RISSubstructural Damage Detection With Incomplete Information of the Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a substructural damage identification approach without the information of responses and forces at the interface degrees-of-freedom. It is based on the response reconstruction ...
Crack Identification in Thin Plates With Anisotropic Damage Model and Vibration Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many approaches on modeling of cracks in structural members have been reported in the literatures. However, most of them are explicitly developed for the purpose of studying the changes in ...
Delamination Detection-Oriented Finite Element Model for a Fiber Reinforced Polymer Bonded Concrete Plate and Its Application With Vibration Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Delamination is a common type of damage in laminated fiber-reinforced polymer (FRP) composites. As FRP composites are becoming popular in upgrading and strengthening of civil concrete structures, ...
Substructural Response Reconstruction in Wavelet Domain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An approach for structural response reconstruction in a substructure using the unit impulse response function in the wavelet domain is presented. The forces at the interface degrees-of-freedom ...
Sensitivity of Uniform Load Surface Curvature for Damage Identification in Plate Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper a new sensitivity-based method of using measured modal parameters to locate and quantify damage is developed for plate-like structures. With the measured incomplete modal data for ...
System Identification Including the Load Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A number of methods for the identification of the axle loads of vehicles using a bridge’s static and pseudo-dynamic responses have been developed, 12345. Identification of moving loads has been ...
Wavelet-Based Sensitivity Analysis of the Impulse Response Function for Damage Detection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the extraction of the wavelet-based impulse response function from the acceleration response using the discrete wavelet transform (DWT). The analytical formulation of the ...
Identification of Linear Time-Varying Dynamical Systems Using Hilbert Transform and Empirical Mode Decomposition Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses the identification of linear time-varying multi-degrees-of-freedom systems. The identification approach is based on the Hilbert transform and the empirical mode decomposition ...
Identification of Moving Loads on an Orthotropic Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method is presented to identify indirectly loads moving on an orthotropic plate. The loads are in a group of two forces or four forces. The dynamic behavior of the plate under the action ...
Time Domain Identification of Moving Loads on Bridge Deck
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new time domain method is presented to identify moving loads on a bridge deck based on the measured responses. The bridge deck is modeled as an orthotropic plate and the loads are modeled ...
