- 요약Seismic isolation is a mature technology that has been proven to significantly reduce seismic demands on the superstructure and protect it from damage even during large earthquakes. However, the technology still has not found wide application outside commercial, high-budget projects, mainly because of the high cost of implementing an isolation system. In recent years, simple sliding isolation systems that use low-cost materials have gained attention for their potential to make seismic isolation economically feasible even in affordable housing. However, shaking-table tests and seismic analyses of elastic structures with sliding bearings show that large accelerations and forces occur in the superstructure every time the sliding interface transitions from stiction to relative sliding between the surfaces in contact. In current earthquake engineering design practice, this phenomenon is not explicitly accounted for, potentially leading to an unconservative design of the superstructure. This can be especially problematic if the technology is being applied in seismically vulnerable structures, such as those with masonry elements. The precise magnitude and potential effects of stick-slip transition phenomena are studied in this work.The first part of this work consists of experimental studies to characterize the frictional behavior of steel-polymer interfaces that are used-or have the potential for being used-in low-cost seismic isolation systems, culminating with the development of a friction model that is able to capture the observed behavior. The second part consists of parametric and analytical studies to evaluate the seismic response of sliding structures, considering the stick-slip transition phenomena. This part includes the development of an analytical equation that estimates the peak pseudo-acceleration response of a sliding structure as a function of a few structural, frictional, and ground-motion properties. The results of these studies improve the reliability of economically isolated structures and facilitate their design.
