Abstract: An optimal control algorithm using neural networks is proposed. The controller neural network is trained by a training rule developed to minimize cost function. Both the linear structure and the nonlinear structure can be ...

Abstract: This paper examines the ASCE first generation benchmark problem for a seismically excited cable-stayed bridge, and proposes a new semiactive control strategy focusing on inclusion of effects of control-structure interaction. ...

Abstract: Small- and medium-sized construction sites are not efficiently managed because of the lack of budget and labor in safety management. In this paper, a real-time struck-by hazards detection system based on computer vision ...

Abstract: A new semiactive control strategy that combines a neurocontrol system with a smart damper is proposed to reduce seismic responses of structures. In the proposed semiactive control system, the improved neurocontroller, which ...

Abstract: A solution method that can calculate the eigenproblem for large structures with multiple or close natural frequencies is presented. The method is formulated by the accelerated Newton-Raphson method for the transformed ...

Abstract: This note proposes an improved eigenvalue-counting method based on the argument principle by introducing Rombouts’ algorithm, which is a stable, efficient, and accurate algorithm to calculate the coefficients of the ...

Abstract: Magnetorheological (MR) dampers are one of the most promising new devices for structural vibration mitigation. Because of their mechanical simplicity, high dynamic range, low power requirements, large force capacity, and ...

Abstract: This paper proposes an implementation of modal control for seismically excited structures using magnetorheological (MR) dampers. Many control algorithms such as clipped-optimal control, decentralized bang-bang control, and ...

Abstract: This paper experimentally investigates the feasibility of an adaptive passive control system, which consists of a magnetorheological (MR) fluid damper and an electromagnetic induction (EMI) part, for suppressing vibration ...
