“…In addition, economic losses could be particularly important. For this reason, different institutions, electric societies and the civil protection have often stimulated the interest of researchers on this topic, funding research programs devoted to a preemptive assessment of electric failure caused by a seismic event [5,6], and to strategies for reducing the consequent risk [7,8].…”

“…In addition, a torsional hysteretic damping device was used into the retrofit design of existing silo structures in studies by Pinkawa et al The conducted incremental dynamic analysis results showed its effectiveness in preventing the global sideway collapse failure mode. Paolacci et al compared the efficiency of base isolation, energy dissipation devices, and traditional tuned‐mass‐damper device in seismic response reduction for chemical process plants by means of numerical simulations and physical tests. Noted that, most prior studies discussed the performance of seismic mitigation strategies in the aspect of structural behaviors and few built a link with the seismic risk.…”

Summary Electric power system is one of essential lifeline systems for an urban community. An actual power plant building with typical coal‐fired power generation process is selected to be studied in this paper. The detrimental impacts on the seismic performance of the structural system induced by heavy coal bunkers and irregular bracing configurations are expected to be mitigated by using retrofit strategies. A total of three retrofit design schemes that employ the isolation and supplemental damping techniques are developed. The original design scheme of the actual thermal power plant building that adopts steel special concentrically braced frame as lateral‐force resisting system is used as benchmark for comparison purposes. Nonlinear response‐history analyses are performed, and the obtained seismic responses are compared. To better quantify the benefit of the considered retrofit strategies, seismic risk in terms of probabilities of exceeding designated damage states as well as the downtime are analyzed. For the studied thermal power plant building, the results show that the added damping system is more effective in seismic risk reduction than the isolation for heavy coal bunkers. Compared to the original structural system design, the use of supplemental damping system cut the downtime of the thermal power plant building at most 42%.

“…The solution based on wire ropes is particularly suitable when the period, differently from the devices traditionally utilised to protect buildings and bridges (elastomeric or SSBs), is elongated by a rocking effect rather by horizontal shear deformations [25]. They are simple devices consisting of twisted stainless steel cables wound around drilled aluminium alloy bars.…”
