Description:
The unique feature of shear thickening fluid (STF), which shifts its phases from liquid state to solid state under dynamic loading, recently peaked attention in literature for shock absorbing systems or dashpots. Owing to phase shifting capability, employing STF as a vibration-damping system (VDS) can upgrade the performance of the structures under low probable dynamic actions (or accidental load). Therefore, a novel approach [i.e., STF-damped structural system] can tune the deficient structural system to a resilient one. Namely, an efficient, viable, and feasible rehabilitation solution for deficient structures can enhance the seismic performance of these structures by converting the kinetic energy of the shock into another energy form in the damper. To this end, the project proposes a novel approach, using STF to damp structural vibrations. Within the content of the project, STF working under a low strain rate and frequency is first synthesized. Then, the mechanical properties of the STF are obtained under dynamic load, which will be followed by a development of a damper filled with synthesized STF. Finally, real-time applications such as lab scale tests of STF dampers and computer simulations are targeted.
