Real-time hybrid simulation of a smart outrigger damping system for high-rise buildings

Technical Note: Active and Semi-Active Strategies to Control Building Structures Under Large Earthquake Motion

“…On the other hand, some structural systems seems to be more suitable for integrating control devices because of either the geometric fit between load-bearing and force-control paths, such as tensegrities and active tendons, or the high level of response control effectiveness they achieve when subjected to seismic motion, such as mega-sub controlled structures [Xia, 2012] and controllable outriggers. This latter system has received particular attention lately, especially in terms of the application of MR dampers [Asai et al, 2013a;Chang et al, 2013;Wang et al, 2010], because only few dampers have to be installed between outrigger and perimeter columns for energy dissipation purposes. Finally, the integrated optimization of structure and control scheme has been investigated with the objective to simultaneously obtain optimal structural design and mitigation of the excessive responses of building structures [Hiramoto et al, 2014].…”

Experimental implementation of predictive indicators for configuring a real-time hybrid simulation

“…(33)-(36) measure the general errors over the time history, while Eqs. (37)- (40) are calculated at each time step over the entire time history.…”

Dynamic characteristics of novel energy dissipation systems with damped outriggers

“…Fang [15,16] analyzed damped outriggers with viscous dampers and BRB bracing systems in the reliability perspective. Due to the comparable performance of MR dampers [17,18], Chang et al [19] numerically investigated a single outrigger with MR dampers in a tall building and Asai et al [20] further examined the performance of such smart outriggers system experimentally using real-time hybrid simulation. Until now, damped outrigger systems have been successfully applied to real-world tall buildings, i.e., Saint Francis Shangri-La Towers with a height of 210 m high in Philippine [21] and Gate of South Asia Tower with a height of 366 m in Yunnan, China [22].…”
