Critical Response of High-Rise Buildings With Deformation-Concentration Seismic Control System Under Double and Multi Impulses Representing Pulse-Type and Long-Duration Ground Motions

Abstract

The critical responses are investigated for a high-rise building with a deformation-concentration seismic control system under double and multi impulses representing pulse-type and long-duration ground motions, respectively. The critical responses were studied for an elastic-plastic multi-degree-of-freedom (MDOF) shear building model under a double impulse and a multi impulse in the previous papers. However, it seems difficult to derive the critical response for a realistic three-dimensional (3-D) nonlinear frame model with a deformation-concentration seismic control system under such double and multi impulses. The criteria on the criticality of the double and multi impulses for the elastic-plastic MDOF shear building model derived in the previous research are extended to this realistic controlled 3-D frame model by regarding the sum of base story shear forces of both main and sub buildings as a key quantity. In the analysis, the concepts of “Double Impulse Pushover (DIP)” and “Multi Impulse Pushover (MIP)” introduced before are used effectively for clarifying the progressive performances for the increasing input level. The analyses of total input energy, frame hysteretic energy and damper dissipation energy are conducted and the criticality of the input derived based on the above-mentioned criteria is investigated in detail.

Analysis and design of non-linear seismic isolation systems for building structures—An overview

“…Palacios-Quinonero et al (2019) applied multiple TMD to inter-storey isolation and adjacent building isolations as illustrated in Figure 3C. Viscous dampers are also applied to adjacent building isolations in Figure 3D by Kasagi et al (2016), Fukumoto and Takewaki (2017), Hayashi et al (2018), Makita et al (2018), Kawai et al (2020Kawai et al ( , 2021, Nakamura et al (2021).…”

A Simple Critical Response Evaluation Method for Base-Isolation Building-Connection Hybrid System Under Double Impulse as Representative of Near-Fault Ground Motion

“…(20) Kawai et al (2021) showed that Δt 0.01 [s] is sufficient enough for the accuracy. It is noted that, since a rapid change of input acceleration may cause the occurrence of unbalanced forces, division of the time interval into short durations is often conducted.…”

“…However, their earthquake resilience is not completely guaranteed for longperiod ground motions with a predominant period of 5-8 s (Kamae et al, 2004;Ariga et al, 2006). Although it is believed in general that passive energy dissipating systems (especially connected building systems) are effective for long-duration and long-period ground motions due to allowing sufficient time for energy dissipation (Luco and Barros, 1998;Basili and Angelis, 2007;Takewaki, 2007;Patel and Jangid, 2011;Takewaki et al, 2012;Richardson et al, 2013;Fukumoto and Takewaki, 2015;Kawai et al, 2021), they are not necessarily resilient against impulsive pulse-type ground motions.…”
