Rolling-type base isolation as a means of earthquake protection is over a century old but
has advanced rapidly in recent years due to an increase in research interest. Significant …

The ductile design principle has been widely adopted in seismic design of structures, so the
main structural components are designed to have the dual functions of bearing and energy …

This paper proposes novel self-centering (SC) seismic base isolators by utilizing shape
memory alloy U-shaped dampers (SMA-UDs) with favorable superelastic behavior. Two …

This paper presents an extensive experimental study of a low-cost, high-performance
seismic isolator comprising a deformable sphere rolling on concrete surfaces. Polyurethane …

With the aim of unifying the damping concept and evaluating the amount of damping in a
structure, this paper investigates whether friction action can be equivalent to traditional …

This paper describes the behavior of a low-cost seismic isolator comprising a grout-filled
tennis ball rolling on concrete plates. The isolator could be used for isolating lightweight …

This paper investigates a steel moment resisting frame (MRF) with a novel type of self‐
centering (SC) base isolators, wherein superelastic shape memory alloy (SMA) U‐shaped …

The rolling motion of mutually orthogonal rollers respectively sandwiched between two
bearing plates in which one or both have V‐shaped sloping surfaces makes the sloped …

The present paper shows the results of an experimental study on new rolling seismic
isolators made with steel cylindrical elements arranged on two levels, interposed between …

The shear keys are set in a seismic isolation system to resist the long-term service loadings,
and are cut off to isolate the earthquakes. This paper investigated the influence of shear …
