Decentralized state estimation for different substructure layouts of an adaptive high-rise structure

Figures & data

Figure 1. High-rise adaptive demonstrator building with sensors and actuators in Stuttgart, Germany (ISYS, ITO).

Figure 2. Wind speed and direction time series used in the simulation study.

Figure 3. High-rise adaptive structure with original sensor system (a) and the sensor setup resulting from the sensor placement algorithm used in the simulation study (b). The LED-markers are tracked by two cameras, oriented in $\mathit{x}$- and $\mathit{y}$-direction. The ${47}^{\mathrm{th}}$ node serves as sample node for evaluation and is marked in red. (c) Substructures based on RGA for $n_{\mathrm{sub}}=1,2,\dots 6$.

Table 1. Modeled modes for the substructures from bottom to top (compare to Figure 3).

Subsystem $\mathit{i}$	$1$	$2$	$3$	$4$	$5$	$6$	$\sum$
$n_{\mathrm{sub}}=1$ (cen)	$12$						$12$
$n_{\mathrm{sub}}=2$	$6$	$6$					$12$
$n_{\mathrm{sub}}=3$	$6$	$3$	$6$				$15$
$n_{\mathrm{sub}}=4$	$6$	$3$	$3$	$6$			$18$
$n_{\mathrm{sub}}=5$	$6$	$3$	$3$	$3$	$6$		$21$
$n_{\mathrm{sub}}=6$	$3$	$3$	$3$	$3$	$3$	$6$	$21$
