“…The first-mode damping ratio of the vertical vibration shown in Figure 13B is distributed in the range of 1 to 3% for RC systems and 0 to 1% for S structures, similar to the values shown in Figure 9. Here, by substituting Equations ( 15) into (7), we obtain the following equations as the estimated lines of the relationship between the first-mode vertical natural period v T 1 and damping ratio v h 1 .…”

“…[1][2][3]24 In recent years, studies on natural periods and damping ratios that are related to amplitude dependence, damage dependence, and aging have been published. [4][5][6][7]25 However, many of these reports are limited to the horizontal vibration characteristics. Few studies have conducted comprehensive analyses of the observation records for various structural types and buildings with respect to the vertical characteristics.…”

This study focuses on the first‐modal natural periods and damping ratios of buildings in the vertical direction. An auto regression and exogenous (ARX) model is used to identify each vertical natural period and damping ratio. The targets comprise over 3,000 earthquake observation records for 18 buildings comprising reinforced concrete, steel and reinforced concrete, and steel structures. The identified values are summarized for each structural type, and their characteristics are discussed in view of the input amplitude and height of the buildings, compared to the natural period and damping ratio in the horizontal direction. Based on the results, a simple estimation equation is provided for the first‐mode vertical natural period.

Natural period and damping factor are important values in seismic design because of their impact on the response of superstructures when their behavior during an earthquake is estimated. However, commonplace earthquake observation records contain various effects, as represented by the soil-structure interaction. This study focuses on the records of large shaking table tests and investigates the vibration characteristics and time shift for reinforced concrete specimens subjected to more than one large amplitude seismic motion. The experimental data are analyzed using the autoregressive exogenous (ARX) model. Moreover, the effects of the maximum deformation caused by the large seismic motion on the vibration characteristics are investigated.
