Experimental Investigation of 3D-Printed Elastomeric Dampers
Publication: Lifelines 2022
ABSTRACT
The increasing use of tall buildings worldwide has led to rising demand for strategies to control lateral displacements in these buildings. Viscoelastic Damper (VED) devices are passive systems that depend on energy dissipation through a constrained viscoelastic material. This study aims to study the effect of angle orientation of the infill pattern on the energy dissipation of the 3D-printed Thermoplastic Polyurethane (TPU) VED device. The mechanical and viscoelastic properties of 3D-printed TPU with a rectilinear infill pattern printed at three angles were investigated using cyclic uniaxial tension tests. The VED with 3D-printed TPU was subjected to sinusoidal signals with varying frequencies and strain amplitudes to examine its energy dissipation capabilities. The tests showed that the 3D-printed VED is capable of dissipating energy with good efficiency.
