WebSep 21, 2024 · Fling step earthquake occurred due to permeant displacement at the fault and it can be observed parallel to fault or slip direction. This effect gets reflected in the velocity and displacement time histories [14, 16,17,18]. Typical time histories of acceleration, velocity, and displacement are shown in Fig. 4. 2.2 Modeling

WebMar 15, 2024 · The behavior of base-isolated building frame is investigated with the help of a numerical study for far-field and near-field earthquakes with directivity and fling-step effects. Both design-level and extreme-level earthquakes are considered. WebNov 1, 2010 · Generically, fling step is the result of a permanent ground displacement that generates one-sided velocity pulses, whereas forward directivity is a dynamic phenomenon that produces no permanent ground displacement and hence two-sided (reversing) velocity pulses [12], [16], [17], [19], [27].

WebJul 11, 2024 · The fling step effects are the consequences of a permanent ground displacement due to the static deformation field of the earthquake, occurring over a discrete time interval of several seconds as the fault slip is developed (Stewart et al., 2002 ).
