Structural robustness in timber structures is a topic that is becoming increasingly relevant as taller timber buildings are built. To increase the robustness of a building and by virtue preventing disproportionate and progressive collapse, an appropriate design concept tailored for the properties of timber and its connections must be chosen. The most common way to assess the building’s resistance to disproportionate and progressive collapse is done through column removal analyses. However, the majority of such analyses are carried out by linear elastic quasi-static means. For other materials, literature reports significant dynamic effects for sudden removals of structural members. The dynamic effects increase for lower plasticity systems. Timber is a brittle material in shear and tension with limited plasticity. It is therefore important to quantify the dynamic effects for an adequate robustness assessment. In this paper, 216 nonlinear dynamic analyses are carried out on small planar timber skeleton frames in the finite element framework OpenSees to investigate the relation between the dynamic amplification factor and different structural parameters. The most important parameters are the damping ratio and the connection stiffnesses. The resulting dynamic amplification factors are between 1.9 and 2.0.
