Unpaired image-to-image translation is a popular research topic in computer vision and graphics. Recently, the authors of this paper took a similar approach and translated the domain of acceleration responses collected from a steel grandstand ...

Most data-driven structural damage detection methods are built upon the assumption that enough labeled data is available and both training and test data have the same underlying distribution, which limit their successful applications in practical ...

The particle swarm optimization (PSO) algorithm has been widely used to solve optimization problems. One of its main drawbacks is a slow and sometimes premature convergence, which traps the swarm in a local minimum. Several PSO variants have been ...

• A multi-component PSO with leader learning mechanism is proposed for structural damage detection.
• A pool strategy is constructed by using four PSO variants, which guarantees that the algorithm can cooperatively execute multiple search ...

In this paper, for the first time, a variable velocity strategy particle swarm optimization (VVS-PSO) is presented to solve the optimization problems ranging from numerical functions to real-world problems. VVS-PSO introduces a new term added in ...

Structural damage detection is of very importance to improve reliability and safety of civil structures. A novel sensor data-driven structural damage detection method is proposed in this paper by combining continuous wavelet transform (CWT) with ...

An efficient optimization procedure is proposed to detect multiple damage in structural systems. Natural frequency changes of a structure are considered as a criterion for damage presence. In order to evaluate the required natural frequencies, a finite ...

This paper presents a method for structural damage detection using frequency response functions (FRF) obtained from non-destructive vibration tests. It investigates the case of early structural damage in which there is no appreciable change in mass and ...

A method for locating and estimating structural damage in two and three-dimensional analytical models of buildings is presented. Damage is defined in terms of changes in elements stiffness. Since the geometrical transformation matrix used to obtain the ...
