Buildings coupled have been shown to be an attractive method to alleviate dynamic demands on structures. The principle of coupled buildings is that dynamic forces are transferred upon one another in such manner that they work as a group, and consequently reduce the responses of both structures. The focus of this paper is to assess various alternatives of control devices implemented as the coupl...

A damage detection problem is cast in the context of a statistical pattern recognition paradigm. In particular, this paper focuses on applying statistical process control methods referred to as "control charts" to vibration-based damage detection. First, an auto-regressive (AR) model is fitted to the measured time histories from an undamaged structure. Residual errors, which quantify the differ...

Structural sensing, monitoring and control can benefit from wireless communication and embedded computing technologies in terms of installation cost and time. Our prior research has developed low-cost wireless sensing systems for structural monitoring. By incorporating an actuation signal generation module, the functionalities of wireless sensors can be extended to support structural actuation ...

In this paper, we propose a new information theoretic method called structural information to overcome fundamental problems inherent in conventional competitive learning such as dead neurons and deciding on the appropriate number of neurons in the competitive layer. @Our method is based on defining and controlling several kinds of information, thus generating particular neuron firing patterns. ...

Structural vibration mitigation using semiactive control strategies has received special attention recently due to the attractive properties of semiactive devices. The main restriction of a semiactive device is that it can only produce dissipative forces, which may be expressed in mathematical terms as a nonlinear inequality constraint. Standard active control algorithms do not generally accoun...

3.1 Structural Tailoring Technique As revealed in Chaper 2, the boundary-value problem consists of six differential equations of motion (expressed in terms of the displacements wo ,θy,θx ,uo ,vo and φ ), together with the corresponding BCs. Such a set exhibits a complete coupling between the various modes, i.e., primary and secondary warping, vertical and lateral bending, twist and transverse s...

Control systems are used to limit structural lateral deflections during large external loads such as winds and earthquakes. Most recently, the semi-active control approach has grown in popularity due to inexpensive control devices that consume little power. As a result, recently designed control systems have employed many semi-active control devices for the control of a structure. In the future...

Although the application of active control to vibrations has been investigated from many years, the extension of this technology to large-scale systems has been thwarted, in part, by an overwhelming need for computational effort, data transmission and electrical power. This need has been overwhelming in the sense that the potential applications are unable to bear the power, weight and complex c...

To limit the response of structures during external disturbances such as strong winds or large seismic events, structural control systems can be used. In the structural engineering eld, attention has been shifted from active control to semi-active control systems. Unlike active control system devices, semiactive devices are compact, have e cient power consumption characteristics and are less ex...

In this work, the main ideas involved in the design of overlapping and multi-overlapping controllers via the Inclusion Principle are discussed and illustrated in the context of the Structural Vibration Control of tall buildings under seismic excitation. A detailed theoretical background on the Inclusion Principle and the design of overlapping controllers is provided. Overlapping and multi-overl...
