The issue of seismic retrofit of structures and existing buildings has become one of the most important issues in earthquake engineering. One of the most important issues in earthquake risk reduction strategy is to retrofit existing buildings with the lowest cost, high speed and with a good performance level, in order to maintain at least the lives of citizens in middle-to-high levels of earthquakes, and in fact, the threshold of falling buildings will be promoted.
Based on the goals defined in this research, the basics, reasons of need and different types of retrofitting methods have been studied and evaluated, then, the maturity level of several samples of the new seismic systems is evaluated by focusing on a more comprehensive scale means TRLs. Finally, quantitative and qualitative outputs including basic definitions levels until the operational dimensions and exploitation concepts is presented, as a final measure of The maturity of each systems.
Based on the results, by maintaining the basic concepts of the TLRs scale and making minor adjustments to the alignment of the level definitions with the each technology / system, it became clear that this tool could be used as an effective measure to achieve the measurement new seismic control systems and facilitated decision making. This scale, taking into account multi-dimensional criteria such as cost, time and technical issues, as well as the ability to combine their impact on the decision-making process, has the capability to cover the weaknesses of other methods and the one-dimensional and timely decision-making patterns.
Based on the results obtained, among the systems evaluated as a sample in this study, seismic isolators in general showed a more favorable maturity evolution than dampers. Also, through the selective dampers, the friction dampers provided more precise conditions for the readiness of the technology levels, which was the same for the rubber isolator (TRL=86%) as compared to the slider isolator. (TRL=81%)
