Seismic resilience of plywood-coupled LVL wall panels

Structural wall panels Laminated veneer lumber (LVL) have been proposed for enhanced seismic resistance of multi-storey timber buildings based on research performed at University of Canterbury, New Zealand. The system is designed to be self-centering with unbonded post-tensioning and dissipate energy through ductile connections. This paper describes the experimental and numerical investigation of one such arrangement with post-tensioned LVL wall panels coupled with plywood sheets.

Vibration control of steel liquid storage tanks equipped with Inerter-based isolation systems

Base isolation represents a very widely used strategy to mitigate the effects of earthquake excitation on structures. However, it can induce high displacements between the isolation
layer and the ground, which may cause serious damage, and even heavy and dangerous consequences in case of industrial components. Among them, big steel tanks for storage of petroleum
or other chemical products, should be considered very carefully. Moreover, isolation technique

Design criteria for dissipative devices in coupled oscillators under seismic excitation

Design criteria for a visco‐elastic connection of two simple oscillators under seismic excitation are proposed. The dissipative connection is described byKelvin–Voigt rheological model. The features of the selected criteria are explored for the system parameter set based on the analytical solutions of the associated eigenvalue problem and to the closed‐form solutions of the stochastic system response. Design maps are drawn in the nondimensional space of the relevant system parameters in which a direct comparison of the obtained design values is possible.
