation was conducted to obtain the load-displacement relationship curves of the specimens， which was found to be in good agreement with the test results.
